摘　　要：搭建3种不同土壤介质层的生物滞留设施,研究预处理设施的过滤效果对生物滞留设施污染负荷的影响,并针对预处理设施常用的过滤介质开展单次及累积污染物去除效果的研究。研究表明,预处理设施能够显著提升下游生物滞留设施的极限污染负荷和排空速率。预处理设施SS去除率从0%提高到40%时,生物滞留设施的极限污染负荷提升80%左右;预处理设施SS去除率从40%提高到60%时,生物滞留设施的极限污染负荷提升幅度开始减弱。从综合效益角度考量,建议预处理设施SS去除率为40%左右。The single and cumulative pollutant removal effects of common filtration media in pretreatment were studied,and biological retention facilities of three different soil media layers were built to explore the effects of filtration effects of pretreatment facilities on pollution loads of biological retention facilities.The results show that the pretreatment facility can significantly increase the limit pollution load and emptying rate of the downstream bioretention facility.When the SS removal rate of pretreatment facilities is increased from 0%to 40%,the limit pollution load of biological retention facilities is increased by about 80%.When the SS removal rate of pretreatment facility is increased from 40%to 60%,the increase of the limit pollution load of the biological retention facility begins to weaken.From the perspective of comprehensive benefit,it is suggested that the SS removal rate of pretreatment facilities should be about 4o%.
