Abstract
The invention provides a building rubbish treating method. The building rubbish treating method comprises the following steps: firstly, collecting and smashing building rubbish, and sorting out large steel; then separating and recovering light rubbish through a vibrating screen, and carrying out next operation on the remaining heavy rubbish; and finally, smashing the heavy rubbish obtained from the step to be below 100mm for recovering. According to the method, the building rubbish pollution problem can be effectively solved, the existing building rubbish can be decreased, and the effect of improving the environment can be achieved; and rubbish can be changed into wealth to be entirely recycled, thereby creating good economic values.
Description
Technical field
The invention belongs to the solid waste process field, be specifically related to the processing method of building waste.
Background technology
Along with the quickening of urban construction paces, the replacement speed of new and old buildings thing is also being accelerated.The Urban Large scale construction makes building waste more and more, and the phenomenon of arbitrarily banking up is also more and more serious, and managerial problem highlights just day by day.We are enjoying good days simultaneously, and building waste is but at the environment that corrodes stealthily us; We embrace modern architecture and bring our all, and building waste has brought the difficult problem of environmental protection but for our body.
The quantity of China's building waste has accounted for 30% ~ 40% of municipal refuse total amount.According to the rough Statistics of the construction material loss that brick mix structure, full cast-in-place structural and frame structure etc. are built, in the work progress of per ten thousand square meters building, only building waste will produce 500 ~ 600 tons; And the old building of per ten thousand square metres of dismountings will produce 7000 ~ 12000 tons of building wastes, and the old building of the annual demolition of China accounts for 40% of building total amount.
At present, unprocessed namely being connect of most building wastes transports the suburb stacking to, taken a large amount of industrial lands, and as being located in reason not as good as timeliness and utilizing, the contradiction of its appropriation of land can be more and more serious.In addition, building waste is after stacking a process rainwater sprinkling, the a large amount of afwillites and the calcium hydroxide that contain in waste mortar and the concrete block, the a large amount of sulfate ions that contain in the waste gypsum, the plurality of heavy metal ion stripping that contains in the old metal, anaerobic degradation generation lignin and tannic acid occurs and resolves into organic acid in waste paperboard and culled wood self simultaneously, and the leakage water that produces so generally is strong basicity and contains a large amount of heavy metal ion, hydrogen sulfide and a certain amount of organic matter flow into Jiang Hai as not adding control, lake or the end, infiltration ground, can cause earth's surface and underground water pollution directly to endanger aquatic organism existence and water resource utilization.Moreover, waste gypsum in the building waste contains a large amount of sulfate ions, under anaerobic can be converted into the hydrogen sulfide gas with rotten-egg odour, anaerobic degradation occurs and produces lignin and tannic acid and resolve into organic acid in waste paperboard and culled wood self, and these pernicious gases can the severe contamination atmosphere.The harmful substance of the above-mentioned generation of contaminated soil produces soil to be polluted, and affects nutrient absorption and the growth of plant, the ecological balance of spoiled soil inside.Therefore, the processing of building waste is very urgent.
Summary of the invention
The object of the present invention is to provide the innoxious recovery and treatment method of a kind of building waste, under the building waste prerequisite free from environmental pollution it is recycled guaranteeing.
For achieving the above object, the present invention adopts following technical scheme:
The building waste processing method may further comprise the steps:
(1) fragmentation: will carry out break process after the building waste collection, and sort out large shape;
(2) screening: separate the recovery light refuse by vibrosieve, residue heavy rubbish continues next step operation;
(3) pulverize: the heavy garbage crushing that step (2) is obtained is recycled to 100mm.
In the technical scheme provided by the invention, further, the large shape that step (1) reclaims melts down recycling.
In the technical scheme provided by the invention, further, the described light refuse of step (2) comprises timber, pottery, glass, plastics; Wherein, timber reclaims and is used for fuel; After all the other light refuse meltings as the roadbed raw material.
In the technical scheme provided by the invention, further, the heavy rubbish after the described pulverizing of step (3) is recycling as building material.
Method provided by the invention can effectively solve the building waste pollution problem, reduces existing building waste, has reached the effect of improving environment; And building waste is turned waste into wealth, and it is recycling all to turn one's head, and has created good economic worth.
The specific embodiment
The following examples can make the present invention of those of ordinary skill in the art's comprehend, but do not limit the present invention in any way.
Embodiment 1
The building waste processing method is characterized in that may further comprise the steps:
(1) fragmentation: with carrying out break process after the building waste collection, steel are separated with concrete, sort out large shape;
(2) screening: separate the recovery light refuse by vibrosieve, comprise paper material, timber, pottery, glass, plastics etc., residue heavy rubbish continues next step operation;
(3) pulverize: the heavy garbage crushing that step (2) is obtained is recycled to 100mm; Heavy rubbish is mainly concrete, brick and tile, stone material etc.
In the present embodiment, further, the large shape that step (1) reclaims melts down recycling.
In the present embodiment, further, in the described light refuse of step (2), timber reclaims and is used for fuel; After all the other light refuse meltings as the roadbed raw material.
In the technical scheme provided by the invention, further, the heavy rubbish after the described pulverizing of step (3) is recycling as building material.
Claims (4)
1. building waste processing method is characterized in that may further comprise the steps:
(1) fragmentation: will carry out break process after the building waste collection, and sort out large shape;
(2) screening: separate the recovery light refuse by vibrosieve, residue heavy rubbish continues next step operation;
(3) pulverize: the heavy garbage crushing that step (2) is obtained is recycled to 100mm.
2. method according to claim 1 is characterized in that: the large shape that step (1) reclaims melts down utilization.
3. method according to claim 1, it is characterized in that: the described light refuse of step (2) comprises timber, pottery, glass, plastics; Wherein, timber reclaims and is used for fuel; After all the other light refuse meltings as the roadbed raw material.
