In the utility model, anaerobic pond, anoxic pond, anoxic pond are conventional biological processing unit.
The treatment process of the utility model sanitary sewage:
Unit → water outlet the aftertreatment of septic tank effluent → grid → equalizing tank → anaerobism anaerobic pond → anoxic pond → Aerobic Pond → mud-water separation or discharge.
Illustrate:
1) the pretreated sanitary sewage at this place refers to through changing the sanitary sewage after the simple process such as excrement, oil removal, sand setting, water quality and quantity adjusting
2) water outlet aftertreatment refer to carry out disinfection, filtration, the processing of artificial swamp even depth reach completely can reuse treatment process measure.
Principle of work of the present utility model: sanitary sewage is after septic tank is processed, enter coarse rack, fine fack is removed large-sized floating matter and suspended substance and is tackled the foreign material that diameter is greater than 8mm, after water quality and the water yield that regulates sewage through equalizing tank, enter anaerobic pond with the lifting of equalizing tank lift pump, on the adjustable rotating speed liquid of sewage in anaerobic pond under pushing flow mixer effect, sewage possesses in the feature of complete at this, under the effect of anaerobion, do anaerobic acidification biochemical treatment, by the pollutent in water or degraded or small molecules, release fully phosphorus for polyP bacteria simultaneously a parking space and applicable envrionment conditions are provided, thereby improve the phosphor-removing effect of system, can improve the settling property of mud, prevent the growth of a strong bacterium, the stability of raising system.
The water outlet of anaerobic pond flows into anoxic pond, sewage mainly utilizes the charcoal source of sewage in anoxic pond, on adjustable rotating speed liquid in anoxic pond under pushing flow mixer effect, sewage possesses in the feature of complete at this, under the effect of anti-digestion bacterium, the nitric nitrogen in mixed-liquor return is carried out to anti-digestion and realizes biological denitrificaion.Complete the removal to pollutent nitrogen.The quantity of reflux of the mixed solution of Aerobic Pond is by the valve capable of regulating flow quantity of mixed-liquor return pump, thus the preferred removal efficiency of adjusting nitrogen.
The water outlet of anoxic pond flows into Aerobic Pond, and sewage mainly utilizes aerobic micro-the giving birth under the effect that digests bacterium of sewage to enter biological degradation to the organic pollutant in sewage in Aerobic Pond, completes the removal to organic pollutant.PolyP bacteria excess in Aerobic Pond in sewage absorbs phosphorus, and excess absorbs an active sludge part for phosphorus will discharge system as excess sludge, thereby realize biological phosphate-eliminating.
The water outlet of Aerobic Pond flows into mud-water separation unit, and sewage is through PVC inclined tube, and the active sludge that proportion is greater than water will struggle against to being lowered into collection mud cone, and supernatant liquor can be collected beyond discharger by effluent weir.Complete the removal to organic pollutant.The biological sludge overwhelming majority precipitating is back to anaerobic pond through sludge sump and sludge pump, and a part of excess sludge is by outside regularly outward transport discharge system.The promoted aerating apparatus of realizing sewage oxygenation adopts oxygen-transfer efficiency high type micro-pore aerator, adopts elevatedly, gets rid of rapidly after facilitating fault, easy to maintenance.
This device is after field adjustable operation is qualified, and 8. PLC housing can be realized unmanned management operation, fault alarm, and from realizing the effect of the intelligent automatic operation of PLC, daily management mission amount is extremely low.
Full technique realizes a complete setization, on-the-spot without cumbersome scene soil building operation; Full-buried type, does not affect view around substantially.
