Description

A kind of harmless treatment equipment and burying method of livestock and poultry corpses

technical field

The invention relates to a harmless treatment equipment and burial method for livestock and poultry corpses, which can quickly and batch process livestock and poultry corpses, and can inhibit the external diffusion of animal pathogenic bacteria during management, and prevent the leakage of stench and sewage.

Background technique

When dealing with livestock and poultry infected or suspected to be infected with infectious diseases such as avian influenza (Avian Influenza, AI) and foot-and-mouth disease, it is very important to suppress the risk of external spread of animal pathogens.

At present, livestock and poultry infected or suspected to be infected with animal pathogenic bacteria are mainly disposed of by burying, burning or rendering away from living areas after being killed. Although the existing burial method has the advantages of low initial cost and batch processing of livestock and poultry carcasses, it requires continuous management of the burial area. Pollution of ground water. Although the incineration method can kill most of the animal pathogens in the animal carcasses and minimize the residues, it consumes a lot of energy and is difficult to process in batches. The chemical production method is a relatively economical and environmentally friendly method. According to the death degree of animal pathogenic bacteria, the dead body can be recycled into feed, fertilizer or industrial raw materials, but it is also difficult to achieve batch processing. Many existing methods, including the burial method, will cause a large amount of sewage to leak out during the treatment of livestock and poultry carcasses, causing soil and groundwater pollution, and will emit foul odors, and there is also a risk of outward spread of animal pathogens.

A great deal of research has been done to overcome the drawbacks of the existing treatments described, but mostly by reducing the drawbacks by making small improvements to the existing methods.

Therefore, there is a need for an economically feasible processing method that can solve existing problems based on the existing processing methods for livestock and poultry carcasses. Especially in order to suppress the external diffusion of animal pathogenic bacteria, a more effective livestock and poultry carcass treatment equipment and burying method are needed.

Detailed ways

Specific embodiments of the present invention will be described in detail below. The technical terms that are not redefined in the present invention shall be interpreted with the meanings generally used in this field. Recognized parts in the description and drawings of the present invention may be omitted from description, and may be described with exaggeration within the scope not to obscure the gist of the present invention.

The livestock and poultry corpse treatment equipment and the burying treatment method of the present invention can solve the problems in the existing livestock and poultry corpse treatment.

The livestock and poultry corpse processing equipment of the present invention uses oxygen nano-bubble water to degrade livestock and poultry corpses, so the equipment can be excavated and directly installed on the ground.

In the present invention, the livestock and poultry corpse treatment equipment (100) that excavates earthen pit to build is formed by burying pond (140), the active layer (110) of bottom layer inside burying pond (104), the dead body degradation layer (150) above active layer (110) ), and the deodorizing embedding layer (160) above the corpse degradation layer (150). Wherein, the active layer (110) includes aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water, and the corpse degradation layer (150) includes aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water , the deodorization embedding layer (160) includes aerobic thermophilic microorganisms for deodorization and a gas-permeable material.

In the present invention, an earth pit is excavated at the burial site to build a burial pool, which includes a soil purification layer, an active layer, a corpse degradation layer and a deodorizing burial layer.

For the batch processing of livestock and poultry carcasses, at first select the burial site, dig the earth pit, and build the burial pond. When building a buried pond in a land type buried site, a waterproof membrane can be laid in the buried pond to prevent sewage leakage and rainwater infiltration. The size of the burial pond depends on the type of livestock and poultry to be buried and the weight of the carcass.

In the present invention, the livestock and poultry carcasses processing equipment (100) installed by excavating earth pits further includes a waterproof membrane (120) under the buried pool and a waterproof membrane protective layer (130) arranged under the waterproof membrane.

The selection of the waterproof membrane can be any material as long as it can prevent sewage and water seepage, preferably a waterproof plastic membrane. In Example 1 of the present invention, a waterproof plastic film with a thickness of not less than 0.1 mm is used, and more than two layers are laid. When laying, the ground area of the buried site and the height of the inner wall surface shall be fully considered, so that the outer earth embankment can be completely covered.

The protective layer of the waterproof membrane is specially laid to avoid leakage of sewage or water due to the perforation of the waterproof membrane. Porous fibers with better moisture absorption can be selected, preferably non-woven fabrics. After building a buried pond of standard size, cover the bottom of the buried pond and the inner wall of the pond with non-woven fabrics, the thickness of which can be 5-10mm, and there is no limit to this.

The livestock and poultry corpse processing equipment (100) installed in excavating earth pits in the present invention also includes a soil purification layer (170). After the soil purification layer (170) is completed, a waterproof membrane and a waterproof membrane protection layer are laid.

Aerobic thermophilic microorganisms are sprayed to form a soil purification layer (170), preferably, sprayed evenly at a rate of 400g per 3.3m ² . The soil purification layer can degrade the sewage leaked due to the damage of the waterproof membrane and the waterproof membrane protective layer. For example, when using the non-woven fabric as a waterproof membrane protective layer, before covering the non-woven fabric, the aerobic thermophilic microorganisms are evenly sprayed on the bottom of the buried pool according to the proportion of 3.3m ² 400g in advance, and the bacteria in the livestock and poultry can be completely removed. Sewage left over from the process of corpse degradation.

The active layer (110) of the livestock and poultry carcasses processing equipment (100) installed in excavating earth pits in the present invention also includes a porous air supply pipe (101) dedicated to supplying air. A ring blower (104) sends air to the porous air supply pipe (101) through the connecting pipe (102), and continuously maintains the aerobic environment of the livestock and poultry carcass processing equipment through the active layer (110).

The porous air supply pipe may be a porous flexible pipe. Because the connecting pipe is the connection between the porous air supply pipe and the annular blower, it is preferably a hard pipe, and it is perpendicular to the inner wall of the buried pool.

Most of the connecting pipes can be connected with the air distribution pipe (103). The air distribution pipe (103) distributes the air and oxygen provided by the annular blower (104) to the porous air supply pipe (101) through the connecting pipe (102), so it needs to be positioned according to the porous air supply pipe on the waterproof membrane (120). (101) Quantity, assemble reducing tee, short nipple, elbow, etc.

In the present invention, after the deodorizing embedding layer (160) of the livestock and poultry corpse processing equipment (100) installed in the digging pit is formed, a light-shielding film (105) needs to be laid on the deodorizing embedding layer (160). The shading film is preferably a breathable material with a shading rate of not less than 95%, so as to prevent the loss of the deodorizing sealing layer caused by external intrusions such as rain and wind. Add a rain-shielding film (106) on the upper layer of the light-shielding film (105). Preferably, the rain-shielding film covers the embankment and the drainage pipeline in the form of a plastic greenhouse, and the internal distance with the deodorizing embedding layer is controlled at about 1m. .

The present invention generally adopts the mode of excavating earth pits at selected burial sites to construct buried ponds, but in the case of being unable to excavate earth pits, livestock and poultry corpse processing equipment can be built on the ground.

The livestock and poultry corpse treatment equipment (10) installed on the ground is generally selected in the isolation area or the farm, including the buried structure (11), the active layer (12) at the inner bottom of the buried structure (11), and the active layer (12) located in the active layer (12). ) on the corpse degradation layer (13) and the deodorizing embedding layer (14) on the corpse degradation layer (13). Wherein, the active layer (12) includes aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water, and the corpse degradation layer (13) includes aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water , the deodorizing embedding layer (14) includes aerobic thermophilic microorganisms and gas-permeable materials for deodorization.

The burial structure (11) is built for installing livestock and poultry corpse treatment equipment on the ground, and its interior is divided into an active layer, a corpse degradation layer and a deodorizing and embedding layer. The livestock and poultry corpse processing equipment (10) installed on the ground as shown in Figure 1, can move as required. The burial structure (11) is suitable as long as it is a structure suitable for burying livestock and poultry carcasses, preferably an anti-seepage structure, such as concrete, glass fiber reinforced plastic (FRP), plastic or metal containers, and the like.

The active layer (12) of the livestock and poultry carcasses processing equipment (10) installed on the ground also includes a porous air supply pipe (15) specially for supplying air. The annular blower (17) delivers air to the porous air supply pipe (15) through the connecting pipe (16), the annular blower (17) provides air and oxygen, and maintains the continuous aerobic state of the livestock and poultry carcass processing equipment through the active layer (12) surroundings.

The livestock and poultry corpse treatment equipment (10) installed on the ground also includes an exhaust pipe (18) and a ceiling (19). The ceiling (19) can use materials with thermal insulation properties, such as vinyl plastics, tents, metals, plastics, straw or mixtures of these materials. The function of the exhaust pipe (18) is to discharge the gas generated inside the livestock and poultry corpse treatment equipment (10), and then install the livestock and poultry corpse treatment equipment (10) after sealing with the ceiling. Exhaust pipes use materials with good heat resistance and corrosion resistance, preferably polyvinyl chloride pipes. Inside the livestock and poultry carcass processing equipment, the bottom of the exhaust pipe should be in contact with the livestock and poultry carcasses, preferably a perforated lead pipe and a perforated straight pipe with a diameter greater than 100mm. The end of the exhaust pipe is connected with a U-shaped pipe to prevent the inflow of rainwater, and the gas can be discharged to the ground through the U-shaped pipe. When the installation site of the livestock and poultry corpse processing equipment (10) or the livestock and poultry corpse processing capacity is small, the exhaust pipe may not be installed.

In the present invention, in the livestock and poultry carcass treatment equipment installed by using the buried structure on the ground or excavating the earth pit, in order to continuously activate the aerobic thermophilic microorganisms, the air-permeable material can provide the balance of moisture and oxygen from the oxygen nano-bubble water, Maintain a breathable environment with a certain gap. A mixture of bran or litter, sawdust, fallen leaves, hay, whole-cooked compost, etc., or other material that can provide an air permeable environment is preferred.

The active layer in the livestock and poultry corpse processing equipment includes aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water. The active layer is different from the corpse degradation layer, and achieves the purpose of completely removing the sewage produced by the degradation of livestock and poultry corpses in the corpse degradation layer, and continuously maintaining the activity of aerobic thermophilic microorganisms inside the livestock and poultry corpse treatment equipment. The sewage generated in the corpse degradation layer will be evaporated and degraded by the heat generated by the aerobic thermophilic microorganisms in the corpse degradation layer, but a part will still penetrate into the active layer. The heat generated by the aerobic thermophilic microorganisms in the active layer can completely remove this part of the sewage, and when the livestock and poultry carcasses are processed in batches, the active layer can provide the inside of the treatment equipment with the oxygen, air and moisture needed to degrade the livestock and poultry carcasses for a long time Wait. The inside of the active layer includes a porous air supply pipe, which is supplied with air by an annular blower. When the carcass degradation layer starts to degrade the carcass, it does not need to supply external oxygen, air and water in the first 48 hours, but after 48 hours, it needs to supply air through the porous air supply pipe to maintain the aerobic thermophilicity of the livestock and poultry carcasses treatment equipment. microbial activity.

Preferably, the air-permeable material in the active layer is put in at a ratio of 10 to 30 tons per 100 tons of livestock and poultry carcasses, the aerobic thermophilic microorganisms are put in at a ratio of 1 to 1.5 tons per 100 tons of livestock and poultry carcasses, and the oxygen nano-bubble water According to the ratio of 1.0-2.0 tons per 100 tons of livestock and poultry carcasses, but there is no limit to this.

In the livestock and poultry corpse processing equipment, the livestock and poultry corpse degradation layer is located above the active layer and includes aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water.

Livestock and poultry corpses are mixed into the corpse degradation layer, and the degradation of the livestock and poultry corpses is induced by aerobic thermophilic microorganisms.

When putting in livestock and poultry carcasses, there is no limit to the types of livestock and poultry, and a large number of livestock and poultry can be put in units of tons according to the scale of the processing equipment. Preferably, the aerobic thermophilic microorganisms in the carcass degradation layer are put in at a ratio of 0.5 to 1.0 tons per 100 tons of livestock and poultry carcasses, the gas permeable materials are put in at a ratio of 10 to 30 tons per 100 tons of livestock and poultry carcasses, and the oxygen nano-bubble water 1.0-2.0 tons per 100 tons of livestock and poultry carcasses, but there is no limit to this.

The main function of the oxygen nano-bubble water in the corpse degradation layer in the livestock and poultry corpse treatment equipment is to replace the air in the early stage of burial to activate aerobic thermophilic microorganisms. Aerobic thermophilic microorganisms reached a stable active state within 48 hours of delivering oxygen nanobubble water. During this period, aerobic thermophilic microorganisms continue to proliferate in order to maintain the degradation activities of livestock and poultry carcasses. Oxygen nanobubble water is responsible for maintaining the aerobic conditions inside the landfill until the aerobic thermophilic microorganisms reach a stable state of activity. Therefore, no external supplemental oxygen is required for the preceding 48 hours. This technical feature makes it possible to degrade the dead body even if there is no external oxygen supply in the initial stage of burying the dead body of livestock and poultry, and can cut off the connection between the buried pond and the outside world within at least 48 hours. Therefore, the device can fundamentally prevent the external spread of animal pathogenic bacteria in livestock and poultry carcasses. The oxygen nano-bubble water contains very tiny nano-bubbles, which can provide oxygen to the degradation layer of the corpse or even the entire buried pool, so as to realize the activity balance of aerobic thermophilic microorganisms.

In the initial stage of aerobic thermophilic microorganisms degrading livestock and poultry carcasses, the aerobic environment is maintained by oxygen nano-bubble water, and the components required for the activation of aerobic thermophilic microorganisms such as amino acids are provided by livestock and poultry corpses, and the activated aerobic thermophilic microorganisms Heat is generated by breathing. Since the inside of the buried pond is isolated from the outside at the initial stage of degradation, the heat accumulation rate is faster than when there is external air supply, and the internal temperature of the buried pond can reach 45-70°C and above. Due to the rise in temperature, other bacteria except aerobic thermophilic microorganisms are killed, and aerobic thermophilic microorganisms are continuously activated to continuously degrade the corpse. The bacteria that are killed as the temperature rises include Escherichia coli, Vibrio cholerae, typhoid bacillus, Salmonella and other pathogenic bacteria, as well as animal pathogenic bacteria and highly infectious viruses such as avian influenza and foot-and-mouth disease. Such harmful pathogenic bacteria or viruses can be killed within 48 hours under high temperature conditions of 45-70°C and above. Therefore, in the first 48 hours of carcass treatment, when there is no external oxygen supply and oxygen nanobubble water is used to activate aerobic thermophilic microorganisms to degrade the carcasses, the pathogenic bacteria or viruses in the carcasses will not leak out.

In the livestock and poultry corpse treatment equipment, the deodorizing embedding layer is located above the corpse degradation layer, and includes aerobic thermophilic microorganisms for deodorization and gas-permeable materials. In order to improve deodorization efficiency, it is preferable to add oxygen nano-bubble water to the deodorization embedding layer. Oxygen in the corpse degradation layer oxygen nano-bubble water will penetrate into the deodorization embedding layer.

The purpose of laying the deodorizing embedding layer is to remove the stench produced in the early stage of the degradation of livestock and poultry carcasses in the carcass degradation layer. The laying thickness of the deodorizing degradation layer is 50cm, excluding livestock and poultry carcasses.

In the deodorizing embedding layer of the livestock and poultry corpse treatment equipment, preferably, the air-permeable material is placed in a ratio of 10 to 30 tons per 100 tons of corpses, and the ratio of aerobic thermophilic microorganisms is 1 to 1.5 tons per 100 tons of corpses For delivery, the oxygen nano-bubble water is delivered at a ratio of 1.0 to 2.0 tons per 100 tons of corpses, but it is not limited by this. The aerobic thermophilic microorganisms used for deodorization of the deodorizing embedding layer may use more than one recognized mixture of aerobic thermophilic microorganisms, and may also use aerobic thermophilic microorganisms different from the corpse degradation layer.

The gas-permeable materials, aerobic thermophilic microorganisms and oxygen nano-bubble water used in the active layer, corpse degradation layer and deodorizing embedding layer of the present invention can be controlled in appropriate amounts according to the activity degree of the aerobic thermophilic microorganisms.

The annular blower in the present invention is responsible for conveying air and oxygen from the outside, and belongs to the common blower. That is to say, other air blowers can be used instead of the annular air blower in the present invention on the premise that the external air and oxygen can be delivered to the porous air supply pipe of the active layer of the livestock and poultry carcass treatment equipment through the connecting pipe.

A kind of livestock and poultry corpse burying method of the present invention is described below. The livestock and poultry carcass burial method is a method of disposing of livestock and poultry carcasses in the external soil area, so it is more suitable for processing large-scale livestock and poultry carcasses compared with livestock and poultry carcasses processing equipment.

The method for burying livestock and poultry corpses in the present invention comprises the following five steps: (a) constructing a burying pond (140) for burying the corpses; (b) laying a waterproof membrane (120) on the inner bottom layer of the burying pond (140); (c) laying an active layer (110) comprising a gas-permeable material above the waterproof membrane (120); (d) laying an active layer comprising livestock and poultry carcasses, aerobic thermophilic microorganisms, and breathable materials above the active layer (110). The dead body degradation layer (150) of non-toxic material and oxygen nano-bubble water and (e) lay the deodorization embedding layer ( 160).

In the method for burying livestock and poultry corpses, first select a burial site to build a burial pond, preferably a burial pond with a standard size of 6m in width, 2.5m in height, and 23m in length (345m ³ ), depending on the type and corpse of livestock and poultry to be buried. weight. Due to the need to use aerobic thermophilic microorganisms, the ground in the buried area should be kept flat during construction to ensure that the oxygen nanobubble water added in the future can be evenly transported.

In the method for burying livestock and poultry corpses, a waterproof membrane is laid after the construction of the burial pond is completed, so as to prevent the leakage of sewage generated by the livestock and poultry corpses before they are degraded. The material of the waterproof membrane must be a material that can prevent sewage and moisture from seeping out, preferably a waterproof plastic membrane, and lay more than 2 layers of waterproof plastic membranes with a thickness greater than 0.1mm. When laying, the ground area of the buried site and the height of the inner wall surface shall be fully considered, so that the outer earth embankment can be completely covered.

In the method for burying livestock and poultry corpses, before laying the waterproof membrane (120), a waterproof membrane protective layer (130) needs to be laid first to achieve the purpose of protecting the waterproof membrane (120).

Before the waterproof membrane and the waterproof membrane protective layer are laid on the bottom surface of the buried pool, a soil purification layer (170) is preferably built to treat the sewage flowing out due to the damage of the waterproof membrane.

The waterproof membrane protection layer is specially laid to prevent the leakage of sewage or water caused by the perforation of the waterproof membrane. Porous fibers with better moisture absorption can be selected, preferably non-woven fabrics. After building a buried pond of a standard size, cover the bottom of the buried pond and the inner wall of the pond with non-woven fabrics. The thickness is preferably 5-10mm, and there is no limit to this. Before laying non-woven fabrics, spray a small amount of aerobic thermophilic microorganisms at a rate of 400-600g per 3.3m ² on the bottom of the buried pond in advance to form a soil purification layer to completely remove the sewage that may remain during the degradation of livestock and poultry corpses, etc. the goal of.

In the method for burying livestock and poultry corpses, after the waterproof membrane (120) is laid in the embedding pond (140), an active layer (110) is laid thereon.

The air-permeable material is covered on the waterproof membrane to form an active layer. The active layer includes aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water.

The active layer also includes a porous air supply pipe, which is connected to the porous air supply pipe through an annular blower to transport air and water, maintain a certain gap in the buried pool, and achieve the purpose of continuously activating aerobic thermophilic microorganisms to ensure an aerobic environment. In addition, the active layer can absorb and degrade rainwater infiltrated into the buried pond or sewage that may remain from livestock and poultry carcasses, preventing it from leaking out.

In the method for burying livestock and poultry corpses, the air-permeable material is preferably a mixture of chaff or litter, sawdust, fallen leaves, hay, fully cooked compost, etc., or other materials that can provide a breathable environment. What used in the embodiment 1 of the present invention is the coarse bran mixture of coarse bran, sawdust, fallen leaves, hay, fully-cooked compost, after mixing the coarse bran mixture and aerobic thermophilic microorganisms, bedding on the waterproof plastic to form an active layer .

In the livestock and poultry corpse burying method, before the waterproof membrane (120) and the active layer (100) are laid, the porous air supply pipe (101) is laid on the waterproof membrane (120), and it is connected with the connecting pipe (102) , and then the connecting pipe (102) is exposed to the outside world and connected with the air distribution pipe (103).

The porous air supply pipe has the function of supplying air for the purpose of continuously activating aerobic thermophilic microorganisms inside the buried pond. As long as the porous air supply pipe is a porous soft pipe, it should be laid in U-shape in multiple rows inside the buried pool of standard size, and the pipes should be prevented from being entangled with each other or being bent in the landfill to hinder air delivery.

The connecting pipe is a connecting pipe between a porous air supply pipe and an air distribution pipe, preferably a hard pipe, and is perpendicular to the lateral side of the inner wall of the buried pool. It is preferable to fix the connecting pipe with adhesive or tape to prevent damage to the waterproof membrane, and it is not recommended to use fixing tools such as alignment pins that may cause perforation of the waterproof membrane.

The air distribution pipe (103) distributes the air provided by the annular blower (104) to the porous air supply pipe (101) through the connecting pipe (102). Quantity, assemble reducing tee, short nipple, elbow, etc.

In the method for burying livestock and poultry corpses, the air distribution pipe plays the role of maintaining the continuous activity of aerobic thermophilic microorganisms by delivering air and oxygen to the inside of the burying pool, but it cannot be started within the first 48 hours after burying the livestock and poultry corpses . After burying the livestock and poultry carcasses, if air and oxygen are supplied through the air distribution pipe immediately, the pathogenic bacteria remaining in the livestock and poultry carcasses may leak to the outside of the burial pool. Therefore, the aerobic thermophilic microorganisms were activated by the oxygen nanobubble water inside the buried tank without using the air distribution pipe to supply air and oxygen during the first 48 hours.

In the method for burying livestock and poultry corpses, after the active layer (110) is completed, a corpse degradation layer (150) mixed with livestock and poultry corpses, aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water is laid thereon.

The livestock and poultry carcasses are not limited by types, and batches of livestock and poultry carcasses greater than or equal to 1 to 100 tons can be mixed.

Oxygen nanobubble water in the cadaver degradation layer can activate aerobic thermophilic microorganisms in the initial stage of cadaver degradation. Aerobic thermophilic microorganisms reach a stable active state within 48 hours of supplying oxygen nanobubble water, and can continuously proliferate and degrade livestock and poultry carcasses. Oxygen nanobubble water can maintain aerobic conditions inside the landfill until the aerobic thermophilic microorganisms reach a stable active state, so no external oxygen supply is required for the first 48 hours. This technical feature makes it possible to degrade the dead body even if there is no supply of outside air and oxygen at the initial stage of burying the dead body of livestock and poultry, and can cut off the connection between the buried pond and the outside world within at least 48 hours. Therefore, the method can fundamentally prevent the external spread of animal pathogenic bacteria in livestock and poultry carcasses.

In the early stage of aerobic thermophilic microorganisms degrading carcasses, the aerobic environment is maintained by oxygen nano-bubble water, amino acids and other components required by aerobic thermophilic microorganisms are provided through the degradation of livestock and poultry carcasses, and the aerobic properties are activated. Thermophilic microorganisms generate heat through respiration.

With the generation of heat, at the initial stage of degradation, since the inside of the buried pond is isolated from the outside, heat can accumulate rapidly, and the temperature inside the buried pond can rise to 45-70°C and above. Due to the rise in temperature, other bacteria except aerobic thermophilic microorganisms are killed, while aerobic thermophilic microorganisms are continuously activated and continue to degrade the corpse. The bacteria that are killed as the temperature rises include Escherichia coli, Vibrio cholerae, typhoid bacillus, Salmonella and other pathogenic bacteria, as well as animal pathogenic bacteria and highly infectious viruses such as avian influenza and foot-and-mouth disease. Such harmful pathogenic bacteria or viruses can be killed within 48 hours under high temperature conditions of 45-70°C and above. Therefore, as shown in the present invention, in the first 48 hours of carcass treatment, there is no external oxygen supply, and only when aerobic thermophilic microorganisms are activated by oxygen nano-bubble water to degrade the carcasses of livestock and poultry, the pathogenic bacteria or viruses on the carcasses of livestock and poultry Will not leak.

In the livestock and poultry corpse burying method, after the corpse degradation layer (150) is completed, a deodorizing embedding layer (160) mixed with aerobic thermophilic microorganisms, gas-permeable materials and oxygen nano-bubble water is formed above it.

The deodorizing embedding layer is used to remove the stench produced by the degradation of livestock and poultry corpses in the corpse degradation layer.

The aerobic thermophilic microorganisms in the deodorizing embedding layer may include at least one recognized mixture of aerobic thermophilic microorganisms, which may be different from the aerobic thermophilic microorganisms in the cadaver degradation layer.

In the livestock and poultry corpse treatment method, after the deodorizing sealing layer is completed, an earth embankment (107) is built outside the embedding site (140), and a drainage pipeline (108) and a water storage tank need to be built outside the earth embankment (107) .

The surroundings of the earth embankment should prohibit the contact of people and animals and prevent the intrusion of rainwater. It is recommended that the height and thickness of the embankment should not be less than 0.5m.

Preferably, a drainage pipeline with a depth of not less than 0.3m is built on the outside of the embankment to prevent rainwater from scouring the treatment equipment and ensure smooth drainage of the rain-shielding equipment. After the drainage pipeline is built, an earth embankment with a height of not less than 0.3m shall be built around it to prevent rainwater from flowing in.

Preferably, an external water storage tank connected to the drainage pipeline and capable of collecting rainwater that has flowed into the drainage pipeline is installed at one end of the drainage pipeline, and the storage tank is not less than 0.5m ³ .

In the livestock and poultry corpse burying method, after the deodorizing embedding layer (160) is completed, a light-shielding film (105) is laid on it.

The light-shielding film is preferably made of a gas-permeable material with a refractive index not lower than 95%, so as to prevent the deodorant embedding layer from being washed away by rain, wind and other external intrusions.

In the method for burying livestock and poultry corpses, after the light-shielding film (105) is laid, a rain-shielding film (106) is laid on top of it.

Preferably, the rain-shielding film is in the form of a plastic greenhouse, completely covering the embankment and the drainage pipeline, and the internal distance between it and the deodorizing embedding layer is controlled at about 1m.

The aerobic thermophilic bacteria (Aerobic Thermophilic Bacteria) in the present invention is a kind of microorganism that can proliferate in aerobic condition and high temperature environment, and the suitable temperature of its growth is also different in different types, but generally at a high temperature above 50°C environment are more active development. The aerobic thermophilic microorganisms used in the present invention can degrade animal carcasses under aerobic conditions, so as to prevent foul odors from being generated when the carcasses are degraded. As the aerobic thermophilic microorganism used in the present invention, it is preferable to use a thermophilic microorganism that can survive at a high temperature of 50 to 75°C. This microorganism can degrade the corpse even at a high temperature of 50-75°C. Aerobic thermophilic microorganisms are directly isolated and used in the composting and decomposing process of livestock and poultry manure, and can also be purchased. Any recognized aerobic thermophilic microorganisms can be used, but microorganisms suitable for the degradation of livestock and poultry carcasses are preferred, such as Bacillus stearothermophilus (Bacillus stearothermophilus), Speroterius Nauta u (Nitrobacter genus), Bacillus subtilis (Bacillus subtilis), red Pseudomonas (Rhodopse udomonas), Rhodospirillum (Rhodospirillum), Sonora desert bacillus (Bacillus sonorensis), amylobacter (Bacillusthermoamylovorans) or a mixture of two or more of them.

In the present invention, aerobic thermophilic microorganisms may be used as they are, or microbial preparations including or replacing aerobic thermophilic microorganisms may be used. The microbial preparation is prepared by mixing the culture solution of aerobic thermophilic microorganisms and its carrier, and the carrier can use rice bran, sawdust, fallen leaves, hay and compost.

Preparation Example 1 of a microbial preparation that can be used in the present invention is as follows: Microorganisms are inoculated on a culture medium and cultured. The culture medium is prepared by uniformly mixing tryptone, yeast extract, glucose, sodium chloride (NaCl), dipotassium hydrogen phosphate (K ₂ HPO ₄ ) and water. After the microorganisms are inoculated on the culture medium, culture is carried out at 30-40° C. for 1-3 days to obtain a culture solution. Next, the medium is mixed with the carrier. After the culture medium is absorbed by the carrier, the microorganisms are also fixed on the carrier. At this time, the preferred weight ratio of the culture solution to the carrier is 1:10-50, without limitation. Finally, the prepared microbial preparation is mixed with the livestock and poultry carcasses and put into the livestock and poultry degradation layer.

The livestock and poultry degradable layer of the present invention also includes oxygen nano-bubble water, and its function is to activate aerobic thermophilic microorganisms under the condition of no oxygen supply within the first 48 hours after burying the livestock and poultry carcasses.

The oxygen nano-bubble water in the present invention can provide the oxygen and oxygen required for the early activation of aerobic thermophilic microorganisms in the livestock and poultry corpse burial pool by dissolving nano-sized liquid oxygen at a concentration tens or even hundreds of times higher than the saturated saturation concentration. moisture.

The oxygen nano-bubble water is provided through a bamboo nano-bubble generating film made of bamboo irradiated with radiation. After the bamboo skin is removed and the bamboo micropores are obtained by radiation irradiation, the bamboo nano-bubble generation film is made by using the bamboo with the micropores. As radiation, gamma rays, electron beams, or ion beams can be used. Pressure is applied to the bamboo nano-bubble generating membrane in water to generate oxygen bubbles to produce oxygen nano-bubble water. The method can be used to produce oxygen nano-bubble water with nano-bubbles of 80-120 nm and an average individual number of 3.00×10 ⁸ /ml.

In the present invention, the nanobubble size of oxygen nanobubble water can be less than 150nm, 130nm-150nm, less than 130nm, 130nm-100nm, less than 100nm, 100nm-80nm, less than 80nm. The number of individual nanobubbles in the oxygen nanobubble water may be 2.00×10 ⁸ /ml or more, 2.00×10 ⁸ /ml to 3.00×10 ⁸ /ml, preferably 3.00×10 ⁸ /ml or more. Oxygen nanobubble water can maintain a steady state at high temperatures, even without surfactants, and can also activate aerobic thermophilic microorganisms in simple mixing. Even if the oxygen nano-bubble water of the present invention is stored at room temperature for 3 months, the size of the nano-bubbles can be kept constant, and the number of the nano-bubbles can be kept above 2.00×10 ⁸ /ml. Therefore, in the present invention, without supplying air for at least 48 hours, aerobic thermophilic microorganisms can also be continuously activated to degrade livestock and poultry carcasses.

In the present invention, the activation of aerobic thermophilic microorganisms can cause a high-temperature environment inside the buried pool, and the degree of degradation of the corpse can be observed with the naked eye within 2 weeks. The degradation speed is fast, and the management cycle of the buried site can be shortened to within 6 months, improving Land utilization rate, saving maintenance cost.

In the present invention, the high-temperature environment not lower than 45-70°C formed during the degradation process of livestock and poultry carcasses can kill animal pathogenic bacteria, avian influenza and foot-and-mouth disease viruses. Sewage is removed by evaporation under high temperature, so soil and groundwater pollution caused by sewage can be avoided, and no foul smell is produced, which is convenient for later management of landfill sites. The decomposed carcasses can be used as fertilizer for forest trees or as compost for agriculture.

In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Preparation of Oxygen Nanobubble Water

Use a grinder to remove the outer skin of the bamboo to obtain the micropores of the bamboo. Afterwards, the bamboo was irradiated with 50 kGy gamma rays, and placed in an autoclave at 2 pressure and 80° C. to remove moisture and organic matter, so as to obtain a bamboo nano-bubble generating film. Finally, add high-concentration oxygen to the cylindrical bamboo nano-bubble generating membrane in water and apply a pressure of 2 bar to generate nano-bubbles, thereby preparing oxygen nano-bubble water.

[Example 1]

After burying the livestock and poultry carcasses, it was confirmed that the aerobic thermophilic microorganisms had been activated by the oxygen nanobubble water and the temperature had risen.

With 10kg (5kg×2) of chicken carcasses, 3kg of coarse bran, litter, sawdust, fallen leaves, hay and fully cooked compost mixture of coarse bran, 0.48kg of oxygen nano-bubble water and microbial preparations (natural love (company name), MICRO MAX Agricultural Association, Inc.) for mixing. The mixing ratio of the microbial agent and the chaff mixture was 1:36, and no oxygen was supplied from the outside within 48 hours.

Normal water was used instead of oxygen nanobubble water for mixing, and the outside air was delivered by a ring blower from the beginning as a control group. The temperature was measured after 24 hours and 48 hours respectively, and the degree of activity of the aerobic thermophilic microorganisms was confirmed. The temperature measurement results showed that the temperature of the oxygen nanobubble water group and the control group both rose to 60°C after 24 hours, and rose to 75°C after 48 hours (as shown in Figure 14). However, the temperature distribution in the buried box of the experimental group using oxygen nanobubble water is more uniform.

[Example 2]

To observe the degradation degree of livestock and poultry carcasses using oxygen nanobubble water. Microbial preparations (Natural Love (company name), MICRO MAX Agricultural Associates, Inc.) were mixed with a mixture of chaff, litter, sawdust, litter, hay and fully cooked compost, and oxygen in experimental landfill boxes that could be observed from the outside. Nanobubble water mixed well. The mixing ratio of microbial agent and coarse bran mixture is 1:36, and it is covered on the bottom of the box to form an active layer. Then, 10 kg of chicken carcasses, 0.48 kg of oxygen nano-bubble water, and microbial preparations were mixed evenly. The mixing ratio of microbial preparations and coarse bran mixture was 1:36, and covered on the active layer to form a corpse degradation layer. Then, the mixture of microbial preparation and coarse bran was mixed at a ratio of 1:36, and covered on the corpse degradation layer to form a deodorizing embedding layer. When using oxygen nano-bubble water, do not input oxygen from the outside within 48 hours.

Oxygen was delivered by a ring blower without using oxygen nanobubble water as a control group.

After 24 hours, it was determined that the temperature of the group using oxygen nanobubble water was 55°C, and the temperature of the group using ordinary water was 52°C (as shown in Figure 15). After 10 days, it was determined that the temperature of the group using oxygen nanobubble water was 42°C, and the temperature of the group using ordinary water was 47°C. Can't observe the livestock and poultry carcasses in a group of using oxygen nanobubble water from the outside, therefore think that the livestock and poultry carcasses of this group have been completely degraded (as Fig. 16). Excavate the degradation layer of the buried corpse to confirm the degree of degradation of the corpse. It has been confirmed that on the 10th day, the corpses of the group using ordinary water still had meat and bone residues (as shown in Figure 17(b)), but no residues were found in the group of oxygen nanobubble water (as shown in Figure 17(b)). a)); at 12 days, some residues of meat and bones can still be seen in the group using ordinary water (as shown in Figure 17(d)); at 15 days, the residues in the group using ordinary water have basically disappeared (as shown in Figure 17(f) ). It can be seen that the degradation rate of livestock and poultry carcasses in the group of oxygen nano-bubble water is faster. And after measuring, when 15 days, the moisture content of using the oxygen nano-bubble water group is about 40%, and the moisture content of using common water group is about 60%. This shows that compared with the normal water group, the activation degree and activation duration of the aerobic thermophilic microorganisms in the oxygen nanobubble water group are better (as shown in Figure 17).

[Example 3]

The bulk livestock and poultry corpse burying method of the present invention is implemented according to the following method.

The preparations required for burying 100 tons of livestock and poultry carcasses are shown in Table 1.

[Table 1]

Preparations for burying livestock and poultry carcasses (50,000 chickens weighing 2kg, specification: 100 tons of carcasses)

The production method of oxygen nano-bubble water is as follows:

Use a grinder to remove the outer skin of the bamboo to obtain the micropores of the bamboo. Then use 50kGy gamma rays to irradiate the bamboo, and place it in an autoclave at 2 pressure and 80° C. to remove moisture and organic matter, so as to obtain a bamboo nano-bubble generating film. Finally, the oxygen nano-bubble water was prepared by adding high-concentration oxygen and a pressure of 2 bar to the cylindrical bamboo nano-bubble generating membrane in water to generate nano-bubbles.

The methods of burial of livestock and poultry carcasses are as follows:

1. Select a burial site and build a burial pool

After selecting a site for burying livestock and poultry carcasses, build a burial pond with a standard size of 6m wide x 2.5m high x 23m long (345m ³ ). Then excavate the pit according to the same standard. The height of the buried pool is 2m underground and 0.5m above the ground, and there is a 0.5m wide earth embankment. The schematic diagram of the buried site excavation for the construction of the buried pool is shown in Figure 4. It is necessary to ensure that the bottom of the buried pond is flat, so that the oxygen nano-bubble water can be evenly supplied to the bottom during the degradation process of livestock and poultry carcasses. In order to cope with the leakage of sewage caused by the damage of the waterproof plastic film at the bottom of the buried pool, before laying the non-woven fabric, spray aerobic thermophilic microorganisms (16.7kg for a standard-sized buried pool) at a rate of 400g per ^3.3m2 to the standard The size of the bottom of the buried pool forms a soil purification layer.

Table 2 shows the types and quantities of livestock and poultry that can be treated in different sizes of landfill ponds.

[Table 2]

2. Laying waterproof membrane and waterproof membrane protective layer

The waterproof membrane uses double-layer plastic film, and the waterproof membrane protective layer uses non-woven fabric.

In order to protect the waterproof membrane, the bottom of the buried pool and the pool wall are all covered with non-woven fabrics with a thickness of not less than 7mm, and then covered with a double-layer waterproof plastic film with a thickness of not less than 0.1mm. The width of the plastic film should be at least 2m higher than the sum of the bottom and both sides of the buried pool, and completely cover the earth embankment outside the buried pool (as shown in Figure 5).

3. Install the porous air supply pipe

The porous air supply pipe uses a low-pressure dispersion rubber hose——Unibio hose (50m/roll), and lays 2 rows continuously on the waterproof plastic film along the length direction of the buried pool. The distance between adjacent Unibio hoses is not greater than 0.7m. And in order to ensure smooth air supply, they should not be intertwined or bent. Use the same method to lay 4 rolls of 8 Unibio hoses along the length of the buried pool according to the 6m width of the buried pool (as shown in Figure 6).

4. Connect the air distribution pipe and connecting pipe

The connecting pipe (XL pipe) is a rigid pipe made of PE material with an outer diameter of 20mm and a thickness of about 2mm. One end of the connecting pipe is connected to the Unibio hose and is perpendicular to the inner wall width of the buried pool. After installation, it is fixed with adhesive tape or adhesive, and positioning pins and other fixing tools that may damage the waterproof plastic film are not used. The air distribution pipe uses galvanized pipe, equipped with a 50mm reducing tee joint, a short socket joint and a 15mm elbow. After connecting with the connecting pipe, the air of the ring blower is distributed to the Unibio hose through 8 connecting pipes (Figure 7 and Figure 8)

5. Formation of the active layer

Evenly cover the installed Unibio hose with a mixture of aerobic thermophilic microorganisms, oxygen nanobubble water and coarse bran with a thickness of about 30 cm. The coarse bran mixture acts as a gas-permeable material to provide the oxygen nanobubble water with the moisture and voids required for the continuous activation of aerobic thermophilic microorganisms (Fig. 9).

6. Formation of corpse degradation layer

The livestock and poultry carcasses, aerobic thermophilic microorganisms, coarse bran mixture and oxygen nano-bubble water are uniformly mixed outside the landfill pond. The obtained mixture is laid in the buried pond in the shape of a bulge (∧) along the length direction of the buried pond to form a corpse degradation layer. Stacking in this shape facilitates water evaporation and heat preservation, which in turn facilitates the effective and continuous activation of aerobic thermophilic microorganisms. The middle part of the corpse-degradable layer is about 0.5m higher than the ground, so the air permeability can be improved (Fig. 10). The livestock and poultry carcass degradation layer can also treat farm pollutants and feed at the same time.

7. Formation of deodorization sealing layer

After mixing aerobic thermophilic microorganisms for deodorization, coarse bran mixture and oxygen nano-bubble water, the resulting mixture is completely covered on the corpse degradation layer, the covering thickness is not less than 0.5m, and the accumulation height is about 1m from the ground, forming a deodorization layer. Odorous sealing layer (Figure 11). The deodorizing sealing layer plays the role of preventing the livestock and poultry carcasses from being exposed to the outside and removing the stench generated in the early stage in the buried pond.

8. Build earth embankments around the buried pool

In order to prevent the intrusion of external pollutants and rainwater in the buried pool, an earth embankment with a height and thickness not less than 0.5m above the ground is built.

9. Construction of drainage pipes and external storage tanks around the embankment

Build a drainage pipeline with a height of not less than 0.3m outside the earth embankment, and pile up an earth embankment with a height of not less than 0.3m around the drainage pipeline to smoothly drain the rainwater that falls on the rain-shielding film. One end of the drainage pipeline shall be built with a storage tank with a size not less than 0.5m ³ for collecting rainwater. Choose to connect to the storage tank in the direction of the lower slope.

10. Connect the air distribution pipe and ring blower

Connect the connecting pipe with the air distribution pipe and the ring blower (Fig. 12).

11. Laying shading film

In order to prevent the loss of the deodorizing embedding layer caused by external factors and cut off the intrusion of external pollutants, the surface of the deodorizing embedding layer is covered with a light-shielding film with a shading rate of not less than 95%. The edge of the light-shielding film is fixed with positioning pins.

12. Laying rain-shielding film

Lay a rain-shielding film with a height of not less than 1m in the form of a plastic greenhouse on the surface of the deodorizing embedding layer. The frame of the rain-shielding film uses metal steel pipes for agricultural plastic greenhouses with an outer diameter of 25mm, a thickness of 1.5mm, and a length of 9m. The rain-shielding film is laid according to the ∩ shape to keep a certain distance from the deodorizing embedding layer. The skeleton of the rain-shielding film is built outside the drainage channel at a distance of 80 cm along the length of the buried pool, and the internal distance between it and the deodorizing buried layer is kept below 0.1 mm. In order to prevent rainwater from directly falling onto the deodorizing sealing layer, cover the skeleton of the rain-shielding film with a transparent plastic film with a thickness of not less than 0.1mm and fix it. The distance between the transparent plastic film and the ground is about 50cm, the purpose is to maintain air permeability (Figure 13). While laying the rain-shielding film, install a thermometer with a sensing rod no less than 50cm on the edge of the buried pool, so as to directly identify the degree of degradation of the corpse through temperature. After laying the rain-shielding film, set up warning signs.

13. Start the ring blower

After the installation of the livestock and poultry carcass processing equipment is completed, the ring blower does not need to be started for the first 48 hours. After 48 hours, start the annular blower. During the first 3 months of operation, stop the operation 4 times a day, each time for 15 minutes, and continue to run for the rest of the time; after 3 months, run for 8 hours a day.

14. Detection of whether the management of the burial site is over and whether the livestock and poultry carcasses are completely degraded

Five months after the installation of the livestock and poultry carcasses processing equipment, we will carry out detailed inspections on whether there are residual avian influenza and foot-and-mouth disease bacteria, so as to decide whether to end the management of the burial site. Take a soil sample of 1/3 of the conical tube from the degraded soil of livestock and poultry carcasses at a depth of 60cm from the upper layer of the burial pool. After the conical tube is sterilized, detect Bacillus anthracis, avian influenza and foot-and-mouth disease bacteria. The test results showed that the bacteria of avian influenza and foot-and-mouth disease were negative, and then the degree of degradation of the corpse was observed. After it is finally confirmed that the bones of the livestock and poultry carcasses have been completely decomposed, the management of the landfill pond will be terminated.
