[0002] Membrane bioreactor is a device that combines membrane technology with bioreactor. It is mainly used for wastewater treatment and water quality improvement. The structure of membrane bioreactor is generally composed of bioreactor, membrane pool and membrane assembly. The membrane assembly will gradually accumulate pollutants during use, including suspended solids, colloids, bacteria, etc., which will cause blockage of the membrane assembly and a decrease in flux after long-term operation. In order to maintain the normal operation of the membrane system, regular membrane cleaning is required to remove pollutants and restore the membrane flux.
