Abstract
The utility model discloses a sewage biochemical treatment system, including grid, pH equalizing basin, high load capacity depositing reservoir and bio -aeration filtering pond, grid, pH equalizing basin, high load capacity depositing reservoir and bio -aeration filtering pond connect gradually, the pH equalizing basin passes through during the elevator pump goes into the high load capacity depositing reservoir with the waste water pump, a sedimentation tank is connected in the bio -aeration filtering pond, the bottom in bio -aeration filtering pond is connected to sedimentation tank bottom, flows back in the bio -aeration filtering pond further the processing again with the mud in the sedimentation tank. The utility model discloses mud in the sedimentation tank bio -aeration filtering pond of can flowing back once more, the circulation is handled, has reduced the emission of mud.
Description
Technical field
The utility model relates to sewage treatment area, especially a kind of biochemical wastewater treatment system.
Background technology
Sewage disposal is the significant process of process water pollutions, physics, biology and chemical process is adopted to process trade effluent and sanitary sewage, with the solid pollutant in Separation of Water and the organic pollutant reduced in water and nutrient rich, thus alleviate the pollution of water to environment.
Biochemical process utilizes biological action, makes in waste water in dissolve and the organic pollutant of colloidal state is converted into harmless material.Conveniently, so be one of process important in Waste Water Treatment, at present, the method has been widely used in the second-stage treatment of the industrial organic waste water of sanitary sewage and easily degraded for the method low cost, operational management.Wherein, conventional carrier is BAF, but the shortcoming of BAF to be sludge yield large, and the poor stability of mud.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of biochemical wastewater treatment system, mud can be carried out circular treatment, thus reduces the final quantity discharged of mud.
For achieving the above object, the technical solution adopted in the utility model is: a kind of biochemical wastewater treatment system, comprise grid, pH regulator pond, high-load settling tank and biological aerated filter, described grid, pH regulator pond, high-load settling tank are connected successively with biological aerated filter, waste water pumps in high-load settling tank by lift pump by described pH regulator pond, described biological aerated filter connects a settling tank, the bottom of biological aerated filter is connected bottom described settling tank, mud in settling tank is back in biological aerated filter again, processes further.
Described biological aerated filter is provided with aerating apparatus, and described aerating apparatus is connected with gas blower, and wherein, aerating apparatus is micropore aeration pipe.
Be provided with back flushing water inlet pipe and back flushing inlet pipe bottom described biological aerated filter, back flushing water inlet pipe and back flushing inlet pipe pipeline are respectively equipped with water intaking valve and intake valve, and described water intaking valve is all connected with automatic control system with intake valve.
Described settling tank connects filtering basin, and described filtering basin connect the water inlet pipe in pH regulator pond, uses for the clear liquor on filtering basin upper strata being back to pH regulator pond internal recycle.
The beneficial effects of the utility model are: the utility model adopts high composite clarification pond to combine with biological aerated filter, high composite clarification pond can not only realize the sludge condensation of certain degree, very high hydraulic load can also be realized, improve processing efficiency, reduce capital construction and drop into; Adopt upward flowing type biological aerated filter, sewage to be processed and pressurized air are all directed to bottom filter tank, can avoid falling the formation of surface blocking and the air bag often occurred in streaming filter tank; In addition, only there is the water outlet after process to be just exposed in air, stink can be reduced to greatest extent, more environmental protection.Mud in settling tank can be back to biological aerated filter again, circular treatment, decreases the quantity discharged of mud.
