中文摘要：为研究不同类型透水铺装对径流雨水的入渗和净化效果,利用建筑垃圾再生成为骨料,设计了3种不同结构的透水混凝土铺装系统(Permeable Concrete Pavement System,PCPS),分别为再生砖骨料透水混凝土铺装系统(PCPS1)、再生混凝土骨料透水混凝土铺装系统(PCPS2)和普通透水混凝土铺装系统(PCPS0),测试其在不同降雨重现期和污染物浓度下的雨水入渗能力以及对典型污染物SS、COD、TP、TN的净化能力。结果表明:PCPS的入渗和净化能力随降雨重现期和污染物浓度的增大而减弱;PCPS1对污染物SS、COD、TN的净化能力最好,最大净化率分别为98.95%、56.31%、34.11%,PCPS2的入渗能力以及对污染物TP的净化能力最好,最大净化率为76.50%。再生骨料透水混凝土铺装系统内部孔隙率较高且表面携带的附着物具有吸附功能,对径流雨水具有良好的入渗能力和净化效果,为今后建筑垃圾再利用提供了一种良好的途径。

外文摘要：In order to study the infiltration and purification effects of different types of permeable pavement on runoff and rainwater,this paper designs three permeable concrete pavement systems(PCPS)with different structures by using recycled aggregate of construction waste,namely recycled brick aggregate permeable concrete pavement system(PCPS1),recycled concrete aggregate permeable concrete pavement system(PCPS2) and ordinary permeable concrete pavement system(PCPS0). The rainwater infiltration capacity and the purification capacity of typical pollutant SS,COD,TP and TN are tested under different rainfall return periods and pollutant concentrations. The results show that the infiltration and purification capacity of PCPS decreases with the increase in rainfall return period and pollutant concentration;the PCPS1 has the best purification capacity of pollutant SS,COD and TN,the maximum purification rates are 98.95%,56.31% and 34.11% respectively,and the PCPS2 has the best infiltration capacity and purification capacity of pollutant TP,the maximum purification rate is 76.50%. Recycled aggregate PCPS has high internal porosity,and the attachments carried on the surface have adsorption function,which has good infiltration capacity and purification effect on runoff and rainwater,which provides a good way for the reuse of construction waste in the future.
