摘　　要：选取SCOD/TCOD作为评价稳定程度的标准,通过碱解液化的实验方法,对徐州市7个不同工艺的污水处理厂污泥稳定性进行了测试,以求污泥稳定性与污水处理工艺的关系,从而为污水处理工艺是否需要建设污泥消化池以及如何优化污水与污泥处理工艺系统提供参考性建议。SCOD/TCOD is adopted as evaluation criteria of sludge stabilization degree, and the experiment of sludge alkali decomposition is done to evaluate the sludge stabilization. With the criteria, the stabilization of sludge which is produced from seven wastewater treatment plants with different processes in the city of Xuzhou can be investigated through the experiment method. Thus, the relationship between sludge stabilization and wastewater treatment process can been ascertained. Consequently, some suggestions that whether it is necessary to build sludge digestion tank in wastewater treatment process and how optimize the wastewater and sludge treatment process system can be acquired.
