Description
Technical field
This utility model relates to a kind of sewage disposal device, more specifically refers to and can adopt a kind of A/O method domestic sewage treatment device based on biochemical treatment A/O method.
Background technology
In sewage treatment area, general bioanalysis can only remove BOD5、CODCr.To removing, ammonia nitrogen is inefficient or effect is unstable, does not reach Environmental Protection Agency's acceptance of work standard.Trace it to its cause be common sewage apparatus carry out sewage disposal only by general bioanalysis, and it is adaptable, and anti impulsion load is poor, and high volumetric loading is poor, can produce sludge bulking, and sludge volume is big, and denitrification effect is bad.
Utility model content
Main purpose of the present utility model is in that to provide a kind of A/O method domestic sewage treatment device, this utility model for general sewage disposal device to removing the inefficient defect of ammonia nitrogen, adopt anaerobic pond and the mode of Aerobic Pond series connection, through the activated sludge that Aerobic Pond flows out, it is back to front end anaerobic pond, denitrifying bacterium in returned sludge utilizes the Organic substance in raw sewage as carbon source, and a large amount of nitrate nitrogens (NO x-N) in backflow mixed liquor are reduced into N:, thus reaching the purpose of denitrogenation.This utility model, without additional denitrification equipment, also can guarantee that effluent quality can reach discharge standard.Without additional carbon and rear Aeration tank, build and operating cost is relatively low.
The technical solution adopted in the utility model is: a kind of A/O method domestic sewage treatment device, including the anaerobic pond accessed for sewage, the Aerobic Pond of conducting it is connected with this anaerobic pond, the second pond of conducting it is connected with this Aerobic Pond, stretch to the aerator in this Aerobic Pond and sludge treatment equipment, wherein, this sludge refluxing apparatus includes the first sludge return pipe, it is arranged on the first sludge reflux pump in this first sludge return pipe, second sludge return pipe and be arranged on the second sludge reflux pump in this second sludge return pipe, the two ends end to end of this first sludge return pipe respectively with this anaerobic pond, this Aerobic Pond docks, one end of this second sludge return pipe is docked with the bottom of this second pond, this second sludge return pipe docks with the bottom of this anaerobic pond.
This second pond is provided with guide shell and floss hole.
The beneficial effects of the utility model are: this utility model structurally includes the anaerobic pond accessed for sewage, the Aerobic Pond of conducting it is connected with this anaerobic pond, the second pond of conducting it is connected with this Aerobic Pond, stretch to the aerator in this Aerobic Pond and sludge treatment equipment, wherein, this sludge refluxing apparatus includes the first sludge return pipe, it is arranged on the first sludge reflux pump in this first sludge return pipe, second sludge return pipe and be arranged on the second sludge reflux pump in this second sludge return pipe, the two ends end to end of this first sludge return pipe respectively with this anaerobic pond, this Aerobic Pond docks, one end of this second sludge return pipe is docked with the bottom of this second pond, this second sludge return pipe docks with the bottom of this anaerobic pond.This utility model for general sewage disposal device to removing the inefficient defect of ammonia nitrogen, adopt anaerobic pond and the mode of Aerobic Pond series connection, through the activated sludge that Aerobic Pond flows out, it is back to front end anaerobic pond, denitrifying bacterium in returned sludge utilizes the Organic substance in raw sewage as carbon source, a large amount of nitrate nitrogens (NO x-N) in backflow mixed liquor are reduced into N:, thus reaching the purpose of denitrogenation.This utility model, without additional denitrification equipment, also can guarantee that effluent quality can reach discharge standard.Without additional carbon and rear Aeration tank, build and operating cost is relatively low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
nullIt is illustrated in figure 1 one of the present utility model and is preferably embodied as example，A kind of A/O method domestic sewage treatment device，Including the anaerobic pond 10 accessed for sewage、The Aerobic Pond 20 of conducting it is connected with this anaerobic pond 10、The second pond 30 of conducting it is connected with this Aerobic Pond 20、Stretch to the aerator 40 in this Aerobic Pond 20 and sludge treatment equipment 50，Wherein，This sludge refluxing apparatus 50 includes the first sludge return pipe 51、It is arranged on the first sludge reflux pump 52 in this first sludge return pipe 51、Second sludge return pipe 53 and be arranged on the second sludge reflux pump 54 in this second sludge return pipe 53，The two ends end to end of this first sludge return pipe 51 respectively with this anaerobic pond 10、This Aerobic Pond 20 docks，One end of this second sludge return pipe 53 is docked with the bottom of this second pond 30，This second sludge return pipe 53 docks with the bottom of this anaerobic pond 10.
Further, this second pond 30 is provided with guide shell 31 and floss hole 32.
This utility model to removing the inefficient defect of ammonia nitrogen for general sewage disposal device, adopts anaerobic pond and the mode of Aerobic Pond series connection, through the activated sludge that Aerobic Pond flows out, is back to front end anaerobic pond.Denitrifying bacterium in returned sludge utilizes the Organic substance in raw sewage as carbon source, and a large amount of nitrate nitrogens (NO x-N) in backflow mixed liquor are reduced into N:, thus reaching the purpose of denitrogenation.
Sewage is introduced anaerobic pond by this utility model, and the denitrifying bacterium in returned sludge utilizes the Organic substance in raw sewage as carbon source, and a large amount of nitrate nitrogens (NO x-N) in backflow mixed liquor are reduced into N:, thus reaching the purpose of denitrogenation；Sewage subsequently enters Aerobic Pond, and major part Organic substance obtains digestion degraded at this, arranges second pond after Aerobic Pond, partly precipitated sludge reflux is to anaerobic pond, to provide the microorganism of abundance, simultaneously by mixed-liquor return in Aerobic Pond to anaerobic pond, to ensure that anaerobic pond has enough nitrate.
For sanitary sewage or to ammonia nitrogen discharge have higher requirements time, this utility model, without additional denitrification equipment, also can guarantee that effluent quality can reach discharge standard；Denitrification is front, nitrated rear, if internal recycle, using the organic substrates in raw sewage as carbon source, it is not necessary to additional carbon and rear Aeration tank, builds and operating cost is relatively low.
Embodiment of the present utility model and accompanying drawing are intended merely to displaying design concept of the present utility model, and protection domain of the present utility model should not necessarily be limited to this embodiment.
Can be seen that purpose of design of the present utility model can effectively be implemented by narration above.The portion shows of embodiment the purpose of this utility model and implement function and structural themes, and include other equivalent replacement.
