Background technology
Along with the sternness day by day of water resource environment situation, problem of water consumption is outstanding all the more, and water safety has become everybody the special problem of paying attention to.Therefore the purifying problem of municipal effluent also seems particularly important all the more.The more high explanation water pollution degree of the content of organonitrogen is more serious in the sewage, so scavenging process mainly is denitrification process.Purifying method commonly used at present mainly contains the natural biology method of purification and two kinds of the artificial methods of purification, because the natural biology method of purification cycle is long, generally need several days to tens days, floor space is very big, and the influence of surrounding environment health also is unfavorable for common popularization more greatly.At present the artificial method of purification mainly still adopts traditional activated sludge process water technology, and the used occupation area of equipment of traditional technology is big, and processing efficiency is low.And can cause the second pond mud-water separation after the activated sludge bulking in the equipment, and causing water quality deterioration, effluent characteristics is relatively poor.
Summary of the invention
The purpose of this utility model is, a kind of integrated oxygen-poor aerobic membrane bioreactor is provided, and substitutes existing activated sludge process water treating equipment, big to solve the existing installation floor space, processing efficiency is low, and the problem that effluent characteristics is undesirable overcomes the deficiencies in the prior art.
The technical solution of the utility model:
The integrated oxygen-poor aerobic membrane bioreactor comprises reaction tank, and the reaction tank bottom is provided with aerating apparatus, is provided with the biological denitrificaion membrane module in the reaction tank; Reaction tank one side is provided with anoxic pond and anaerobic pond successively; The reaction tank opposite side is provided with the mud-water separation pond; The pond open height in described anaerobic pond, anoxic pond, reaction tank and mud-water separation pond reduces successively; Anaerobic pond bottom and intake pump pipe connection, biological denitrificaion membrane module top with go out water pump pipeline and be connected.
In the previous reaction device, be provided with dividing plate in the described anoxic pond, dividing plate one side is preceding anoxic pond, and dividing plate one side is the back anoxic pond, is provided with the gap between dividing plate bottom and the anoxic pond bottom surface.
In the previous reaction device, top, described mud-water separation pond is connected with the anaerobic pond bottom pipe through reflux pump.
In the previous reaction device, bottom, described mud-water separation pond is connected with the reaction tank bottom pipe through recycle pump.
In the previous reaction device, described aerating apparatus and pneumatic pump pipe connection.
Compared with prior art, the utility model can not be removed nitrogen and the relatively poor shortcoming for the treatment of effect in the water body at the anaerobism technology.Adopt advanced membrane separation technique as the post-processing technology of anaerobism energy output technology, realize the short distance nitration process in the water body when membrane separation technique can be guaranteed the high quality water outlet, the part effluent recycling removes to realize denitrification to anoxic reacter then.
