城市雨水径流中颗粒物冲刷迁移规律研究进展

Flushing and Migration Laws of Particulate Matters in Urban Stormwater Runoff

国内外的研究表明,城市雨水径流的大部分污染物主要赋存于颗粒物中,雨水径流中的颗粒物也是导致城市排水系统阻塞、发生内涝灾害的原因之一。因此,澳大利亚等发达国家已经将颗粒物作为控制径流污染和场地规划的重要指标之一。系统介绍了国内外雨水径流中颗粒物的最新研究进展,以期为城市雨水控制利用、场地开发提供参考。

Many researchers found that most of pollutants in urban stormwater runoff were adsorbed in the particulate matters, which were one of the main reasons that caused waterlogging, because of the particulate sediment in the drain pipe or runoff inlet. So, the developed countries, such as Australia, adopt the particulate matters as the main parameter for runoff pollution control and site planning. Recent research progress of particulate matters in runoff was introduced to give a support for runoff pollution control and site development.
