摘　　要：在污水处理中活性污泥法是最为普遍的处理工艺,而污泥膨胀是该工艺运行中最易发生危害最大的问题.本文研究了污泥膨胀的类型、诱发机理.指出了污泥膨胀的主要因素有污水水质、溶解氧、污泥负荷、冲击负荷以及运行方式和处理工艺等.并归纳了污泥膨胀的控制措施.Activated sludge process is used in many wastewater treatment plants, But it is often accompanied by sludge bulking which happens easily and harms the operation of activated sludge process seriously. This paper describes the type of sludge bulking and induced mechanism. Quality of wastewater, dissolved oxygen, sludge loading, shock loading, operation model and treatment processes are the main affecting factors for bulking sludge. It summed up the measures of controlling the sludge bulking.

关 键 词：污泥膨胀 诱发机理 控制措施
