摘要
该文在确定路面径流污染物指标的基础上,通过人工配置道路径流水样,利用自制的室内试验设备,对所选择的6种透水性铺装过滤层材料的净化性能进行了测试和评价,根据过滤层材料的去污效能,推荐出适用不同污染状况公路的过滤层材料组合结构型式。研究表明透水性铺装加铺"过滤层"材料可以有效降低路面径流污染浓度,防止地下水被污染效果较为明显。
Purification performance of six selected permeable pavement filter materials was tested and evaluated through utilizing self-made indoor laboratory equipments and artificial pavement runoff water samples, based on the determined pavement runoff pollutant index. According to pollutants removal performance of different filter materials, this paper proposed filter materials composite structure models which are applicable to pavements with different pollution status. Studies have shown that paving filter layer materials in permeable pavement can efficiently reduce pollution concentration of pavement runoff, and has significant effect for polluting groundwater.
