摘　　要：道路表面尤其是交通活动频繁的城市道路表面,能够通过汽车尾气排放、轮胎和路面磨损以及油脂的渗漏等累积大量的悬浮颗粒等污染物质,其中悬浮固体颗粒在城市路面降水径流污染物中占很高的比重。文章分析径流中悬浮颗粒的特性,详细分析了它与其它污染物的关系和它在水中的去除特性,以及径流冲刷对其形成的规律,为径流污染全过程控制提供参考,对径流污染的工程控制和非工程管理都能提供帮助。认为悬浮颗粒全过程削减对径流污染物的全过程控制起着极为重要的作用,是径流污染物全过程削减的主要途径之一。Through the automobile tail gas, the wear between the tire and road and the leakage of oil leave on the road surface especially some busy roads surface can accumulate a large amount of pollutant just like suspended substance（SS）. SS takes up very high rate among pollutant. The article analyses the characteristic of solid in road runoff, details the relationship between solid and other pollutant, its takeoff characteristic in water and the laws as the result of road runoff. It provides references on the control of runoff pollution. And it is helpful on the control of runoff pollution and non - engineering control. Reduction of solid makes a great effect on the whole control of runoff pollution and is the main way on it.
