摘　　要：透水混凝土铺装对雨水径流水质控制有显著效果,但随着使用时间的延长,铺装系统中的路面堵塞会越来越严重,水质处理能力也随之下降。试验表明,在一年重现期下,没有堵塞的透水混凝土路面对SS、COD、TN、TP、Cu的去除率分别是47%、40%、37%、43%、43%。当透水混凝土路面的堵塞率达到70%时,SS、COD、TN、TP、Cu的去除率分别下降到33%、27%、33%、34%、37%。随着透水混凝土路面的堵塞率的不断增大,其对径流中常见污染物的控制作用持续减弱。结果揭示了堵塞对径流水质控制的作用及变化,为透水混凝土铺装在海绵城市的建设过程中的应用及维护对策提供了技术支撑。Pervious concrete pavement have a significant effect on the of control of the rainfall rtmoff, but with the extension of the use time,the blockage will be more and more seriousand the water treatment capacity will also decline.Test shows,under one year return period, the removal rates were 47%, 40%, 37%, 43%, 43% for SS, COD, TN, TP, Cu by no blockage of pervious concrete pavement.When the blockage rate reached 70% ,the removal rates of SS,COD,TN,TP and Cu were decreased to 33% ,27% ,33% ,34% ,and 37%, respectively.With the increasing of blockage rate of pervious concrete pavement,the control effect on common pollutants in rtmoff continues to weaken.The results of this test revealed the effect and change of blockage on runoff water quality control, and provided technical support for the application and maintenance of pervious concrete pavement in the construction of sponge city.
