摘　　要：以新型城市雨水蓄水材料——蓄水陶土作为吸附介质,研究其对武汉城市主干道雨水面源污染物的吸附、截留及净化雨水的效果。结果表明:蓄水陶土对SS的去除率>50%,对COD的最高去除率为53.8%,对TP的平均去除率为43.2%,对TN的平均去除率为42.5%。蓄水陶土作为一种新型环保材料,可以广泛地应用于城市雨水面源污染的治理工程之中。Using a new urban rainwater storage material,called water storage pottery clay,as adsorption medium,the effects of adsorption and rejection of rainwater non-point pollutants from the city main trunk in Wuhan and rainwater purification by the water storage pottery clay were investigated.The results show that the removal rate of SS is more than 50%,the highest removal rate of COD is 53.8%,and the average removal rates of TP and TN are 43.2% and 42.5% respectively.Therefore,as a new environmental protection material, the water storage pottery clay can be widely used in the control engineering of urban rainwater non-point pollution.
