摘　　要：污泥膨胀问题普遍并长期存在于全球污水处理厂中,是制约活性污泥工艺发展的难题之一。尽管国内外的研究者对污泥膨胀做了大量的研究,但仍然没有找到一个可行的全面的解决办法。本文总结了新近丝状菌的鉴定和表征方面的研究成果;分析了丝状菌的特性及其功能,结合丝状菌形成的诱因,提出了预防控制丝状污泥膨胀的工程化手段与最新工艺。同时,文章结合当前国内外最新研究结果,提出了需对丝状污泥进行控制与利用相结合的新方向。Bulking sludge problem is frequently occurred and notorious in sewage treatment plant. It is one of the problems which restricts the development of the activated sludge process. Although the extensive research have been done on bulking sludge, but there still can＇t find a feasible solution. This article presents a extensive-summarization for the relative definition of bulking sludge, elaborates the characteristics of filamentous bacteria and analyses the influencing factors of bulking sludge. The article also expounds several widely accepted theories on bulking sludge and their latest derivational controlling processes, hnplementing methods to prevent and control filamentous bulking have been put forward. This paper aims at providing useful guidance to investigate and control the filamentous bulking sludge.
