摘　　要：活性污泥微生物群落研究对于阐明污水生物净化机制、优化工艺条件均具有重要的科学意义。近年来在高通量测序技术助力下,活性污泥微生物群落结构、丰度研究工作获得了众多很有意义的研究结果。文章综述了不同污水特征、工艺条件下活性污泥微生物群落结构、丰度的动态变化与污染物去除之间的相关性,讨论了各环境因素对微生物群落的影响机理,并提出通过改变微生物群落结构及丰度提高污水处理效率的应用策略,对进一步理解城市生活污水微生物降解机理和提高污水处理效率具有重要指导意义。The research on activated sludge microbial community has an important scientific significance for demonstrating biological purification mechanism and optimizing process. Recently, many studies on activated sludge microbial community structure and abundance attained much useful results with the aid of high throughput sequencing. In this paper, the relationship between activated sludge microbial community structure, abundance and process performance are reviewed underling different sewage characteristics, process operating parameters, and the mechanisms of environmental factors to change microbial community are discussed, and the suggestions for regulating microbial community to improve efficiency of sewage treatment are proposed, which is helpful to understand municipal sewage microorganism degradation mechanism and raise efficiency of sewage treatment.
