The utility model relates to an MBRJ type membrane biological all-in-one machine which comprises a grid, an anaerobic tank, an aerobic tank, an aeration pipe, a membrane assembly, a fan, an electric control system, a vibration device and a back flushing system. The anaerobic tank and the aerobic tank are communicated, the aeration pipe and the membrane assembly are arranged in the aerobic tank, the vibration device and the back flushing system are arranged around the membrane assembly, and an air outlet of the fan respectively extends to an anaerobic tank lower layer and an aerobic tank lower layer. The MBRJ type membrane biological all-in-one machine can achieve sludge-water separation, can efficiently treat sewage, the membrane assembly can solve the core problem of restraining a cover layerto be formed on a membrane, the back flushing system can enable pollutants with small combination force with the membrane to fall, the membrane flux increases by more than 20%, and the service life of the membrane assembly can be prolonged. Due to flushing of aeration steam bubbles, the permeation rate of the membrane assembly can be kept high for a long time.
Description
Technical field
The utility model relates to a kind of waste disposal plant, relates in particular to the biological all-in-one of a kind of MBRJ type film.
Background technology
MBR full name membrane bioreactor, with the emerging technology of application of membrane in sewage disposal, MBR can realize microbe matter simultaneously in the space of compactness degraded and ultra-filtration membrane separating pollution substance, and the degraded with separate between exist synergy, be a kind of efficient, practical sewage disposal technology.Do not contain suspended substance in its water outlet, COD is also very low, and only need add a small amount of sterilizing agent, avoided the secondary pollution of pipeline, draining can reuse or directly discharging, realized the resource utilization of sewage, MBR technique is more with the obvious advantage than traditional waste water tertiary treatment method, so this technique has broad application prospects.
But film is polluted in operational process easily, can cause membrane flux to descend, even causes film can't continue to use.Change the operation that membrane module recovers reactor and rely on, will certainly cause increasing the cost of reactor and the interruption of the cycle of operation, directly affect efficient and the work-ing life of membrane module, hindered its widespread use in practice.
The utility model content
The utility model for overcome the above problems provide a kind of simple in structure, outlet water organic substance content is low, the biological all-in-one of the MBRJ type film of good filtration effect, long service life.
The technical solution of the utility model is: comprise grid, anoxic pond, Aerobic Pond, aeration tube, membrane module, gas blower, electrical control system, vibrating device and back-purge system, described anoxic pond and Aerobic Pond are connected, be provided with aeration tube and membrane module in the Aerobic Pond, be surrounded with vibrating device and back-purge system around the described membrane module, described blower outlet leads to respectively anoxic pond lower floor and Aerobic Pond lower floor.
Described anoxic pond bottom is maze-type structure.
Described blower outlet also leads to vibrating device and back-purge system.
The utility model utilizes the selection perviousness of film, almost all microorganisms can be trapped in the biological all-in-one, this is so that film---and the biological concentration in the biological all-in-one is high, has greatly prolonged mud age, and the utmost point is removed ammonia nitrogen and larger molecular organics effectively, make the organic content of water outlet to very low, water outlet is as clear as crystal, and no suspended substance can directly carry out reuse as reclaimed water, thereby be specially adapted to biotope or water-deficient area use, also be widely used in Industrial Wastewater Treatment.
This device can be realized mud-water separation, efficient sewerage processing, the key problem of optimization of membrane module design is will be suppressed to form tectum on the film as far as possible, the utilization of back-purge system can make with the less pollutent of binding force of membrane and come off, membrane flux on average increases more than 20%, life-span that can membrane component and prolong.Washing away of aeration steam bubble is conducive to for a long time higher infiltration rate of maintenance of membrane module.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is anoxic pond among the figure, the 2nd, and Aerobic Pond, the 3rd, membrane module, the 4th, gas blower, the 5th, vibrating device, the 6th, back-purge system.
Embodiment
The biological all-in-one of MBRJ type film, comprise grid, anoxic pond 1, Aerobic Pond 2, aeration tube, membrane module 3, gas blower 4, electrical control system, vibrating device 5 and back-purge system 6, described anoxic pond 1 and Aerobic Pond 2 are connected, filler all is immersed in the sewage during described Aerobic Pond 2 operation, utilize gas blower 4 to the water body oxygenation, the microbial film overwhelming majority is attached on the consubstantiality filler, because adsorption, adhere to one deck thin water layer that remains in a standstill on the biofilm surface, airborne oxygen enters microbial film by detention layer, under aerobic conditions, microorganism adsorption in the continuous tunicle of organism in the sewage layer, oxygenolysis, organic concentration in the detention layer is significantly less than fluidised bed, under the mass transfer force effect, organism in the fluidised bed constantly shifts to adhesion layer, fluidised bed progressively is purified in overall flow, reach dispose of sewage in organic purpose, be provided with aeration tube and membrane module 3 in the Aerobic Pond 2, because the aperture that film is 0.3 micron can stop bacterium to pass through, so can all be retained in bacterium micelle and free bacteria in the pond, thereby realized mud-water separation, exempted follow-up second pond, various suspended particles, bacterium, algae, COD and organism all can effectively be removed, guarantee water suspension and approached zero good effluent quality, can direct reuse.Because the intimate hundred-percent bacterium buffer action of microfiltration membrane, biological concentration is reached more than 10,000 mg/L, not only improved the ability of Aerobic Pond anti-shock loading, and required Aerobic Pond volume is reduced to 1/8～1/5 of traditional aeration mode, pool volume dwindle investment cost and the working cost that greatly reduces biochemical system.Be surrounded with vibrating device 5 and back-purge system 6 around the described membrane module 3, when scale effect on microbial film or the filtering membrane moves, Vibration on Start-up device 5, back-purge system 6, snaking, make microbial film or filtering membrane recover normal function, vibrating device 5 is comprised of air compressor machine and dither, and vibration intensity and frequency should transfer to the caducous intensity of dirt and frequency and be advisable.Back-purge system is by inside with high pressure gas, water, be that strainer inner chamber and microbial film attachment are inner, press flushing to spray, its spray punching press by force should be in the withstand voltage scope of hollow-fibre membrane, described gas blower 4 air outlets lead to respectively anoxic pond 1 lower floor and Aerobic Pond 2 lower floors, described anoxic pond 1 bottom is maze-type structure, so that anaerobic digestion procedure, anaerobic digestion is more abundant, the labyrinth channel diameter can be decided according to design scale, and described gas blower 4 air outlets also lead to vibrating device 5 and back-purge system 6.
