Description
Technical field
The utility model relates to a kind of biological carbon and phosphorous removal treatment unit that is used for municipal sewage treatment, belongs to technical field of sewage.
Background technology
For control body eutrophication trend increases the weight of, strict municipal sewage plant's nitrogen, phosphorus emission standard have all been formulated in countries in the world.Compare with the traditional biological denitrification dephosphorization technique, inversion by anaerobism, anaerobic environment, inversion A/A/0 (hypoxic/anaerobic/aerobic) technology has that the denitrogenation dephosphorizing ability is strong, flow process simple (only a cover mud refluxes), cost are low, the characteristics of economic operating cost, in recent years, this technology becomes the focus of municipal sewage treatment research and engineering application gradually.
But it is in service at the waste disposal plant of realizing inversion hypoxic/anaerobic/aerobic process, for realizing higher biological denitrification denitrification effect, need keep higher return sludge ratio, cause mud backflow well liquid level fall to increase, the lifting lift that this can increase sludge reflux pump has to a certain extent increased the energy consumption of mud return-flow system.
Summary of the invention
The utility model provides the little integral type of a kind of energy consumption to be inverted hypoxic/anaerobic/aerobic denitrogenation dephosphorizing waste disposal plant at the existing higher defective of returned sluge power consumption of being inverted hypoxic/anaerobic/aerobic urban sewage treating device existence in service.
The utility model adopts following technical solution:
Integral type is inverted hypoxic/anaerobic/aerobic sewage water denitrification dephosphorization apparatus, comprise biochemical reaction tank and settling tank, biochemical reaction tank comprises anoxic pond, anaerobic pond and the Aerobic Pond that is communicated with successively and separates, in anoxic pond and the anaerobic pond agitator is installed, be provided with aerating apparatus in the Aerobic Pond, suction dredger is installed in the settling tank, biochemical reaction tank and settling tank connect as one, separate by the water distribution partition wall between the Aerobic Pond of settling tank and biochemical reaction tank, be provided with the returned sluge channel between the anoxic pond of settling tank and biochemical reaction tank.
Lattice or branch gallery are divided gallery in anoxic pond and the anaerobic pond in the Aerobic Pond.
Agitator adopts underwater propeller.
Settling tank adopts vertical-flow form, also can adopt the flat flow form.
Aerating apparatus can adopt and hang the chain type aerator, also can adopt hard-wired aerator.
The biochemical reaction tank mixed solution enters settling tank and carries out solid-liquid separation after the water distribution of water distribution partition wall.Returned sluge is directly promoted by the suction dredger in the settling tank, in the returned sluge channel is back to the anoxic pond of reaction tank.
The utility model is one because biochemical reaction tank and settling tank are built jointly, water inlet front end and settling tank liquid level are basic identical, on the one hand, can significantly reduce the power consumption that mud refluxes, also significantly reduce simultaneously the elevation loss of entire sewage treatment plant, save the lifting expense of mud and sewage greatly, finally save the day-to-day operation cost; On the other hand, integrated design can reduce the civil engineering one-time investment cost of treatment facility greatly, and integral body is provided with and arranges compactly, saves and takes up an area of, and finally saves construction cost.
