摘　　要：以大连市三道沟净水厂一期串联式双层平流沉淀池的工艺设计为例,介绍和分析了该池型的主要设计参数、进出口布置、上下层排泥布置、放空与采光等主要设计内容。该双层沉淀池运行后,进水量达到甚至超过了设计水量,出水水质稳定可靠,排泥设备运行良好,实现了节省占地优化设计的预期目的,能为同行业相关设计提供借鉴和参考。The process design of series double layer horizontal flow sedimentation tank in Sandao- gou Water Plant in Dalian City was introduced and analyzed, including the main design parameters, layout of inlet and outlet, arrangement of upper and lower sludge collectors, emptying, lighting and so on. During the operation of the sedimentation tank, the inflow quantity met or even exceeded the design one, the outflow quality was stable and reliable, and the sludge collectors operated well. The land saving aim was achieved to provide reference for similar designs.
