Compared with water treatment equipment implemented by using a traditional activated sludge process, the land-occupied area of the integrated denitrification membrane bioreactor disclosed by the utility model can be saved by over 50%; the sludge retention time and the water retention time can be separated under the action of membrane filtration, therefore, the treatment effect is improved, the quality of discharged water is good, the discharged water can be directly used as reused water, and the problems of sludge-water separation and water quality deterioration in secondary sedimentation tanks caused by activated sludge bulking are solved.

Description

The integration denitrification membrane bioreactor
Technical field
The utility model relates to a kind of integration denitrification membrane bioreactor, belongs to technical field of sewage.
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, the integration denitrification membrane bioreactor is provided, and substitutes existing activated sludge process water treating equipment, and 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 integration denitrification membrane bioreactor comprises shell, and shell is tubbiness, is provided with inner core in the shell, and the inner core end face is lower than outer casing top surface, is provided with the gap between inner core bottom surface and the shell; Interior tube bottom and middle part are provided with aerating apparatus, the aerating apparatus of interior tube bottom and intake pump pipe connection, aerating apparatus and the pneumatic pump pipe connection at inner core middle part; Inner core top is provided with the biological denitrificaion membrane module; Biological denitrificaion membrane module top with go out water pump pipeline and be connected.
In the previous reaction device, the described pipeline that is connected with pneumatic pump with intake pump is provided with control valve.
Compared with prior art, the utility model is a kind of water treating equipment that oxygen-starved area, aerobic zone and biological denitrificaion film are combined and form, comparing floor space with the traditional activated sludge process water treating equipment can save over half, and can sludge retention time be separated with the current residence time by the membrane filtration effect, improve treatment effect, effluent quality is good, and water outlet can be directly as reuse water, and has solved second pond mud-water separation and water quality deterioration problem that activated sludge bulking causes.The utility model can be realized deviating from of nitrogen in a reactor, and the organism in effectively disposing of sewage, can effectively improve the drawback of traditional technology, the pollutant emission of realization minimum, minimum excess sludge production and good effluent quality, the entire treatment process operation is simple, effluent quality is safe and reliable.Be a kind of denitrogenation, the energy-conservation and integrated sewage disposal device of production capacity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in the accompanying drawing: the 1-shell, the 2-inner core, the 3-aerating apparatus, the 4-intake pump, the 5-pneumatic pump, 6-biological denitrificaion membrane module, 7-goes out water pump, the 8-control valve.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to any restriction of the present utility model.
The integration denitrification membrane bioreactor comprises shell 1, and shell 1 is tubbiness, is provided with inner core 2 in the shell 1, and inner core 2 end faces are lower than shell 1 end face; Be provided with the gap between inner core 2 bottom surfaces and the shell 1; Inner core 2 bottoms and middle part are provided with aerating apparatus 3, and described aerating apparatus 3 is cavity structure housings, and housing is provided with aperture.The aerating apparatus of interior tube bottom and intake pump 4 pipe connection, aerating apparatus and pneumatic pump 5 pipe connection at inner core middle part; Inner core 2 tops are provided with biological denitrificaion membrane module 6; Biological denitrificaion membrane module 6 tops with go out water pump 7 pipe connection.The described pipeline that is connected with pneumatic pump 5 with intake pump 4 is provided with control valve 8.
Working process of the present utility model and principle
As shown in Figure 1, sewage enters integration denitrification membrane bioreactor bottom by intake pump 4, in inner core 2, form the oxygen-starved area between two aerating apparatuss 3, sewage carries out organic degraded in the oxygen-starved area, the aerating apparatus of upwards crossing the inner core middle part then enters aerobic zone, the effect of and nitrococcus nitrated by aerobic autotrophic type, ammonia nitrogen in the sewage is oxidized to nitrite nitrogen or nitrate nitrogen, sewage passes through inner core 2 top overflows to the recirculating zone between inner core 2 and the shell 1 then, come back to the bottom of reactor, under anoxia condition, utilize denitrifying bacterium that nitrite and nitrate are converted into nitrogen and from waste water, overflow, realize that dirty effect falls in denitrogenation.Water outlet of the present utility model is extracted out by going out water pump 7 by biological denitrificaion membrane module 6, has realized zero sludge discharge truly, has reached high-quality water outlet effect.
