Description of drawings
Fig. 1 is a principle schematic of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
See Fig. 1, small town sewage of the present invention is handled integrated apparatus and is comprised grid canal 1, equalizing tank 2, hydrolysis acidification pool 3, contact-oxidation pool 4, coagulation basin 5, tube settler 6, sterilization pool 7, the flow channel 8 that connects in order; 2 pairs of sewage of equalizing tank are spared the even amount of matter, avoid the water quality and quantity fluctuation that follow-up unit is impacted; Hydrolysis acidification pool 3 is converted into the small organic molecule of readily biodegradable with the larger molecular organics of difficult degradation in the sewage, is convenient to aerobic treatment, the part of degrading simultaneously organic pollutant; Contact-oxidation pool is established biologic packing material in 4 ponds, and apposition growth microbial film on the filler, and the oxygen that the mikrobe on the microbial film utilizes blower fan to provide can effectively be degraded the organic pollutant in the sewage; Inclined tube is installed in tube settler 6 ponds, can be effectively improved deposition efficiency; Sterilization pool 7 settling tank water outlets enter sterilization pool, but through the water qualified discharge after disinfecting; Flow channel 8 metering wastewater flows.
Said tube settler 6 is connected with sludge sump 9; Sludge sump 9 settlement on storage pond sludge discharged.
Said tube settler 6 is connected with hydrolysis acidification pool 3.
Said sludge sump 9 connects equalizing tank 2.
Waste water is removed the bulk foreign material through be discharged into grid canal 1 from stream mode, and water outlet waste water is through being discharged into equalizing tank 2 from stream mode behind grid, and the major function of equalizing tank 2 is the balanced water quality and the water yield.
Sewage through equalizing tank 2 regulating pondages and water quality is squeezed into hydrolysis acidification pool 3 (being anaerobic pond) by lift pump.Hydrolysis acidification pool 3 adopts the form of up flow anaerobic sludge blanket reactor.Sewage gets into hydrolysis acidification pool 3 by the bottom; In the process at upper reaches; Pass in the pond by the formed Sludge Bed of mikrobe, pollutent in the waste water (organism) is held back by Sludge Bed, through absorption, assimilation with decompose; Polymer, complicated organism are resolved into low molecule, simple organism, like organic acid etc.Simultaneously, major part is decomposed after endogenous digestion by tube settler 6 backflows excess sludge (mikrobe mainly is a bacterium) so far.
