摘要
为更有效地改善径流污染问题,以苏州市某校园为例,利用StormDesk构建研究区的水文水质模型,模拟分析了不同结构形式、不同土质类型的透水铺装对径流污染物的去除效果.研究表明,全透水型铺装"净"效果最好,但其效果随重现期的增大逐渐下降,下降幅度呈递增趋势;在较小的重现期下,不同土质类型的透水铺装"净"效果无明显的差距,而随重现期逐渐增大,土壤层为粘土的透水铺装"净"效果明显优于壤土和砂土;对改善径流污染需求较高的路面改造建议优先选择全透水型铺装+粘土.研究结果可为相似地区进行LID设施改造提供参考意见.
Abstract
In order to improve the problem of runoff pollution more effectively,taking a campus in Suzhou City as an example,StormDesk was used to construct a hydrological and water quality model of the study area for simulating the effect of permeable pavement with different structural forms and soil types on the removal of runoff pollutants.The study shows that the"net"effect of fully permeable pavement is the best,but its effect decreases gradually with the increase of the return period,and the decrease shows an increasing trend;At a small return period,there is no obvious difference in the"net"effect of different soil types of permeable pavement.The"net"effect of different soil types of permeable pave-ment does not increase with the increase of the return period.The"net"effect of permeable pavement with clay soil layer is significantly better than that of loam and sand soil as the recurrence period gradually increases;For pavement renova-tion with high demand of runoff pollution improvement,it is recommended to prefer fully permeable pavement+clay soil.The results of the study can provide reference for the renovation of LID facilities in similar areas.
