Abstract

The invention discloses an ultrasonic cleaning apparatus and a method of cleaning an MBR (Membrane Bio-Reactor) ultrafiltration membrane by using the same. The ultrasonic cleaning apparatus comprises a control module and a cleaning module; the cleaning module comprises a reaction pool and at least one ultrasonic vibration plate on the inner wall of the reaction pool; the control module comprises a computer, a controller and an ultrasonic wave generator which are in successive connection; and the ultrasonic wave generator is connected with at least one ultrasonic vibration plate. By utilizing the mechanical vibration and microturbulence phenomenon generated by ultrasonic wave in water, pollution substances are facilitated to be disengaged from the membrane surface; and the ultrasonic cleaning effect is intermittently applied to an anaerobic MBR on line, the pollution development speed of the ultrafilter membrane of the anaerobic MBR is slow. The cleaning method is simple to operate, low in power consumption, and free of mechanical loss on the membrane, and helps to prolong the service life of the membrane.

Description

technical field [0001] The invention relates to an ultrasonic cleaning device and a method for cleaning an MBR ultrafiltration membrane. Background technique [0002] Membrane Bio-Reactor (MBR) is a new sewage treatment process developed by combining membrane separation technology with biological principles. It uses a membrane separation device to effectively retain the activated sludge and macromolecular organic substances in the biochemical reaction tank, replacing the secondary settling tank. Compared with the traditional process, it has the advantages of good solid-liquid separation effect, good effluent quality, low sludge production, high biomass in the bioreactor, and small footprint. Its application range and scale in sewage treatment continue to expand. However, the widespread use of membrane reactors is limited by membrane prices, membrane fouling, and high energy consumption. Among them, membrane fouling is the main factor limiting the large-scale promotion ...
