Background technology
Membrane bioreactor (Membrane Bio-Reactor, MBR) is a kind of Novel sewage treatment process membrane separation technique being combined with biological principle and develop.It utilizes membrane separation device by the activated sludge in biochemical reaction tank and larger molecular organics matter effectively catching, substitutes second pond.Compared with traditional handicraft, the advantage such as it has good effect of separating solid from liquid, effluent quality is good, sludge yield is low, biomass is high in bioreactor, floor space is little, the range of application in sewage disposal and scale constantly expand.But the extensive utilization of membrane reactor receives the restriction of the problems such as film price, fouling membrane and high energy consumption.Wherein fouling membrane is the principal element of restriction MBR large-scale promotion, and therefore, seeking better approach, to solve MBR membrane pollution problem be also one of current study hotspot.
Membrane cleaning is the effective ways that controlling diaphragm pollutes, reduces TMP (or recovering membrane flux), divides on-line cleaning and off-line cleaning, divide physical cleaning and Chemical cleaning by method by form.Online physical cleaning mainly comprises sky aeration (or air douche) and hydraulic reverse rinses 2 kinds of forms, but use frequently and easily cause membrane module to destroy (Le-C lech et al., 2006). the online physical cleaning such as empty aeration, hydraulic reverse flushing can only the development of respite fouling membrane, and the auxiliary cleaning measure being suitable as in-site chemical cleaning uses.Chemical cleaning is that the cleaning solution using the chemical agent of certain density particular types to prepare cleans filter membrane, and chemical agent can be the preparation etc. of acid, alkali, oxidant, reducing agent, surfactant and mixed preparing thereof.But chemicals impacts large to microorganism in system, can cause damage, and be not suitable for drinking regular maintenance and cleaning to membrane material.
Summary of the invention
The object of this invention is to provide a kind of method of ultrasonic cleaning equipment and cleaning MBR milipore filter thereof, with the problem solved.
For solving the problems of the technologies described above, the invention provides a kind of method of ultrasonic cleaning equipment and cleaning MBR milipore filter thereof, comprising control module and cleaning module, cleaning module comprises reaction tank and at least one piece of ultrasonic wave vibration plate be arranged on the inwall of reaction tank; Control module comprises the computer, controller and the supersonic generator that connect successively, and supersonic generator is connected with at least one piece of ultrasonic wave vibration plate.
Further, reaction tank is cube tank.
Further, the quantity of ultrasonic wave vibration plate is two pieces.
Further, two pieces of ultrasonic wave vibration plates are separately positioned on the relative inwall of two of reaction tank.
Further, controller is PLC.
Utilize above-mentioned ultrasonic cleaning equipment to clean a method for MBR milipore filter, comprise the following steps:
