为了掌握长株潭地区路面径流污染特征,对该地区典型道路路面径流与沉积物进行了取样分析与测试。结果表明,路面径流中最主要的污染物为固体悬浮物,其次是化学需氧量（COD）;悬浮固体与其它污染物存在较好的相互依存关系,控制路面径流中的悬浮固体对控制其污染具有重要意义;路面沉积物的颗粒粒径主要集中在0.075-0.15 mm之间,其次为〈0.075 mm,粒径为1 mm以上的颗粒所占的比例很小,沉积物中COD含量主要集中在粒径小于0.15 mm的颗粒。

In order to master the characteristics of pavement runoff pollution in Changsha-zhuzhouxiangtan area,the pavement runoff and sediment of typical road in this area have been analyzed and tested. The results show that the suspended solids are the main pollutant in pavement runoff,followed by chemical oxygen demand. There is a interdependence between SS and other contaminants,controlling the suspended solids in the road runoff is of great significance to control the pollution. The particle size of road sediment is mainly concentrated between 0. 075 mm to 0. 15 mm,next for less than 0. 075 mm,the ...
