Research Development of Treatment Measures on Road Runoff Pollution

When the road passes through the first-grade surface sources protection zones and secondary reserve for domestic and drinking water, Road runoff needs to be treated. Pollutant control index achieve environmental quality standards for surface water (GB 3838-2002) before being discharged. Road runoff treatment belongs to a new field. It is not very clear about the definition and not formed a mature system in domestic research. In the vast literature at home and abroad about pavement runoff, this article summarizing the engineering and non-engineering measures of pavement runoff, and discussing handling the problems existing in the research and future development trend, provides reference for the related research and engineering design.
