Embodiment:
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
See Fig. 1,2; The associated plant of the floating ship aeration of the utility model anaerobism, anoxic, aerobic and biological mould reactor drum comprises: anaerobic pond 1, anoxic pond 2, Aerobic Pond 3 and biological mould reactor cell 4, and described anaerobic pond 1, anoxic pond 2, Aerobic Pond 3 and biological mould reactor cell 4 are communicated with successively; After the sewage of rough handling flows into anaerobic pond 1, anoxic pond 2 and Aerobic Pond 3; Sewage flows into biological mould reactor cell 4 and carries out mud-water separation, and mud is according to a certain amount of backflow, and excess sludge is discharged.The mixed solution of Aerobic Pond 3 can be back in the anoxic pond 2, and the mixed solution in the anoxic pond 2 can be back in the anaerobic pond 1.Aerobic Pond 3 is provided with the floating ship aerator 31 that can float on WS and submerged, by aerator 31 input airs, promotes and mixed water body.Be provided with biological membrane assembly 41 in the described biological mould reactor cell 4; This biological membrane assembly 41 is installed in the biological mould reactor cell 4; Be positioned under the water surface; Sewage flows into biological mould reactor cell 4 and carries out mud-water separation, and sewage up to standard flows out from the water outlet of biological mould reactor cell 4 belows, and part mud is back to Aerobic Pond.
One dividing plate 32 vertically is set in Aerobic Pond 3, and the length of this dividing plate 32 is less than the length of Aerobic Pond 3.
Particularly; See the associated plant of the floating ship aeration of the anaerobism shown in Fig. 1-2, anoxic, aerobic and biological mould reactor drum, with can handle every day 5000 tons/about sewage quantity be example, advantage is separately given full play in each pond; Not only reduced floor space, treatment effect improves greatly.Sewage through rough handling flows into anaerobic pond 1, gets into anoxic pond 2 behind the polyP bacteria anaerobic phosphorus release in anaerobic pond 1 in the sewage, and the phosphorus content in this process sewage increases.In anoxic pond 2; Part sewage flows into from anaerobic pond 1; Part sewage refluxes from Aerobic Pond 3; Denitrifying bacteria utilizes the organism in the sewage to carry out nitrification as carbon source, and a large amount of nitrogenous organism of bringing in the sewage that will from Aerobic Pond 3, reflux is reduced to N2 and is released in the air, and the sewage of the anoxic pond of flowing through 2 continues to flow into Aerobic Pond 3.In Aerobic Pond 3, organism is continued to descend by the microbial biochemical degraded, and organonitrogen then by nitrated, is made NH by ammonification
3N concentration significantly descends, along with nitrifying process makes NO
3The concentration of-N increases, and phosphorus is along with the excess ingestion of polyP bacteria also descends, and nitrifying process produces contains NO
3The sewage backflow of-N carries out the denitrification denitrification in anoxic pond, the phosphorus content in this process in the sewage reduces.In Aerobic Pond 3, be provided with aerator 31, aerator 31 mixes inhaled air and sewage, and the generation bubble is tiny and quantity is various; Dissolved oxygen rate is high; The gas of high speed rotating, water, mud mixture (being active sludge) penetration power are strong, make oxygen transfer efficiency in water high, reach good mixing effect simultaneously; Can guarantee that active sludge mixes, keep active sludge to be suspended state.Sewage carries out mud-water separation through biological mould reactor cell 4 again, separates back sewage and flows out from biological mould reactor cell 4 belows.The associated plant of anaerobism, anoxic, the floating ship aeration of aerobic and biological mould reactor drum; Improved sludge concentration greatly; Reduced the discharging of excess sludge; Adopt this kind method denitrogenation dephosphorizing, its sludge concentration is traditional anaerobism, anoxic, aerobic combined reactor sludge concentration 3 to 4 times, the residence time of also having dwindled sewage greatly.
Certainly; The above is merely an embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
