摘要：

药剂法是一种有效的丝状菌污泥膨胀控制技术。采用药剂法可使污泥膨胀在短时间内得到控制,在污泥膨胀得到迅速控制及膨胀原因查明后,再通过采取调控微生物生长环境的措施,创造不利于丝状菌生长的环境,可避免膨胀再次发生。药剂法能迅速控制污泥膨胀对于污水厂的运行管理具有较大的实用价值。

Abstract:

Medical method is an effective technique tocontrol filamentous bacteriumsludge expansion. The filamen-tous sludge expansion can be controlled in a short time by the medical method, and it will save lots of time for finding out the expansion causes. After that, the livingconditions ofthe microorganismcan be adjusted tothe state that is not suitable for the growth amentous bacteria, sothat the recurrence ofsludge expansion can be avoided.The medical method that can control sludge expansion quicklyhas much practical value tothe operation ofwater treatment plants.

Key words: filamentous bacteria, sludge expansion, oxidant, weight gainingagent, flocculants
