简要介绍了北京市第九水厂污泥处理工程及其工艺设计。工程运行表明处理后上清液出水可以均匀回流至配水井重复使用，而经板框压滤机脱水的泥饼含水率约为５０％～６０％。
The sludge treatment project and its process design for Beijing No. 9 Water Plant were briefly introduced. The engineering operation shows that the effluent of the supernatant after treatment can be uniformly returned to the water distribution well for repeated use, while the moisture content of the dewatered mud cake by the frame and frame filter press is approximately 50% to 60%.
