Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is not to uniformly treat the treatment of sewage and wastewater discharged from households, but to separate a high concentration treatment tank and a low concentration treatment tank that perform separation treatment according to the level of pollutant concentration. In particular, the present invention relates to a hybrid processing tank that is hybridized by being integrated and integrated, and particularly relates to a hybrid processing tank that can cope with a disposer that has recently become widespread.
[0002]
[Prior art]
With the advancement of wastewater treatment technology, a single septic tank that purifies human wastewater is abolished, and toilet wastewater discharged from households, kitchen wastewater, bathroom wastewater, laundry wastewater, toilet wastewater, and other household wastewater are all combined. It is uniformly purified by the septic tank.
[0003]
At that time, in particular, in order to enable merger processing for bathroom wastewater and laundry wastewater that flows out at a peak of 200 to 300 L / day, it is inevitably necessary to have a combined treatment septic tank with a large capacity. .
[0004]
By the way, when focusing on the pollutant concentration in the sewage drainage that is subject to the merger process, in the case of toilet sewage, kitchen drainage, etc., the pollutant concentration belongs to a very high category. It is well known that in the case of bathroom drainage, laundry drainage, bathroom drainage, etc., the degree of dirt belongs to a very low category.
[0005]
[Problem 1 to be Solved by the Invention]
In the conventional combined treatment septic tank, the concentration of pollutants in the sewage drainage is not taken into account, and the boulders are mixed and used uniformly for the combined purification treatment. It is efficient.
[0006]
For example, the purification capacity of organic sewage with extremely high pollutant concentration is easily diluted by bathroom effluent or laundry effluent that flows in a large amount in a short period of time, and this causes processing spots.
[0007]
Therefore, in order to reduce the influence of a large amount of inflow and secure a predetermined discharge performance, various devices such as incorporating a flow rate adjusting tank and its auxiliary device, and enabling the flow rate adjustment in the entire tank are added. As a result, the merger processing septic tank is increased in capacity.
[0008]
On the other hand, for bathroom drainage, laundry drainage, bathroom drainage, etc. with a low degree of contamination, the degree of contamination is relatively increased by mixing with organic wastewater with a high concentration of contaminants.
[0009]
In the conventional merger treatment septic tank, wastewater with a low degree of contamination is treated as a non-recyclable treatment method such as toilet wash water, car wash water, garden water sprinkling water, etc. It is also a situation where it is not possible to meet today's issues that require effective use of water.
[0010]
In this regard, conventionally, there is a case where a dedicated wastewater treatment tank for treating miscellaneous wastewater such as bathroom wastewater or rainwater as middle water is installed separately from the sewer.
[0011]
However, in the septic tank area where there is no sewerage facility, it is necessary to separately install the miscellaneous wastewater treatment tank in addition to the existing single septic tank or the combined treatment septic tank.
Then, in addition to forcing the users to increase the burden of equipment and maintenance costs, and considering the housing situation in Japan, the combined treatment septic tank and miscellaneous wastewater treatment tank 2 in the limited installation space There are many situations where it is difficult to install or bury tanks.
[0012]
Therefore, in order to solve the above-mentioned problems, in the specification of Japanese Patent Application No. 11-32153 and its drawings relating to the prior application, a sewage treatment tank for purifying sewage having a high pollutant concentration, and a pollutant concentration As a result, a hybrid septic tank is obtained by combining a wastewater treatment tank that regenerates low-level wastewater into a single tank.
[0013]
More specifically, in a single tank, a high-concentration sewage treatment tank that purifies toilet sewage and kitchen effluent with a high concentration of pollutants, and bathroom drainage and laundry that have a relatively low degree of contamination among household wastewater. We provide a hybrid septic tank that incorporates a low-concentration wastewater treatment tank that recycles wastewater and toilet drainage, etc., as toilet washing water, car washing water, garden watering water, etc.
[0014]
On the other hand, recently, a disposer has been built directly under the drain of the kitchen sink (sink), so that vegetable scraps, fish bones, heads, etc. generated in the kitchen, or food waste that has expired or has been left uneaten. Etc. are put on the rotating disc inside the disposer from the drain port, and the rotating disc is rotated at a high speed by an electric motor, so that the fixed blade with irregularities formed on the inner periphery of the disposer and the hammer blade provided on the rotating disc After being finely pulverized, it is washed with wastewater (hereinafter referred to as garbage wastewater).
[0015]
This prevents the generation of bad odors and insects caused by storing raw garbage in and out of the kitchen until it is recovered, reducing the amount of waste, and in particular, taking out garbage on specified days of the week, hours, etc. This reduces the burden on residents who are restricted by conditions.
[0016]
[Problem 2 to be Solved by the Invention]
However, as a demerit when using a disposer, it increases the load of sewage treatment in sewers and septic tanks, and drains the shredded garbage, resulting in a significant increase in water usage.
[0017]
In other words, when the disposer is used, the waste garbage that is usually stored as garbage and collected and discarded is all shredded and discharged as garbage wastewater.
As a result, disposing of SS, such as shredded vegetable scraps, requires a great deal of cost to create a sewage treatment facility that can handle sewage pipes and high loads. There are many sewerage areas where use is not permitted.
[0018]
Similarly, when sewage treatment is performed using a septic tank, a larger treatment tank and a highly functional treatment tank are required to cope with the increased load.
In addition, since extra water is needed to drain the crushed garbage, the use of water may be prohibited in areas where water shortages are a concern because of water saving.
[0019]
Therefore, in the present invention, based on the hybrid treatment tank described in the specification and drawings of Japanese Patent Application No. 11-321153 relating to its prior application, the sewage treatment tank therein is a disposer-compatible type, He focused on dealing with the spread.
[0020]
Specifically, in claim 1, a single tank is mainly treated with a partition plate to mainly clean toilet wastewater, wastewater shredded by a disposer, and wastewater with a high concentration of pollutants such as kitchen wastewater. High-concentration sewage treatment tanks and mainly low-concentration wastewater treatment tanks that regenerate wastewater with low pollutant concentration, such as bathroom drainage, laundry wastewater, and wash drainage, into middle water. The sewage treatment tank is divided into a primary treatment tank for the inflowing sewage drainage, a secondary treatment tank for the primary treatment water, a treatment water tank for the secondary treatment water, and a disinfection tank for the sewage drain, and the other low concentration The wastewater treatment tank is separated by a partition into a primary treatment tank for inflowing wastewater, a secondary treatment tank for the primary treated water, a treated water tank for the secondary treated water, a disinfection tank, or a disinfection tank, and disinfected treatment water. The water tank is further divided into sterilization tanks for low-concentration wastewater treatment tanks. Disposer characterized in that the reservoir is at the full level, to constitute a waste water flowing into the primary treatment tank of the low-concentration wastewater treatment tank, so as to flow in the overflow to the primary treatment tank of the high-concentration sewage treatment tank Providing compatible hybrid processing tanks.
[0021]
Therefore, the sewage treatment tank of the hybrid septic tank in the septic tank area is mainly characterized by purifying sewage effluent with high pollutant concentration such as toilet sewage, garbage waste shredded by a disposer, and normal kitchen effluent. To do.
[0022]
Further, in claim 2, a high-concentration wastewater treatment tank for purifying wastewater having a high concentration of pollutants such as garbage wastewater and kitchen wastewater shredded by a disposer mainly in a single tank by a partition plate; , Mainly, it is divided into low-concentration wastewater treatment tank that regenerates wastewater with low pollutant concentration such as bathroom drainage, laundry wastewater, and wash drainage into middle water, and one of the high-concentration wastewater treatment tanks is separated by a partition wall. The primary treatment tank for the inflowing sewage wastewater, the secondary treatment tank for the primary treatment water, the treatment water tank for the secondary treatment water, and the disinfection tank, and the other low-concentration wastewater treatment tank by the partition wall, Dividing into a primary treatment tank of inflowing wastewater, a secondary treatment tank of the primary treated water, a treated water tank of the secondary treated water, a disinfection tank or disinfection tank thereof, and a storage tank of disinfected treatment water, In addition, the disinfection tank or storage tank of the low-concentration wastewater treatment tank is full. It came to the wastewater flowing into the low-concentration wastewater treatment tank primary treatment tank, to provide a disposer corresponding hybrid treatment tank, characterized by being configured so as to discharge in the overflow to the sewer.
[0023]
In short, in the sewer area, toilet sewage is discharged into the sewer pipe as it is for treatment at the sewage facility, and wastewater with high pollutant concentration (such as toilet wastewater) Is not treated) in a high-concentration wastewater treatment tank, so that the disposer can be widely used.
[0024]
Therefore, in order to reduce the burden on sewerage and sewage treatment facilities, in the case of sewerage areas, the problem of increased load resulting from the use of the disposer by using the hybrid treatment tank as described above. This is solved by a high-concentration wastewater treatment tank that treats garbage wastewater and kitchen wastewater that does not include toilet wastewater. In the case of the septic tank area, high-concentration wastewater treatment of garbage wastewater and kitchen wastewater including toilet wastewater In the tank, it can be handled by purifying it to the same level as a normal septic tank and discharging it. In addition, by having a “low-concentration wastewater treatment tank for the use of medium water”, it promotes the reuse of water and solves the problem of increased water consumption.
[0025]
At that time, by a partition plate a single tank, by partitioning a high concentration sewage treatment tank or the high-concentration waste water treatment tank and a low-concentration wastewater treatment tank, toilet cleaning water, wash water, watering water etc. garden A low-concentration wastewater treatment tank for reuse as intermediate water is prevented from being contaminated by high-concentration sewage treatment tank or sewage drainage flowing into the high-concentration wastewater treatment tank.
[0026]
In addition, when the sterilization tank or storage tank of the low-concentration wastewater treatment tank is full, wastewater (surplus) flowing into the primary treatment tank of the low-concentration wastewater treatment tank is replaced with a high-concentration sewage treatment tank in the septic tank area. By making it flow into the primary treatment tank by overflow, the surplus portion of the influent wastewater is used for merged treatment with sewage wastewater with a high concentration of pollutants , and in the sewer area, it is discharged to the sewer by overflow .
[0027]
Further, in claim 3, by incorporating a means for pumping up the middle water sterilized in the low-concentration waste water treatment tank from the sterilization tank or the water storage tank, the middle water is usually discharged from the hybrid treatment tank buried in the ground. It is convenient to pick up and reuse.
[0029]
DETAILED DESCRIPTION OF THE INVENTION
1 is a schematic plan view of a hybrid treatment tank shown in FIG. 1, and a first example and a first example of a disposer-compatible hybrid treatment tank installed in a septic tank area shown in FIG. 2 and FIG. Based on the schematic flow of the two examples of water supply and drainage and the schematic flow of the first and second examples of the hybrid treatment tank for the disposer type installed in the sewerage area where the toilet drainage shown in FIGS. I will explain.
[0030]
1 is a partition plate that completely separates a single tank into two tanks, one side of which has a large capacity is partitioned into a high-concentration sewage treatment tank X that purifies sewage drainage with a high pollutant concentration, The other side with the smaller tank capacity is partitioned into a low-concentration wastewater treatment tank Y that regenerates wastewater with a low pollutant concentration.
[0031]
The capacity ratio of each tank is equal to the number of target personnel, the septic tank of the water supply / drainage system shown in FIG. 2 or 3 in which the toilet drainage is purified in the high-concentration sewage treatment tank of the hybrid treatment tank, or the toilet sewage is passed to the sewer Normally, the tank capacity of the high-concentration sewage treatment tank X containing toilet sewage (or high-concentration effluent treatment tank not containing toilet sewage) is 2/3 of the whole, although it depends on whether the water supply / drainage system shown in FIGS. About 3/4, the low concentration waste water treatment tank Y is about 1/3 to 1/4.
[0032]
Among them, one high-concentration sewage treatment tank X is divided into a plurality of treatment tanks from the inflow pipe 2 side into which high-concentration sewage drainage flows into the treated water discharge pipe 3 side according to the sewage treatment process order. Specifically, a primary treatment tank 4 for anaerobically treating the inflowing sewage waste water, a secondary treatment tank 5 for aerobically treating the primary treated water, a treated water tank 6 for storing the secondary treated water, and And a disinfection tank 7 for disinfecting.
[0033]
In the case of the septic tank area shown in FIG. 2 and FIG. 3 as the target to be purified in this high-concentration sewage treatment tank X, toilet sewage, normal kitchen drainage, garbage wastewater shredded by a disposer and discharged by water, etc. Of high concentration sewage drainage.
In the case of the sewer area shown in FIGS. 4 and 5, high-concentration wastewater such as garbage wastewater not including toilet wastewater and normal kitchen wastewater is targeted.
Therefore, a wastewater treatment tank that does not include toilet wastewater and is treated as high-concentration wastewater treatment tank X, which is intended for garbage wastewater, kitchen wastewater, and the like having a high concentration of pollutants.
[0034]
In FIG. 1, reference numeral 8 denotes a partition wall between the primary treatment tank 4 and the secondary treatment tank 5, and primary treatment water is transferred from the transfer port provided in the partition wall 8 to the secondary treatment tank 5.
Reference numeral 9 denotes a partition wall between the secondary treatment tank 5 and the treated water tank 6, and the secondary treated water flows through the bottom opening of the partition wall 9 and is transferred to the treated water tank 6.
Reference numeral 11 denotes a partition wall between the treatment water tank 6 and the disinfection tank 7, and the supernatant liquid stored in the treatment water tank 6 flows into the disinfection tank 7 and is used for disinfection treatment.
[0035]
The other low-concentration wastewater treatment tank Y is divided into a plurality of treatment tanks according to the order of the wastewater regeneration treatment process from the inflow pipe 11 side where the wastewater flows to the advection pipe 12 side of the treated water. Is a primary treatment tank 13 for inflowing wastewater, a secondary treatment tank 14 for the primary treated water, a treated water tank 15 for the secondary treated water, a disinfection tank 16 for disinfecting the treated water, and a disinfected middle water. Water tank 17.
[0036]
The wastewater treatment tank Y can be treated in any wastewater wastewater shown in FIGS. 2 to 5, such as bathroom sewage with low pollutant concentration, laundry wastewater, wash drainage, etc., regardless of septic tank area or sewer area. Concentrated wastewater is targeted.
[0037]
In the case of the waste water treatment tank Y, as in the case of the sewage treatment tank X, the treatment tanks 13 to 17 are partitioned by the partition walls 18 to 21 as shown in FIG.
Among them, the primary treatment tank 13 and the secondary treatment tank 14 are partitioned by the partition wall 18, and the secondary treatment tank 14, the treated water tank 15, and the disinfection tank 16 are partitioned by the partition wall 19.
Moreover, the treated water tank 16 and the disinfection tank 16 are partitioned by the partition wall 20, and the treated water tank 15, the disinfection tank 16 and the water storage tank 17 are partitioned by the partition wall 21.
[0038]
Reference numeral 22 denotes a pump for pumping up the middle water of the water storage tank 17. As shown in FIG. 1, the pump 22 is installed in the water storage tank 17 or provided in the middle of the water supply pipe 23 connected to the advection pipe 12. It is done.
The middle water pipe 23 is piped indoors and outdoors in order to reuse the middle water pumped up by the pump 22 as toilet washing water, car washing water, garden tree watering water, and the like.
[0039]
Reference numerals 24 and 25 are advection pipes and their check valves, which are provided above the partition plate 1 that partitions the primary treatment tank 13 of the wastewater treatment tank Y and the primary treatment tank 4 of the sewage treatment tank X. The excess drainage that has flowed into the wastewater treatment tank X is overflowed into the primary treatment tank 4, and the check valve 25 prevents backflow.
Naturally, since the water level line of the primary treatment tank 13 on the waste water treatment tank Y side is set to be higher than the water level line of the primary treatment tank 4 on the sewage treatment tank X side, The check valve 25 is not necessary, but it is preferable to attach it for the sake of safety.
[0040]
[Modification]
In FIG. 1, reference numeral 26 denotes a bypass pipe, and as shown by an imaginary line, the surplus portion of the inflow wastewater to the wastewater treatment tank Y is bypassed from the middle of the drainage inflow pipe 11 to the sewage inflow pipe 2. Piping to advection.
Therefore, as a means for flowing the surplus waste water into the primary treatment tank 4 of the sewage treatment tank X, it overflows directly from the advection pipe 24 provided in the tank or flows in from the bypass pipe 25 piped outside the tank. To deal with either.
[0041]
Thus, when high-concentration sewage effluent such as toilet sewage, kitchen effluent, and garbage effluent flows into the primary treatment tank 4 from the sewage inflow pipe 2, the contaminants in the sewage are removed before the primary treatment tank 4. It removes by carrying out precipitation separation, or after anaerobic treatment in the 1st chamber of an anaerobic filter bed tank, it is anaerobic-treated again in an anaerobic filter bed tank of the back | latter stage, and a primary process is made | formed.
[0042]
When the primary treated water is transferred to the next secondary treatment tank 5, it is usually subjected to biological filtration treatment through the fluidized bed carrier by the air blown from the diffuser, or aeration treatment using the contact filter medium, or Purification is performed by dynamic filtration using a nonwoven membrane module immersed in activated sludge in the tank, or by suction filtration using a precision flat membrane module and a suction pump.
[0043]
Thereafter, the secondary treated water is diverted and stored from the partition wall 9 to the next treated water tank 6, subjected to the disinfection treatment in the disinfection tank 7, and then discharged outside the tank.
[0044]
On the other hand, when low-concentration wastewater such as bathroom wastewater, laundry wastewater, and wash drainage flows into the primary treatment tank 13 from the daily wastewater, the primary treatment tank 13 precipitates impurities in the wastewater. It removes by separating, or it removes with a screen etc. and performs a primary process.
[0045]
When this primary treated water is transferred to the next secondary treatment tank 14, it is usually subjected to biological filtration treatment with a jet of air from a diffuser through a fluidized bed carrier, aeration treatment with a contact filter medium, or It is regenerated into reclaimed water that can be reused by dynamic filtration with a nonwoven membrane module immersed in the tank or suction filtration with a precision flat membrane module and a suction pump.
[0046]
Further, the filtered treated water is transferred to the next treated water tank 15 and stored as necessary, and then subjected to the disinfection treatment in the disinfecting tank 16.
The sterilized middle water is finally transferred to and stored in the water storage tank 17, pumped up by a pump 22 provided inside or outside the tank, and supplied to the water supply pipe 23 for reuse. Is done.
[0047]
[Modification]
If the secondary treatment tank 14 of the waste water treatment tank Y is a membrane treatment tank, the filtered water can be directly transferred to the disinfection tank 16.
When the water storage tank 17 is installed alone outdoors, the advection pipe 12 is connected to the disinfection tank 16 and pumped up to an outdoor water storage tank (not shown).
[0048]
【The invention's effect】
As described above, the present invention is a high-concentration sewage treatment tank targeting garbage waste water and toilet sewage shredded by a disposer, or a high-concentration waste water treatment tank targeting garbage waste water and kitchen waste water. Since the low-concentration wastewater treatment tank that treats wastewater with low pollutant concentration is integrated into a single tank, it is a hybrid treatment tank that is compatible with the disposer. Treatment and treatment of low-concentration wastewater as middle water can be performed appropriately and extremely efficiently.
[0049]
Therefore, in the case of sewerage areas, the problem of increased processing load resulting from the use of disposers is to reduce the burden on sewerage and sewage treatment facilities. This is solved by a high-concentration wastewater treatment tank that treats wastewater, etc. In the case of a septic tank area, garbage wastewater including kitchen wastewater, kitchen wastewater, etc. are purified to the same level as a normal septic tank in a high-concentration sewage treatment tank. By disposing and discharging, it is possible to deal with the spread of disposers.
[0050]
Moreover, since a low-concentration wastewater treatment tank for using middle water is incorporated, the reuse of water is promoted, and the problem of increased water usage is also solved.
Specifically, the other low-concentration wastewater treatment tank is used to remove bathroom wastewater, laundry wastewater, wash water drainage, etc., which have a relatively low level of contamination, from toilet cleaning water, car wash water, and garden water spray water. It can be reused as middle water, etc., and exerts tremendous effects such as saving water and contributing to effective use of water resources.
[0051]
At that time, by a partition plate a single tank, by partitioning a high concentration sewage treatment tank or the high-concentration waste water treatment tank and a low-concentration wastewater treatment tank, toilet cleaning water, wash water, watering water etc. Niwaki A low-concentration wastewater treatment tank to be reused as middle water is not contaminated by inflow sewage from a high-concentration sewage treatment tank or wastewater from a high-concentration wastewater treatment tank.
[0052]
In addition, when the disinfection tank or storage tank of the low-concentration wastewater treatment tank is full, wastewater (surplus) flowing into the primary treatment tank of the low-concentration wastewater treatment tank is transferred to the primary treatment tank of the high-concentration wastewater treatment tank. By making it flow in by overflow, the surplus portion of the influent wastewater is subjected to merger processing with sewage wastewater having a high pollutant concentration.
Therefore, the processing of the surplus inflow wastewater when the water tank becomes full is not impaired.
[0053]
In addition, by incorporating a means to pump up the sterilized water in the low-concentration wastewater treatment tank from the sterilization tank or water storage tank, the water is usually drawn up from the hybrid treatment tank buried in the ground and reused. To be convenient.
