Description
Technical field
This utility model relates to technical field of environment protection equipment, particularly one way of life sewage disposal system.
Background technology
Improving constantly of people's living standard, mankind's water consumption is the most increasing, and sanitary sewage also gets more and more, if sewage
The most treated being just discharged into nature, will necessarily pollute naturally producing, the most appropriate process sewage has become as pass
The problem being tied to descendants's existence.Existing sanitary sewage disposal, some employings compare the physical method of labor intensive material resources,
Some employing sewage-treating agents carry out chemical treatment, but relatively costly, and treatment effect is the most not fully up to expectations.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that domestic sewage processing system.
The purpose of this utility model is achieved through the following technical solutions: domestic sewage processing system, including passing through pipeline
Filtering grid, preliminary sedimentation regulating reservoir, anoxia filter tank, dephosphorization filter tank, aerobic filter tank, biofilter and the sterilization pool being sequentially connected with；Institute
The aerobic filter tank stated connects anoxia filter tank also by return duct, and return duct is provided with reflux pump.
Entering preliminary sedimentation regulating reservoir after filtering grid, preliminary sedimentation regulating reservoir front end sets settling zone, is removed in sewage by precipitation
Partial suspended thing and sand grains, regulating reservoir regulates (by aerobic filter tank mixed-liquor return to regulating reservoir) boosted pump after homogenizing
Entering anoxia filter tank and carry out denitrification, then gravity flow enters dephosphorization filter tank, sewage is by the phosphorus in sewage during dephosphorization filtrate and dephosphorization
Chemical substance in filtrate is reacted and is removed, and sewage flows automatically and enters aerobic filter tank, main organics removal (COD, BOD)
And ammonia nitrogen is carried out nitration reaction, for carrying out denitrification, mixed-liquor return is to regulating reservoir.The sterilized rear qualified discharge of water outlet.
Periodically each filter tank being carried out air backwash, after backwash, the sewage gravity in filter tank drains into preliminary sedimentation regulating reservoir precipitating phase, and bottom deposits
Mud periodically transport outward disposal.
Also include controller, in described aerobic filter tank, be provided with water quality detecting device, water monitoring device and reflux pump
All it is electrically connected with the controller.
This utility model has the advantage that
This utility model can effectively process sanitary sewage, and low cost is effective, alleviates the sanitary sewage dirt to ecological environment
Dye, wastewater suspended substance clearance reaches 98.3%, and BOD clearance is 95.2%, and COD clearance is 96.8%.There is purification speed
Hurry up, effective, the advantage such as environment-protecting asepsis.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
As it is shown in figure 1, domestic sewage processing system, including the filtering grid being sequentially connected with by pipeline, preliminary sedimentation regulating reservoir,
Anoxia filter tank, dephosphorization filter tank, aerobic filter tank, biofilter and sterilization pool；Described aerobic filter tank connects also by return duct and lacks
Oxygen filter tank, return duct is provided with reflux pump.
Entering preliminary sedimentation regulating reservoir after filtering grid, preliminary sedimentation regulating reservoir front end sets settling zone, is removed in sewage by precipitation
Partial suspended thing and sand grains, regulating reservoir regulates (by aerobic filter tank mixed-liquor return to regulating reservoir) boosted pump after homogenizing
Entering anoxia filter tank and carry out denitrification, then gravity flow enters dephosphorization filter tank, sewage is by the phosphorus in sewage during dephosphorization filtrate and dephosphorization
Chemical substance in filtrate is reacted and is removed, and sewage flows automatically and enters aerobic filter tank, main organics removal (COD, BOD)
And ammonia nitrogen is carried out nitration reaction, for carrying out denitrification, mixed-liquor return is to regulating reservoir.The sterilized rear qualified discharge of water outlet.
Periodically each filter tank being carried out air backwash, after backwash, the sewage gravity in filter tank drains into preliminary sedimentation regulating reservoir precipitating phase, and bottom deposits
Mud periodically transport outward disposal.
Also include controller, in described aerobic filter tank, be provided with water quality detecting device, water monitoring device and reflux pump
All it is electrically connected with the controller.
This utility model can effectively process sanitary sewage, and low cost is effective, alleviates the sanitary sewage dirt to ecological environment
Dye, wastewater suspended substance clearance reaches 98.3%, and BOD clearance is 95.2%, and COD clearance is 96.8%.There is purification speed
Hurry up, effective, the advantage such as environment-protecting asepsis.
