Description
Technical field
The present invention relates to sewage treatment equipment, being specifically related to can be to membrane module during a kind of MBR technology processes waste water
Carry out the device of off-line cleaning.
Background technology
Membrane bioreactor (MBR) technology is that novel waste water membrane separation technique combined with biological treatment process processes
Technology.Membrane bioreactor is divided into immersion and split type two types, and having obtained wide variety of is submerged membrane
Biological reactor process.Nets impregnated is to be immersed in biological reaction pool by doughnut (or flat board) film, depends on
By the centrifugation of film by mud-water separation, being pumped out by clean water by producing water suction pump, active microorganism is the most complete
Proceed biodegradation in being retained in system, reach the purpose that muddy water is kept completely separate.With traditional waste water treatment process phase
Ratio, MBR technique due to its there is facility compact, floor space is little, pollutants removal rate is high, stable effluent quality and be prone to automatic
The advantages such as control, obtain increasingly extensive application in recent years in many industries such as electronics, chemical industry, medicine, food, environment.To the greatest extent
Pipe MBR film is hydrophilic film, but fouling membrane or inevitably in membrane separating process, film once contaminated will increase across
Membrane resistance, reduces membrane flux, affects serviceability and the life-span of film.Therefore, during daily operational management, the most right
Film carries out Chemical cleaning, to remove the pollutant on membrane removal surface and inside, recovers the water permeability of film.Chemical cleaning includes online clear
Wash (maintainability cleaning) and off-line cleans (restorative cleaning) two kinds of means.On-line cleaning can go to membrane removal surface and internal big portion
Divide pollutant, but the deep layer within part intractable pollutant and fenestra is polluted and can not effectively be removed, therefore also need every year
Membrane module is carried out off-line cleaning.It is to utilize sodium hypochlorite or citric acid medicinal liquid to carry out quiet to membrane module that conventional off-line cleans
Putting immersion a period of time, under the lowest water temperature condition, cleaning efficiency is low, and cleaning performance is the best.Dose is periodically added in service sink
Main to be estimated as, extensive dosing method causes the waste of cleaning agent, adds operating cost.The mud hardened in film silk surface
Granule can unnecessary consumption chemical agent, hinder contacting of medicinal liquid and film silk surface, reduction cleaning performance simultaneously.Therefore film is studied
The reason polluted, seeks to reduce fouling membrane, and the method for fast quick-recovery membrane specific flux is to promote the key point of membrane separation technique.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that one have simple to operate, cleaning efficiency is high, nothing
Pollute, the features such as film silk not damaged utilize ultrasound wave remove the off-line cleaning device of microbial fouling on MBR membrane module.
The present invention is achieved by the following technical programs: the ultrasound wave off-line cleaning device of a kind of MBR membrane module, mainly
Including cleaning sink, transducer, supersonic generator, MBR membrane module, filtering rack and atmospheric valve, described transducer is positioned at clearly
Wash water trench bottom is also connected with supersonic generator, and supersonic generator is positioned at cleaning sink side, cleaning sink opposite side side
Wall is equipped with atmospheric valve, and described drainage screen is placed in cleaning sink.
As preferably, described transducer is the acoustic matrix of several sound heads composition.
As preferably, the frequency of sound wave that described supersonic generator sends is 16-68kHz.
As preferably, described MBR membrane module is Nets impregnated.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described.
The ultrasound wave off-line cleaning device of a kind of MBR membrane module, mainly includes that cleaning sink 1, transducer 2, ultrasound wave are sent out
Raw device 3, MBR membrane module 4, filtration rack 5 and atmospheric valve 6, described transducer 2 is positioned at bottom cleaning sink 1 and sends out with ultrasound wave
Raw device 3 connects, and supersonic generator 3 is positioned at cleaning sink 1 side, and cleaning sink 1 opposite side sidewall is equipped with atmospheric valve 6, described
Filter rack 5 to be placed in cleaning sink 1, the acoustic matrix that described transducer 2 forms for several sound heads, described supersonic generator 3
The frequency of sound wave sent is 16-68kHz, and described MBR membrane module 4 is Nets impregnated.
During the work of this device, it would be desirable to cleaning sink 1 lifted up into by the MBR membrane module 4 of cleaning, it is placed on filtration rack 5, opens
Dynamic supersonic generator 3, alternating current power supply is converted into the power supply of ultrasonic frequency by supersonic generator 3, and its frequency range is general
For 16-68kHz, then by cable, power supply being flowed to transducer 2, transducer 2 is acoustic matrix by several sound head parallel combinations
Forming, electric energy is converted into frequency mechanical vibrational energy, is delivered in cleaning sink 1, makes to form the ultrasound wave shaken back and forth in water
Sound field.Ultrasound wave is the forward directed radiation of density interphase in water, makes liquid flowing produce ten hundreds of a diameter of 50-500 μm
Micro-bubble, these bubbles are formed at the negative pressuren zone of ultrasound wave longitudinal propagation, growth, and at zone of positive pressure rapid closing, are formed
" cavity " effect, in this process, bubble Guan Bi can form over the instantaneous pressure of 1000 atmospheric pressure, successive real estate
Raw instantaneous pressure constantly impacts the film silk surface of MBR membrane module 4 just as a succession of little " blast ", makes in film silk surface area gap
Microbial fouling rapid deterioration, thus obtain cleaning, recover membrane flux, when after the cleaning completing membrane module, rinse water
Groove 1 can be emptied by atmospheric valve 6.
The invention is not limited in that the ultrasound wave off-line of a kind of MBR membrane module involved by above-mentioned detailed description of the invention cleans
Device, those skilled in the art also can make multiple change accordingly, but any is equal to the present invention or similar change
Change and all should contain within the scope of the claims.
