Literature Review on Effect of Sludge Age on Microbial Community Structure in HMBR

Abstract

The composite membrane biological treatment process has the characteristics of high quality effluent and low membrane pollution, which is widely used in domestic and international water treatment industry. Based on the review of the basic research on membrane fouling mechanism and the comparison of the research results of MBR at home and abroad, from the perspective of microbial ecology, based on the new generation of environmental microbial analysis technology of high-throughput sequencing, this paper expounds the microbial ecological mechanism that sludge age changes the content of microbial metabolites and membrane fouling process by affecting the microbial community structure and physiological characteristics.
