Nitration denitrification reaction；
Membrane bioreactor (MBR) is the sewage treatment process for being combined into membrane separation technique and bioreactor, is
The secondary settling tank for replacing traditional activated sludge process with membrane separation device, can be efficiently separated by solid-liquid separation, and it is preferable to obtain water quality
Water outlet.
Specifically, oxidation ditch is in the continuous cycle type reaction tank of closing irrigation canals and ditches shape, due to special construction, oxidation ditch is same
When have that be thoroughly mixed can be in the guiding role of blender 12 after sewage enters oxidation ditch with two kinds of characteristics of fluid state of pulling flow type
Lower carry out one-way flow, but because mixed liquor will be completed repeatedly to recycle in oxidation ditch, and simultaneously because flow velocity is very fast, sewage is very
It can be oxidized a large amount of mixed liquor dilution in ditch gallery fastly, therefore again it is considered that fluidised form and process dynamics in oxidation ditch are special
Sign is to be thoroughly mixed formula, and the unique characteristics of fluid state of oxidation ditch is just utilized in the present apparatus, and the area MABR 11 and the area MBR 2 are placed in
In the same reaction tank, the area MBR 2 and the area MABR 11 are separated by partition wall body 7 and wall frame 13, make activated sludge alternately in the area MABR
It is circulated in the area 11 and MBR 2, improves the biological phosphor-removing effect of technique, and reduce operation difficulty；
Further, the area MBR 21 is made of separating film module 3, drainpipe 6, suction pump 5 and outlet pipe 4, is being located at MBR
The reaction pool bottom in area 2 is uniformly equipped with micro porous aeration head or aeration tube, and the area MBR 2 and aeration membrane module 9 are all made of air
Source is supplied oxygen by air blower, and sewage enters oxidation ditch by water inlet pipe 10, and water inlet pipe 10 is located above the pool wall in the area MABR 11, and
And sewage can enter the area MABR 11 by more water inlet pipes 10, wherein a water inlet pipe 10 is located at the outlet pipe 4 one in the area MBR 2
Side mitigates its influence to anaerobic state in the area MABR 11, the denitrogenation to oxidation ditch to consume the dissolved oxygen in the water outlet of the area MBR 2
Phosphorus removal functional is strengthened, and the water distribution quantity of each water inlet pipe 10 can distribute by a certain percentage according to water quality, and the area MBR 2 removes for biology
Phosphorus provides aerobic environment, therefore sludge concentration needed for oxidation ditch is lower, and the pool capacity in the area MBR 2 can also reduce, and reduce MBR
The aeration intensity in area 2 simultaneously thereby reduces energy consumption；
Further, the motor 8 for thering is aeration membrane module 9, blender 12 and control blender 12 to rotate in the area MABR 11,
Blender 12 plays the role of adjusting sewage fluidised form for making sludge keep suspended state, plays guiding to the flowing of sewage
Effect, due to that oxygen can be made on aeration 9 surface of membrane module by pressure in control film using aeration membrane module 9 in the area MABR 11
It is totally consumed in microbial film, therefore the sewage in the area MABR 11 is in anaerobic state, the activated sludge of sewage and suspension is in oxygen
Changing will complete repeatedly to recycle in ditch, need to replace and recycle in the area MBR 2 in the area MABR 11 in anaerobic state and in aerobic state
Flowing can carry out Biological Phosphorus Removal Process, and by the discharge of sludge pipe 14, (sludge pipe 14 is located under the pool wall in the area MABR 11 excess sludge
Side, the side diagonal positioned at water inlet pipe 10 can also serve as evacuated tube use, achieve the purpose that finally to remove total phosphorus, the biological phosphate-eliminating
Process is not necessarily to gathering denitrifying polyP bacteria and aerobic polyP bacteria, therefore operation is more simple, and phosphor-removing effect is more preferable, in sewage
Organic pollutant, ammonia nitrogen, total nitrogen etc. can be removed in the area MABR 11；
In conclusion sanitary sewage enters the area MABR 11 in oxidation ditch after pretreatment, through water inlet pipe 10, and stirring
It under the guiding role for mixing device 12, is sufficiently mixed with the activated sludge in oxidation ditch, the film surface of aeration membrane module 9 is attached with micro- life
Object film, some organic pollutants and ammonia nitrogen in sewage diffuse into aerobic layer inside microbial film, are decomposed and are converted into dioxy
Change carbon and nitrate, nitrate reversely diffuses to the organic pollutant outside microbial film and in oxygen layer and anaerobic layer, with sewage
Denitrification is carried out, N2 is formed and is escaped from water.
