摘要
活性污泥是污水处理系统中脱氮、除磷以及有机污染物质转化的主体,其生物活性的高低从根本上决定了污水处理系统的处理能力。认识活性污泥系统中微生物菌群的结构和功能特性对于污水处理工艺性能的改良和优化有现实指导意义。综述了活性污泥系统中原核细胞型微生物和原生动物的群落结构,以及两者各自的功能特性,包括原核细胞型微生物对氮、磷和其他特定污染物的去除作用,原生动物的指示作用。
Activated sludge is the major part of the removal of ammonium,nitrogen,phosphorus and the mass transi-tion of organic pollutants in wastewater treatment systems. The scale of biological activity fundamentally determines the treatment capacity of wastewater treatment systems. Recognizing the structure and functional characteristics of microbial communities in the activated sludge system has practical and leading meaning for the improvement and optimization of wastewater treatment process. The flora structures of procaryotic cell microbe and protozoan in acti-vated sludge systems,as well as their functional characteristics are summarized,including the removal effect on ni-trogen,phosphorus and other specific pollutants of procaryotic cell microbe and the indicative function of protozoan.
