人工湿地在路面径流污水处理中的应用

对采用人工湿地进行高速公路路面径流处理的方法进行了探讨。首先分析了路面径流的主要污染成分,论证了人工湿地处理此类污水的适用性。然后,对人工湿地的处理原理进行了阐述。最后,结合广东渝湛高速公路(粤境段)的实际情况,对处理路面径流的人工湿地的设计方法进行了探讨,突出体现了其与普通城市污水处理的差异性。设计方法可以为国内路面径流的人工湿地处理设计提供参考借鉴。

Application of Artificial Wet Land to Pavement Run-off Pollution Treatment

The method for pavement run-off pollution treated by artificial wet land is discussed.Firstly,The main compositions of pavement run-off pollution are analyzed,and it can be proved that the artificial wet land is suitable for treating pavement run-off pollution.Secondly,the treatment theory of artificial wet land is illustrated.Last,combined with Yu-Zhan Expressway in Guangdong Province,the design technique of the artificial wet land for pavement run-off pollution treatment are presented.It is emphasized that this design technique is different from the technique of the artificial wet land for city water pollution treatment.This research can provide the referenced example for other artificial wet land to treat pavement run-off pollution in China.
