海绵型生态处理技术解决公路径流污染问题

摘要：公路路面径流中所含的污染成分较多，污染强度较大，肆意排放会对公路周边的自然环境产生较大的影响。传统的处理手段难以达到较好的净化效果，而通过生态处理技术，可对公路路面的径流污染起到很好的治理效果。通过研究国内外对于公路路面径流污染生态处理技术的研究现状，本文提出以植草沟和人工湿地相结合的生态处理技术，可有效去除径流污染物，提高径流水质，并加以综合利用。

Abstract

Highway road runoff contains more pollution components, pollution intensity is greater, wanton emissions will have a greater impact on the natural environment around the highway. The traditional means of treatment is difficult to achieve better purification effect, and through the ecological treatment technology, can be on the road surface runoff pollution play a very good governance effect. Based on the research status of the research on the ecological treatment technology of runoff pollution at road and abroad at home and abroad, this paper puts forward the ecological treatment technology , which can effectively remove runoff pollutants, improve runoff water quality, and to be comprehensive utilization.
