摘　　要：本文介绍了浮动填料活性污泥系统的开发背景与应用实践。试验表明应用浮动填料可大幅度提高曝气池中的活性污泥浓度并增加硝化菌的固着量，因而使该系统对ＣＯＤ、氨氮和总氮的去除能力均优于普通活性污泥系统。添加浮动填料可简易地改造现有的活性污泥法处理系统，以适应更严格的排放标准。可增加原系统的容积负荷，有良好的发展前景。A background of the suspended carrier activated sewage (SCAS)and its practice have been reviewed in this paper.Tests show that the equivalent sludge concentration and the quantity of nitrobacteria in the aerobic tank were increased when some suspended biomass supports were added in it.Therefore,the removal of COD ,NH + 4 N and TN from SCAS is improved in comparison with that from the conventional activated sludge process.This kind of combined biological process can upgrade the conventional one feasibly to meet the gradually strict demands of environmental protection regulation
