The pulse turbulence membrane bioreactor disclosed by the invention has the advantages that the purpose of washing a membrane is achieved in the water filtration process of the hollow fibrous membrane, sludge or particles are unlikely to be adsorbed on membrane fibers to cause blockage, the service life of the membrane fibers is prolonged, and the water filtration efficiency of the membrane bioreactor is improved.
Description
Technical field
The present invention relates to a kind of membrane bioreactor, specifically a kind of hollow-fiber membrane bioreactor with pulse, action of turbulent flow.
Background technology
Membrane bioreactor (Membrane Bio-Reactor) is called for short MBR, it is a kind of new type water treatment technology combined with biological processing unit by film separation unit, it utilizes membrane separation plant the active sludge in biochemical reaction tank and larger molecular organics to be retained, save second pond, thus reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.But membrane bioreactor is vulnerable to mud or particulate is adsorbed on film silk and results in blockage, and cause water outlet discontinuous, Drainage efficiency is low, and the work-ing life of film is short.This situation is very serious when shutdown.
Summary of the invention
The object of the invention is open a kind of mud or particulate is not easily adsorbed on film silk, film silk long service life, the membrane bioreactor that Drainage efficiency is high.
Technical scheme of the present invention is:
Pulse turbulence membrane bio-reactor, structure comprises: hollow-fiber membrane bioreactor, a gas blower, suction pump, a sludge pump and a surge generator.
Described hollow-fiber membrane bioreactor is polypropylene hollow fiber membrane or modified polysulfone hollow fiber film assembly, and profile is tubulose, on sale on the market, or can according to the ability of disposing of sewage and film manufacturer customized; Be provided with water distributor bottom hollow-fiber membrane bioreactor, described water distributor is the snakelike pipe of hollow porous.
Described gas blower magnetic valve is connected with the aeration tube arranged bottom hollow-fiber membrane bioreactor with pipeline.
One end of described suction pump is connected with hollow-fiber membrane bioreactor water outlet.
Described sludge pump is connected with the sludge outlet be provided with bottom hollow-fiber membrane bioreactor.
Described surge generator structure comprises water tank, bell jar, vapor pipe, siphon destructing tube, siphon manufacture vapor pipe and pulse water shoot; Be provided with bell jar inside water tank, one of pulse water shoot passes in bell jar, and other end passes water tank; Siphon destructing tube one end vapor pipe is connected; The vapor pipe the other end is connected with siphon manufacture pipe; Siphon manufactures the inside that the vapor pipe the other end stretches into pulse vapor pipe; The siphon pipe connecting manufactured between vapor pipe and vapor pipe is drawn a pipeline and is stretched into bell jar inside; Pulse water shoot extend into the water distributor in hollow-fiber membrane bioreactor, and is connected with water distributor.
Its principle of work is:
When sewage enters surge generator and liquid level exceedes the water-in of siphon manufacture pipe, waste water just manufactures pipe from siphon and flows down, such siphon manufactures pipe will become jet at vapor pipe internal shaping, air in bell jar will be siphoned away after forming jet, when waste water completely arrives pulse water shoot water-in, at this moment in bell jar, siphon is defined again, utilize siphon principle like this, just the water short period of time in surge generator water tank is discharged into the pulse water distributing device under film, at this moment the water in pond just produces pulse and springs up the turbulent flow that is shaped, supply water as long as have in such reactor, it is just constantly at manufacture pulse turbulent flow, during suction pump work, mud or particulate are just not easily adsorbed on film silk and result in blockage, keep the efficient water-flowing amount of film silk.Simultaneously when after ten minutes suction pump working hours, quit work two minutes, when suction pump quits work, magnetic valve also opens two minutes simultaneously, and at this moment pressurized air enters aeration tube and carries out aeration purge film.So no matter suction pump work still stops all constantly carrying out washing film, and mud or particulate are not easily adsorbed on film silk and result in blockage, and substantially prolongs the film silk life-span.This is a kind of brand-new membrane bioreactor, without the need to additionaling power, hollow-fibre membrane just can be made simultaneously to reach in drainage process and wash film object, energy-conserving and environment-protective, greatly improves membrane bioreactor Drainage efficiency.
