Preferably, membrane aerated bioreactor MABR is the product that membrane technology is combined with technology of biological membrane, by ventilative
Property film oxygen supply, in the case where keeping partial pressure to be lower than bubble point, the micropore on the intraluminal oxygen-permeable film wall of film enters lumen
Bubble-free aeration is realized in outside, and bubble-free aeration mass-transfer efficiency is high, and coefficient of oxygen utilization is close to 100%, is 5~7 times of tradition aeration.
The membrane material surface of MABR can form microbial film, and the oxygen from the intracavitary side of membrane tube is spread from the interior of biomembrane, come
Then internally spread from the surface of biomembrane from the substrate in sewage, due to the incorgruous mass transfer of oxygen and substrate cause it is micro- on membrane module
Biomembrane generates apparent layered structure, from inside to outside respectively aerobic layer and oxygen layer and anaerobic layer, the microbial film in MABR
Functionality layering can make the oxidation and synchronous nitration and denitrification reaction of microbial film complete independently dirt organic pollutants；
Membrane bioreactor (MBR) is the sewage treatment process for being combined into membrane separation technique and bioreactor, is with film
Separator replaces the secondary settling tank of traditional activated sludge process, can be efficiently separated by solid-liquid separation, and obtains water quality and is preferably discharged.
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 the area MBR 2
Reaction pool bottom 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, by rousing
Blower oxygen supply, sewage enter oxidation ditch by water inlet pipe 10, and water inlet pipe 10 is located above the pool wall in the area MABR 11, and sewage can
To enter the area MABR 11 by more water inlet pipes 10, wherein a water inlet pipe 10 is located at 4 side of outlet pipe in the area MBR 2, to consume
Dissolved oxygen in the water outlet of the area MBR 2, mitigates its influence to anaerobic state in the area MABR 11, to the denitrogenation dephosphorizing function of oxidation ditch
Strengthened, 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 provides for biological phosphate-eliminating
Oxygen environment, therefore sludge concentration needed for oxidation ditch is lower, the pool capacity in the area MBR 2 can also reduce, and reduce the aeration in the area MBR 2
Intensity 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, stirring
Device 12 plays the role of adjusting sewage fluidised form for making sludge keep suspended state, plays guiding role to the flowing of sewage,
Due to that oxygen can be made in micro- life 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 object film, therefore the sewage in the area MABR 11 is in anaerobic state, the activated sludge of sewage and suspension is in oxidation ditch
In to complete repeatedly to recycle, recycle stream in the area MABR 11 in anaerobic state and in the area MBR 2 in aerobic state need to be replaced
It is dynamic, Biological Phosphorus Removal Process can be carried out, (sludge pipe 14 is located under the pool wall in the area MABR 11 excess sludge by the discharge of sludge pipe 14
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；
Again, Dephosphorization reagent can be added into oxidation ditch by the chemicals dosing plant of outside setting, is improved with auxiliary total in sewage
The removal rate of phosphorus.
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,
Wherein, microbial film inside aerobic layer can be met to oxygen in 0.05MPa or so by being aerated pressure control in the film of membrane module 9
Demand, and sewage can be made in anaerobic state, the polyP bacteria in activated sludge carries out anaerobic phosphorus release, the area MBR 2 under anaerobic state
In gas-water ratio be 15:1, when the muddy water mixed solution that activated sludge and sewage are formed enters the area 2 MBR, polyP bacteria carries out aerobic super
Amount inhales phosphorus, and treated sewage is through suction pump 5, by 4 qualified discharge of outlet pipe, the sludge concentration in oxidation ditch maintains 3500~
4000 mg/L, the excess sludge rich in phosphorus is by being discharged oxidation ditch in sludge pipe 14, after concentration, stabilization, dehydration at outward transport
It sets；
Also, the total hrt of oxidation ditch is 8~10 h, and wherein 2 hydraulic detention time of the area MBR is 1~3 h；Sludge
Age is 3~5 days；Horizontal flow velocity is 0.25 m/s.
