摘　　要：在确定某城市合流制排水系统的截流倍数时,在截流总量、污染物排放总量和水体自净能力之间建立了动态平衡,采用旱季污水总量暴雨强度拟合法确定了合理的截流倍数,达到了节省工程投资和治理污染的目的。The dynamic balance was established among interception amount, pollutants discharge amount and self-purification capacity of water body, when determining interception ratio of combined drainage system in a city. The reasonable interception ratio was determined using fitting method of wastewater amount and storm intensity in dry season, thus reaching the goal of saving project investment and pollution control.

关 键 词：合流制 截流倍数 降雨强度 自净能力
