摘要
为研究适用于弱透水土质的改良型透水铺装对典型雨水径流污染物悬浮固体(SS)的去除效果,以嘉兴地区的淤泥质黏土为土基层制作试验装置,以人工模拟降雨的方法模拟并检测不同降雨重现期条件下改良型透水铺装装置削减径流污染物SS的效果,并以常规透水铺装和普通路面作为对比。结果表明:较小的降雨重现期更有利于透水铺装对SS的去除;弱透水土质条件下改良型透水铺装在对SS的去除过程中,不但去除率高于常规透水铺装,去除速率也得到了提高;在降雨重现期1a条件下,改良型透水铺装平均每分钟比常规透水铺装多去除29.82%的SS。
In order to study the removal effect of improved permeable pavement, which is suitable for weak permeable soil quality, on typical rainwater runoff pollutant suspended solids(SS), a test device with silty clay of Jiaxing City as soil base layer was made, and the effect of improved permeable pavement device on reducing SS of runoff pollutants under different rainfall recurrence periods was simulated and tested by a method of artificial simulation of rainfall, and a comparison with conventional permeable paving device and ordinary paving device was made. The results show that smaller rainfall recurrence period is more conducive to SS removal by permeable pavement, and in the process of SS removal by improved permeable pavement under weak permeable soil conditions, not only the removal rate is higher than that of conventional pervious pavement, but also the removal speed is also strengthened. Under the condition of 1 year rainfall recurrence period, on average, the improved permeable pavement removes 29.82% more SS pollutants per minute than the conventional permeable pavement.
