干旱地区公路径流污染防治措施

Prevention and control measures of road runoff pollution in arid areas

为了探索干旱地区公路径流污染对周边环境的影响及相应的工程治理措施,研究了国内外公路径流污染治理措施的相关文献,分析了径流污染的来源、污染物的主要成分、污染物的理化性质以及对周边环境的危害,结合宁夏干旱地区实际及工程经验,提出了植被措施、氧化塘、人工湿地以及组合措施等工程措施以及相应的污染处理机理及预期效果,为今后的干旱地区公路径流污染防治设计提供参考,并对当前研究的现状进行总结和展望,为今后的研究提供参考方向。

In order to explore the impact of highway runoff pollution on the surrounding environment in arid areas and the corresponding engineering treatment measures, the relevant literature on highway runoff pollution treatment measures at home and abroad were studied, the source of runoff pollution, the main components of pollutants, the physical and chemical properties of pollutants and the harm to the surrounding environment were analyzed, and vegetation measures, oxidation ponds were put forward. The engineering measures such as constructed wetland and combined measures, as well as the corresponding pollution treatment mechanism and expected effect, a reference for the future design of highway runoff pollution control in arid areas were provided. It also summarized and prospected the current research status, and provides a reference direction for future research.
