摘　　要：雨水径流有明显的初期冲刷作用,初期雨水弃流至市政污水管道可有效减少雨水受纳水体的污染,同时降低雨水收集处理与利用的成本。建筑小区初期雨水弃流装置可分为容积式、半容积式、切换式、流量式、雨量式等多种型式。从构造、原理、特点等方面对现有的初期雨水弃流装置进行了分析与评价,以期为建筑小区初期雨水弃流装置的选用提供帮助,并对今后初期弃流装置设计提供思路。The rainwater runoff has obvious effect of flushing pollutants at the initial stage, mus discharging part of the initial flow of rainwater into municipal sewer would reduce river pollution and lower the cost of rainwater catchment system. Several practical devices for the initial rainwater split-flow in a residential building area were introduced, including volume type, semi-volume type, switch type, flow type and rainfall type. The existing devices for the initial rainwater split-flow were analysed and evaluated for their structure, principle and characteristics. The purpose is to offer help for the selection of devices for the initial rainwater split-flow in a residential building area and to provide ideas to improve the design of the devices.
