Aeration.Conditioning tank water outlet enters A grades of biochemistry pools (anoxic pond) by elevator pump and O grades of biochemistry pools (aerobic tank) carry out biochemical treatment.
Organic component is higher in this engineering sewage, and BOD5/CODcr=0.5, biodegradability is fine, therefore big using bioremediation
Content of organics is most economical in amplitude reduction sewage.It is especially organic since ammonia nitrogen in sewage and content of organics are higher
Nitrogen, in biodegradable organic matter, organic nitrogen can be showed in the form of ammonia nitrogen, and ammonia nitrogen is also that an important contamination control refers to
Mark, therefore sewage treatment uses Anoxic/Aerobic A/O Biological Contact Oxidation Process, i.e. biochemistry pool need to be divided into A grades of ponds and O grades of two, ponds
Point.In A grades of ponds, since organic concentration is higher in sewage, microorganism is in anaerobic condition, and microorganism is facultative micro- life at this time
Object, organic nitrogen in sewage is converted ammonia nitrogen by they, while using organic carbon source as electron donor, by NO2--N, NO3--N
It is converted into N2, but also synthesizes new cellular material using part organic carbon source and ammonia nitrogen.So A grades of ponds not only have it is certain
Organic matter removal function mitigates the organic loading of subsequent O grades of biochemistry pool, in favor of nitrification progress, and by sewage
High-enriched organics, complete denitrification, the final eutrophication pollution for eliminating nitrogen.It is dirty by the biochemical action in A grades of ponds
Still with the presence of a certain amount of organic matter and higher nitrogen ammonia in water, to make the further oxygenolysis of organic matter, while making in carbonization
With tending in complete situation, nitrification can be gone on smoothly, and spy's O grade biochemistry pools of setting, the processing of O grades of biochemistry pools is by autotrophy
Type bacterium (nitrifier) is completed, they decompose the carbon dioxide in the inorganic carbon source generated or air as nutrition using organic matter
Mineralized nitrogen in sewage is NO2--N, NO3--N by source.It is mounted on filler in A grades and O grades of biochemistry pools, it is entire biochemical
What treatment process depended on the multiple-microorganism being attached on filler to complete.Dissolved oxygen control is on the left side 0.5mg/l in A grades of ponds
It is right；Dissolved oxygen control is in 2mg/l or more in O grades of biochemistry pools.O grades of ponds are discharged a part and are back to circulation in conditioning tank progress,
To reach denitrifying purpose, another part enters sedimentation basin and is precipitated, is separated by solid-liquid separation.Water outlet after separation is again through pumping
After further removing suspended impurity into mechanical filter, clear water qualified discharge or as greening water reuse.
The utility model has the beneficial effects that: the system is designed using standard modular, each function of height optimization
The performance of cell arrangement, by above-mentioned functional module it is highly integrated be a processing system, make its run the degree of automation significantly
It improves, while ensure that displacement mass is up to standard, equipment operation operation is convenient, and daily maintenance expense is low.

A kind of integrated A/O sewage disposal system provided in this embodiment, the sanitary sewage after collecting pass through one of grid,
Biggish suspended matter, floating material and ribbon in water removal are removed, gravity flow enters conditioning tank, and the purpose that conditioning tank is arranged is to adjust sewage
Water and water quality have boring aeration pipe to prevent suspended matter from precipitating in conditioning tank in conditioning tank base fabric, exposed using gap
Gas.Conditioning tank water outlet enters A grades of biochemistry pools (anoxic pond) by elevator pump and O grades of biochemistry pools (aerobic tank) carry out biochemical treatment.This
Organic component is higher in engineering sewage, and BOD5/CODcr=0.5, biodegradability is fine, therefore substantially using bioremediation
It is most economical that degree, which reduces content of organics in sewage,.Since ammonia nitrogen in sewage and content of organics are higher, especially organic nitrogen,
In biodegradable organic matter, organic nitrogen can be showed in the form of ammonia nitrogen, and ammonia nitrogen is also an important contamination control index,
Therefore sewage treatment uses Anoxic/Aerobic A/O Biological Contact Oxidation Process, i.e. biochemistry pool need to be divided into A grades of ponds and O grades of pond two parts.
In A grades of ponds, since organic concentration is higher in sewage, microorganism is in anaerobic condition, and microorganism is aerobic-anaerobic microbe at this time,
Organic nitrogen in sewage is converted ammonia nitrogen by they, while using organic carbon source as electron donor, NO2--N, NO3--N being converted
For N2, but also new cellular material is synthesized using part organic carbon source and ammonia nitrogen.So A grades of ponds not only have it is certain organic
Object removes function, mitigates the organic loading of subsequent O grades of biochemistry pool, in favor of nitrification progress, and by the height in sewage
Concentration organic completes denitrification, the final eutrophication pollution for eliminating nitrogen.By the biochemical action in A grades of ponds, in sewage
Still with the presence of a certain amount of organic matter and higher nitrogen ammonia, to make the further oxygenolysis of organic matter, while becoming in carbonization
In complete situation, nitrification can be gone on smoothly, spy's O grades of biochemistry pools of setting, and the processing of O grades of biochemistry pools is thin by autotrophic type
Bacterium (nitrifier) is completed, they decompose the carbon dioxide in the inorganic carbon source or air of generation as nutrient source using organic matter,
It is NO2--N, NO3--N by the mineralized nitrogen in sewage.Filler, entire biochemical treatment are mounted in A grades and O grades of biochemistry pools
What process depended on the multiple-microorganism being attached on filler to complete.Dissolved oxygen control is in 0.5mg/l or so in A grades of ponds；
Dissolved oxygen control is in 2mg/l or more in O grades of biochemistry pools.O grades of ponds are discharged a part and are back to circulation in conditioning tank progress, to reach
To denitrifying purpose, another part enters sedimentation basin and is precipitated, is separated by solid-liquid separation.Water outlet after separation enters through pump again
After mechanical filter further removes suspended impurity, clear water qualified discharge or as greening water reuse.
The beneficial effect of the present embodiment is: the system is designed using standard modular, each function list of height optimization
The performance of element apparatus, by above-mentioned functional module it is highly integrated be a processing system, make its run the degree of automation mention significantly
Height, while ensure that displacement mass is up to standard, equipment operation operation is convenient, and daily maintenance expense is low.
