活性污泥法中细菌多样性综述_陈燕摘要:活性污泥法是污水处理最重要的生物处理工艺之一,活性污泥系统中的细菌群落是该技术的核心,准确地了解活性污泥中微生物的群落结构、关键功能、细菌的生理特性和作用机制是提高活性污泥处理工艺运行效果的重要依据。文章通过对相关文献的总结和分析,综述了活性污泥处理工艺中主要细菌群落(脱氮除磷细菌、丝状菌等)的多样性和生理生态学特征,为提高污水处理厂运行效能、增强功能稳定性提供一定的微生物学理论基础。关键词:污水处理;活性污泥;微生物生态;脱氮除磷细菌;丝状菌中图分类号:X703文献标志码:AReviewofBacterialDiversityoftheActivatedSludgeProcessChenYan,LiuGuohua,FanQiang,QiLu,WangHongchen(SchoolofEnvironmentandNaturalResources,RenminUniversityofChina,Beijing100872,China)Abstract:Activatedsludgeprocessisoneofthemostimportantbiologicaltechnologiesofwastewatertreatment.Bacterialcommunitiesoftheactivatedsludgesystemarethecoreofsuchtechnology.Accurateunderstandingofthecompositionanddynamicsofmicrobialcommunitiesintheactivatedsludge,thephysiologicalfeaturesandmechanismofkeyfunctionalbacteriaaretheimportantbasisforimprovementoftheoperationeffectoftheactivatedsludgeprocess.Inthispaper,basedonthesummaryandanalysisofrelevantliterature,diversity,physiologicalandecologicalcharacteristicsofthemainmicrobialcommunities(e.g.nutrientre
