摘　　要：以中山市南头一水厂改造工程为例,将现有合建的"絮凝池+斜管沉淀池+无阀滤池"升级改造成"新网格絮凝池+上向与下向流斜板浮沉池+单阀滤池",创新地设计了斜板浮沉池的进水口,采用可移动闸板阀灵活切换进水口,形成"上向流斜板沉淀池"或"下向流斜板气浮池",以达到一池两用的目的,从而解决了由于现有工艺不能适应当前源水水质所导致的出水水质不达标的问题。Based on the upgrading of Nantou Waterworks in Zhongshan, the original combined process of flocculation tank, inclined-tube sedimentation tank and non-valve filter was u new combined process of grid flocculation tank, up/down-flow inclined-plate air flotation-sedimentation tank and single- tively designed. valve filter. The water inlet of inclined-plate air flotation-sedimentation tank was innova- The movable gate valve was used for switching the water inlet, which is the switch of up- flow inclined-plate sedimentation tank and down-flow inclined-plate air flotation tank, in order to switch two different processes （ air flotation and sedimentation） in the same tank. This upgrading solve the problem that the original treatment process could not adapt to the raw water ished water could not meet the standard.
