Abstract

Based on the study of the design principle of ultrasonic cleaning device, the technology of ultrasonic water treatment and the application of ultrasonic on-line cleaning in membrane bioreactor test, several aspects to be considered in the design of ultrasonic on-line cleaning device in membrane bioreactor are summarized. Through 60-day continuous test, it is shown that the ultrasonic wave with ultrasonic frequency of 40KHz, ultrasonic power of 960W and cleaning time of 5min has a good cleaning effect on Polyvinylidene Fluoride membrane and ultrasonic cleaning has no adverse effect on the growth of microorganisms in Polyvinylidene Fluoride membrane and the quality of the effluent.
