渗透铺装在部分发达酗家已得到广泛应用。作为城市雨洪调控的技术之一,渗透铺装不仅可以削减雨水径流量,减缓径流速度,还可以有效地控制部分城市非点源污染,改善径流水质。根据国内外近年的研究情况,从渗透铺装对城市雨水径流水质的净化方面介绍了渗透铺装在控制城市非点源污染中的应用研究情况。研究结果表明:渗透铺装对雨水径流中的总悬浮固体、磷、重金属有较好的去除效果,而对氮的去除效果不稳定。最后,对渗透铺装的研究和应用方向进行了展望。
Permeable pavement is widely used in some developed countries. As an urban stormwater management technique, permeable pavement can not only reduce stormwater runoff volume and slow the speed of runoff, but also control some urban non-point source pollution effectively and improve water quality of the runoff. Based on studies in recent years, highlight was given on permeable pavement in controlling urban non-point source pollution from improvement water quality of the runoff. Literature review demonstrated that permeable pavement is effective in removing TSS, phosphorus and heavy metals form stormwater runoff, while its nitrogen removal effectiveness is not stable. Finally, promising research directions of permeable pavement for development and application were predicted.
