This paper summarizes the effects of materials commonly used for infiltration media in rainwater infiltration facilities, including natural materials ( e. g. , zeolite, silica sand, and wood) , waste materials ( e. g. , coal ash and crab shell) , and artificial materials ( e. g. , fibrous membranes, activated carbon, and zero-valent iron ) . The properties of different materials and the efficiency and mechanisms of the materials used as improved infiltration media to remove contaminants are analyzed and summarized. It is concluded that contaminants in the runoff, such as heavy metals and polycyclic aromatic hydrocarbons (PAHs), cannot be completely removed by ordinary infiltration materials such as soil. Improved infiltration media can not only control water pollution, but also enhance the efficiency of infiltration facilities and reduce congestion caused by infiltration media. Since each kind of material has its pros and cons, it is shown that, according to different rainwater qualities and treatment requirements, combining different materials as infiltration media or developing new materials may improve the efficiency of infiltration facilities.%综述常见的雨水渗滤设施中填料的作用，包括天然材料如沸石、石英砂、木料，废弃材料如煤灰渣、蟹壳，以及人工材料如纤维膜、活性炭和零价铁等；比较分析不同渗滤材料的特性及其用于改良渗滤层时对污染物的去除效果及去除机理，认为传统的渗滤材料(如土壤)难以去除径流雨水中的难降解污染物(如重金属、多环芳烃等)，而改良的渗滤材料不但可改善出水效果，且可提高设施处理效率，减少滤料层阻塞。由于不同渗滤材料各有利弊，针对不同的雨水水质及处理要求，多种渗滤材料的配合使用以及对新材料的开发将有益于提高雨水渗滤填料层的处理效果。
