摘要
综述了污水处理微生物学近期的研究现状,介绍了一些仍不能培养的细菌被鉴定为对污泥膨胀、提高生物学除磷、亚硝酸盐氧化和脱氮负责,而许多原来认为的优势群体却对污水处理不是最重要的.这些知识可以为微生物多样性、种群动态、生态稳定和特定微生物种群活性等提供新的视野,可以应用于污水生物反应器的设计和处理参数的控制,为改进污水处理厂的处理策略等提供更多的理论基础和依据.
Molecular biotechnology as one of culture-independent methods has been increasingly used in the studies of wastewater microorganisms, and many uncultured populations have been revealed, which have changed many views of microbial ecology. This paper gives a succinct review of recent studies in wastewater microorganisms. Some novel, in many cases yet not cultured bacteria were identified to be responsible for filamentous bulking and foaming as well as phosphorus and nitrogen removal in wastewater treatment systems ; however, some predominate population recognized previouslY were proved unimportant. The data give some insights about microbial diversity, population dynamics, terns stability and specific microbial population activity, and they will be helpful to optimize plant design and parameter control. ecosysprocess
