路面清扫对地表径流污染控制研究

摘要:

路面清扫是路面径流污染控制的有效措施。以苏州市某建成区为研究区域,选取不同类型道路广场,开展机械清扫作业、机械清洗作业、人工清扫作业对路面污染物的去除效果,同时与LID等工程措施进行运维成本的经济性对比分析。结果表明,机械化清扫作业和清洗作业后,路面SS污染物浓度可降低40~50%。路面清扫作业运维成本低于源头LID设施,应选择适宜的LID设施与路面清扫等联动实施,提高污染物去除效果的同时降低运维成本。

Abstract:

Road sweeping is an effective measure to control runoff pollution. Taking a built-up area in Suzhou as the research area, different types of road squares were selected to carry out mechanical sweeping operation, mechanical sweeping and scour operation and manual sweeping operation on the removal effect of road pollutants. At the same time, the economy of operation and maintenance cost was compared with LID engineering measures. The results showed that the concentration of SS could be reduced by 40~50 after mechanical sweeping and scour operation. The operation and maintenance cost of road sweeping operation was lower than that of LID facilities at the source. It is necessary to select appropriate LID facilities and road sweeping to improve the pollutant removal effect and reduce the operation and maintenance cost.
