摘要
介绍了桐乡市城市污水处理厂丝状菌污泥膨胀的处理对策,对发生污泥膨胀时的水质特点、工况条件进行分析,认为此次丝状菌污泥膨胀主要是由于低污泥负荷率、低溶解氧引起的。通过调整泥龄、污泥负荷、DO等运行参数,投加NaC lO溶液杀灭丝状菌等措施成功控制了此次污泥膨胀,可供同行参考。
The treatment countermeasures against the filamentous sludge bulking in Tongxiang Wastewater Treatment Plant are introduced. The wastewater quality characteristics and operation conditions during sludge bulking are analyzed. It is believed that the filamentous sludge bulking is caused by low sludge loading rate and low DO. It is effectively controlled by adjusting sludge age, mainly sludge loading and DO level, adding NaCIO to kill filamentous bacteria and so on, which provides reference for the designers.
