摘要:
针对北京市雨水径流特性，选取3种典型的透水铺装系统即水泥透水砖、砂基透水砖和页岩透水砖，以面层破损实验和柱实验方式研究透水铺装系统对常规径流污染物（COD、NH4+-N、TN、TP）的去除效能和机制，探讨不同降雨重现期和透水铺装各床层的影响。结果表明，破损的面层材料经雨水浸泡后可能会出现污染物溶出现象，加剧径流污染。3种透水铺装系统出水中的径流污染物浓度变化趋势基本一致，随着运行时间的延长，大部分污染物的浓度先急剧降低随后出现不同程度的升高。水泥砖和砂基砖透水铺装系统对污染物的去除效能较为接近，均优于页岩砖透水铺装系统。3种透水铺装系统面层、基层下部以及底基层对COD和NH4+-N的去除效果较好；系统各床层对TN的去除效果均较差，甚至出现TN析出的现象，但对TP的去除效果均较好。当降雨重现期增加时，透水铺装系统对污染物的去除效果变差。
Abstract:
According to the characteristics of rainfall runoff in Beijing, three typical permeable pavement systems, namely cement permeable brick, sand-based permeable brick and shale permeable brick, were selected to investigate the conventional runoff pollutants (COD, NH4+-N, TN and TP) removal efficiency and removal mechanism of the permeable pavement system by surface damage experiment and column experiment, and the effects of different rainfall return periods and permeable pavement beds on runoff control were investigated. After the damaged surface material was soaked by rainwater, the pollutants might dissolve out and aggravated the runoff pollution. The variable trends of runoff pollutants concentration in the effluent from the three permeable pavement systems were basically the same. With the extension of operation time, most of the pollutants concentration firstly decreased sharply and then increased in different degrees. The pollutants removal efficiencies of the cement brick and sand?based brick permeable pavement systems were similar and superior to that of the shale brick permeable pavement system. The surface layer, the lower base layer and the bottom base layer of the three permeable pavement systems had a better COD and NH4+-N removal performance. The removal performance of TN in each bed of the system was poor, and even TN release phenomenon was observed. However, the removal performance of TP was good. When the rainfall return period increased, the pollutants removal performance of the permeable pavement system became worse.
