| Abstract: | Bulking sludge is a worldwide problem and is also a major factor to limit the development of activated sludge processes.Situation regarding the study of filamentous microorganisms is described and four general theories explaining the occurrence of bulking sludge are summarized in the article.Based on these general theories,a biological selector is discussed and the selector types are presented.The development situation and the future trend of bulking sludge control technique are also described,mainly based on the theories of microbiology and mathematic modeling.Finally,some further research topics to be urgently solved are introduced in the article. |
