珲乌高速公路路面径流污水湿地净化模式

The Pattern of Wetland for Purifying Road Runoff Pollution of Hunchun-Ulanhaote Expressway

摘要: 以吉林省珲乌高速公路路面径流为研究对象，分析了径流的水质特性和污染物流出规律，并从有效去除主要污染物的角度，考虑在排水系统中采用人工湿地处理技术。利用人工湿地k-C*模型以及相关经验获得人工湿地的参数，其基本模式为：人工湿地位于公路两侧，分别收集、处理公路两边路面径流污水，以1 km长路段为一个雨水收集单位，单侧湿地面积191.6 m²，平均水深0.5 m。

Abstract: Taking the road surface runoff of Hunchun-Ulanhaote Expressway in Jilin Province as the research object, we analyzed the water quality characteristics and pollutant outflow law of the runoff, and considered the artificial wetland treatment technology in the drainage system from the perspective of effective removal of major pollutants. The parameters of the artificial wetland were obtained using the artificial wetland k-C* model and related experience. The basic model is: the artificial wetland is located on both sides of the highway, collecting and treating the road runoff sewage on both sides of the highway respectively, with a 1 km long road section as a rainwater collection unit, a single side wetland area of 191.6 m², and an average water depth of 0.5 m.
