Background technology
With the fast development of Chinese society economy, town and country drinking water source area is generally dirty in various degree by nitrogen, phosphorus etc.
Dye, lake storehouse water body eutrophication degree constantly aggravates.According to statistics, in state's control emphasis monitoring lake (reservoir) of 62, the whole nation, I~III
Lake (reservoir) ratio of class, IV~V class and bad V class water quality is respectively 61.3%, 30.6% and 8.1%；It there are about 60% lake
In eutrophic state, the large-scale fresh water lake eutrophication such as Taihu Lake, Chaohu, Dian Chi, Wuhan East Lake is extremely serious, algae water
China happens occasionally.
The Algae toxins of algae and its secretion cause drinking water source water quality deterioration, add waterworks intractability and
Processing cost；In addition, the algae organic matter produced in algae metabolic processes holdup time length, difficult biology in water body environment
Degraded, causes to generate DBPs in conventional water treatment process chlorination link, wherein nitrogenous disinfection byproducts are extremely bright
Aobvious, high degree threatens drinking water quality safety.Therefore, the removal of algae and ammonia nitrogen seems outstanding in raw water of micropolluted water
To be important.
Membrane biological reactor process (MBR techniques) is a kind of new waste water that membrane separation technique is organically combined with biotechnology
Biologic treating technique.MBR has efficient crown_interception because of its membrane module, and microorganism can be made to be trapped in bioreactor so as to real
Existing reactor hydraulic detention time (HRT's) and sludge age (SRT) is kept completely separate, and realizes to deep purification of waste water；Meanwhile, ammonia
Oxidation bacteria, nitrifier and polyP bacteria etc. can fully be bred in reactor, realize synchronous denitrification dephosphorizing.In recent years, MBR is in life
It is widely applied in sewage, industrial wastewater and micro pollution drinking water source processing.By denitrogenation and except algae unites two into one, exploitation
Simultaneous denitrification removes algae membrane bioreactor, can not only simplify raw water of micropolluted water handling process, reduce cost of investment and
Operating cost is reduced, can also realize that system high efficiency simultaneous denitrification removes algae stable operation.
Utility model content
The utility model in view of the shortcomings of the prior art there is provided a kind of compact conformation, small floor space, high treating effect,
The low simultaneous denitrification of operating cost removes algae membrane bioreactor.
To realize the utility model purpose, there is provided following technical scheme：A kind of simultaneous denitrification removes algae membrane bioreactor,
Including reactor body, it is characterised in that reactor body is separated into anaerobic zone arranged side by side, aerobic area and the region of aerobic zone three,
It is provided with aerobic zone below membrane module, membrane module and is provided with aerator, aerobic zone top is provided with discharge outlet, and bottom is provided with
Settling zone and sludge refluxing apparatus, settling zone bottom, which is provided with mud discharging mouth, anaerobic zone, is provided with agitating device, the nearly bottom in anaerobic zone
It is provided with end housing in water inlet and sludge reflux mouthful, aerobic area and is provided with hanging filler.
Preferably, reactor body is separated by two pieces of dividing plates, a dividing plate top and reactor body top interval, bottom
End is affixed with reactor body bottom, and No. two dividing plate tops and reactor body top are affixed, bottom and reactor body bottom
Interval, makes to be formed from bottom to top, then in the top-down flow path in aerobic area in anaerobic zone into water.
Preferably, settling zone is separately provided with back the sludge reflux mouthful of the mud pipeline connection nearly bottom in anaerobic zone, mud pipeline is returned
On be provided with sludge refluxing apparatus.
Preferably, membrane module is tubular membrane, curtain type membrane or plate film assembly.
Preferably, the volume ratio of anaerobic zone, aerobic area and aerobic zone three is 1:1:1.
Preferably, settling zone bottom is using rectangular pyramid, its base angle is 30 ~ 60 °.
The utility model beneficial effect：There is advantages below compared with prior art：1）Reactor is divided into from left to right to be detested
Oxygen area, aerobic area and the unit of aerobic zone three, compact conformation, floor space are small；2）Aerobic area hanging filler can apposition growth it is big
Biomembrane is measured, is conducive to strengthened denitrification to remove algae effect；3）Sewage treatment process is melted into a whole by reactor with membrane separation technique；4）
Aerobic zone membrane module is by algae and rejection to organics to settling zone, good separating effect.
