摘　　要：进一步提高污染物降解效率成为工业废水处理发展的瓶颈,低强度超声波强化膜生物反应器(MBR)是有效缓解这一难题的可能途径。已有研究发现,改善微生物细胞膜通透性、提高酶活性和减缓膜污染是低强度超声波强化MBR效能的主要原因,但低强度超声波强化MBR增强微生物代谢调控的机制还需进一步研究,对低强度超声波增强MBR污染物强化去除—膜污染减缓—剩余污泥减量互馈关系的也需要加强研究,为难降解的工业废水的处理提供优化方法。Further improvement of the pollutants degradation efficiency has become a bottleneck of the development of industrial wastewater treatment,and low-intensity ultrasound enhanced membrane bioreactor(MBR)is a possible technique to effectively alleviate this problem.It has been found that improving the permeability of microbial cell membrane,enhancing enzyme activity and mitigating membrane fouling were the main reasons for the efficiency of low-intensity ultrasound enhanced MBR,but the mechanism of low-intensity ultrasound enhanced MBR to enhance microbial metabolism regulation needs further research,and the research on the reciprocal feeding relationships among low-intensity ultrasound enhanced MBR pollutant removal and membrane pollution alleviation and excess sludge reduction also needs to be strengthened.It can provide an optimized method for the treatment of refractory industrial wastewater.
