摘　　要：介绍绍兴污水处理厂一期工程中污泥膨胀的处理对策,对发生污泥膨胀的水质特点、工况条件进行分析,认为污泥膨胀主要是由高浓度冲击负荷造成的。通过对泥龄、回流方式、污泥负荷、溶解氧等运行参数进行调节,使污泥膨胀得到有效控制。The occasion and countermeasures against the sludge bulking in the first stage engineering of Shaoxing Wastewater Treatment Plant are presented. For these the property of the inflow wastewater and the operating status in time when sludge bulking was occurred were discussed. It was believed the sludge bulking caused by high-concentrated shock-loading could be treated effectively by ways of adequate adjustment of sludge age, recycling ratio, sludge loading and DO level.
