摘　　要：作为沉淀与气浮有机结合的新型净水构筑物浮沉池,对于处理不同浊度的原水有很好的适应性。本文通过分析比较目前在东北地区已投产使用的多座浮沉池的运行实践,认为斜板浮沉池在生产实际中具有良好的可操作性。在原水浊度大于50度时采用斜板沉淀方式运行,沉降速度为0.25～0.3mm/s,表面负荷为9.0～11.5m^3/(m^2·h);浊度小于50度按气浮工艺运行,表面负荷采用9.0～11.5m^3/(m^2·h)。The lateral flow flotation-sedimentation tank with inclined planes,a hybrid of flotation and sedimentation tanks,is very adaptable to the treatment of raw water with variable turbidity,and some of them have been put into performance in northeast China.Through analysis and comparisons,the authors point out that this kind of new structure is pretty easy to operate.The function of the flotation-sedimentation tank varies according to the turbidity of the raw water:when the turbidity is above 50 degrees,it serves as a sedimentation tank with a settling velocity of 0.25～0.30mm/s and a surface loading of 9.0～11.5m^3/(m^2·h);when the turbidity is below 50 degrees,it acts as a flotation tank,while the surface loading is 9.0～ 11.5m^3/(m^2·h).
