摘　　要：东北地区低温低浊的地表水难以净化处理,而且地表水的水质在一年之中变化很大,采用常规的处理工艺很难达到新的水质标准。集气浮和沉淀于一体的浮沉池较好地解决了这一问题。介绍了浮沉池运行的原理、构造和工艺特点,总结了浮沉池的应用实例及运行效果,并指出了浮沉池在实际运行过程中存在跑矾花、排泥差等问题及其产生的原因,针对具体问题探讨了相应的解决方法。It is difficult to treat surface water of low temperature and low turbidity in north-east China. In addition, the significant variations of water quality in different seasons make it difficult to suit with new water standards. The problem is solved fairly by newly developed flotation-sedimentation tank with both function of flotation and sedimentation. The paper introduces the operation principle of flotation-sedimentation, the structure and the process features, summarizes the application and the operating efficiency. The paper also discusses some problems such as flockers, mud discharge and their causes, and finally suggests corresponding solutions to these specific problems.
