摘　　要：分析了影响截流倍数的影响因素，探讨了合理的截流倍数计算方法。通过某城市实例分析．发现合流制截流倍数应综合考虑合流水量．截流规模．排放污染物总量、水体排放要求及水体自净能力等，最终通过计算比较后确定。For a combined drainage system, factors influencing the interception ratio were analysed and its calculation method was studied. Based on the analysis of a city case, it was found that the interception ratio of a combined drainage system should be determined under the considerations and comparison of combined sewage flow, scope of the interception, total pollutant Ioadings, requirements for the effluent receiving water body and its assimilative capacity, and etc.

关 键 词：合流制 截流倍数 降雨强度 自净能力
