Description

A kind of sewage disposal system
Technical field
This utility model is related to a kind of processing system, and in particular, it is related to a kind of sewage disposal system.
Background technology
A traditional stage biological denitrification process(Traditional A2/O techniques [1] and its various change form-various improvement A2/ O techniques), its denitrification ability is relevant with reflux ratio. and theoretical limit superior denitrification ability is R/ (1+R),(R- reflux ratios, including interior time Stream and exteenal reflux).In engineering, the general maximum of R values accomplishes 3 ~ 4, therefore maximum limit denitrification ability 75 ~ 80%.Actually by various According to the A2/O system datas of domestic and international operation, the restriction of reaction condition, sees that the denitrogenation level of a stage biological denitrification process is very It is difficult stably to keep more than 65%.This engine request TN clearances are 74.2%, therefore cannot be expired using conventional first order section biological denitrificaion The requirement up to standard of this project treatment of foot.
Utility model content
In order to solve above-mentioned technical problem, the utility model discloses a kind of sewage disposal system, solves the above Problem.
For achieving the above object, this utility model provides a kind of sewage disposal system of following technical scheme, and its feature exists In:Including the anaerobic pond being sequentially communicated, the first anoxic pond, the first Aerobic Pond, the second anoxic pond, the second Aerobic Pond, the 3rd anoxia Pond, the 3rd Aerobic Pond and second pond, the anaerobic pond, the first anoxic pond, the second anoxic pond, the 3rd anoxic pond respectively with water inlet pipe Road is connected, and first anoxic pond, the first Aerobic Pond are connected by the first mixed-liquor return pipeline, first mixed liquor Reflux line is provided with the first mixed-liquor return pump, and second anoxic pond, the second Aerobic Pond pass through the second mixed-liquor return pipe Road is connected, and the second mixed-liquor return pipeline is provided with the second mixed-liquor return pump, the 3rd anoxic pond, the 3rd aerobic Pond is connected by the 3rd mixed-liquor return pipeline, and the 3rd mixed-liquor return pipeline is provided with the 3rd mixed-liquor return pump, The second pond is connected by sludge exteenal reflux pipeline with anaerobic pond, and the sludge exteenal reflux pipeline is provided with exteenal reflux axle stream Pump, is provided with aeration supervisor in first Aerobic Pond, the second Aerobic Pond, the 3rd Aerobic Pond.
Preferably, sludge pump is provided with second pond, the sludge pump is eight.
Preferably, aeration supervisor is provided with streamlined control valve, streamlined 24, the valve of control.
Preferably, agitator is provided with anaerobic pond, the agitator is 16.
Preferably, impeller is provided with the first anoxic pond, the second anoxic pond, the 3rd anoxic pond, the impeller is 70 Two.
The beneficial effects of the utility model are:This utility model is in order to remove being attached to of producing in two grades of hypoxia response ponds Nitrogen foam on sludge flco, arranges quick aerobic reaction tank behind two grades of hypoxia response ponds again, while to make two grades of hypoxia responses The ammonia discharged during sludge retention in pond is nitrified, it is also desirable to this aerobic reaction tank.Three-level lacks(It is good)Oxygen reaction tank Principle is lacked with two grades(It is good)Oxygen reaction tank principle is the same, further cuts down the pollutional load in sewage, it is ensured that TN standard water discharges.
Multipoint water feeding carries out reasonable distribution to water-inlet carbon source, ensures that the carbon source of biological denitrificaion needs first, is meeting denitrogenation On the premise of, biological phosphate-eliminating can also be guaranteed, it is ensured that whole system stable effluent quality qualified discharge.It is near according to this engineering The actual motion effect of six months, it is even lower that the technique can make water outlet TN reach below 10mg/L.
