摘　　要：针对造成水体污染的城市降雨地表径流问题,建立模拟降雨系统,选用聚合物与功能材料,改良土壤结构,提高土壤对雨水的渗透性,削减地表径流及径流携带污染物对纳污水体的污染.结果表明,复合施用PAM与沸石使降雨径流过流体土壤结构被改良,对降雨径流的削减作用明显,对土壤的降水渗透有显著的促进.数据表明,沸石与PAM配施对削减降雨地表径流与提高降雨土壤入渗的效果有协同作用.在36、72和108 mm/h不同降雨强度下,处理土壤水的入渗较对照分别提高了35%～76%、32%～66%和18%～47%,降雨后土壤的含水量较对照可提高1～5倍.The research on minifying non-point source pollution in urban areas from runoff was accomplished setting a installation provided with simulation rainfall using PAM and functional materials of zeolite to improve the soil. The results show that the capability of the soil was mended, the output of runoff was obviously diminished and infiltration was advanced. With the rainfall intensities of 36 mm/h,72 mm/h, 108 mm/h,the infiltrations of the soils treated with different materials were increased by 35%～ 76% ,32% -66% and 18% -47% respectively and the contents of water in the soil were increased by 1 to 5 times compared with unsettled. The synergist effects to depress the runoff from rainfall were more promoted by PAM and zeolite.
