摘　　要：通过总结文献发现,不同地区造成污泥膨胀的丝状菌类似,包括Ca.M.parvicella、Thiothrix、H.hydrossis、Ca.Amarolinea等,其中以Ca.M.parvicella为主。温度过低、pH过低、溶解氧浓度不足、污泥负荷过低、氮磷等营养物质含量不足等均可能导致丝状菌的大量繁殖并引发污泥膨胀。结合研究现状重点介绍了利用群体感应相关技术控制污泥膨胀的方法,并提出相关技术的发展方向,为活性污泥法稳定运行和科学管理提供理论依据。By summarizing the existing literature,the filamentous bacteria detected in the different countries and regions are similar,which mainly include Ca.M.parvicella,Thiothrix,H.hydrossis,Ca.Amarolinea.Many factors such as nutrients,temperature,pH,dissolved oxygen content,and sludge load could affect the growth of filamentous bacteria severely.Although the overgrowth of filamentous bacteria can be inhibited by adjusting the operating parameters or adding chemicals,such common methods have some limitations.Combined with the current status of research,new methods based on quorum sensing and quorum quenching are also introduced.
