摘　　要：建立模拟降雨装置，研究降雨条件下功能性材料与聚合物对降水土壤渗透性与地表径流污染负荷的影响。研究证实，沸石与PAM不仅能够促进降雨土壤水的人渗、延缓并减少地表径流．而且使土壤渗液和地表径流水质TSS、TN、TP、COD污染物负荷降低。以3kg／hm^2PAM、3kgPAM与7．5t／hm^2沸石、6kg／hm^2 PAM3种方式处理，径流COD负荷为对照的39．12％-69．76％、26．14％-46．63％和20．60％-28.09％；TN、TP与TSS负荷较对照分别减少44．36％-96．47％、66．63％-98．99％、93．71％-99．62％和50．46％～98．40％、83．30％～99．3l％、94．91％～99．72％和31．06％～77．23％、46．82％，86．22％、83．54％-95.33％。聚合物与功能性材料改良土壤是一种削减地袁降雨径流非点源污染的有效手段。The researches on decreasing the pollution loads in rainfall runoff with PAM and functional materials of zeolite to improve the soil was accomplished using the simulated set. The results showed that the pollution loads of runoff and infiltration water in rainfall were decreased compared with untreated ones, the COD of runoff were 39.12% - 69.76% ,26. 14%- 46.63% ,20.60% - 28.09% and TN,TP and TSS were decreased 44. 36% -96.47%,66.63% -98.99%,93.71% -99.62% and 50.46% -98.40%, 83.30% -99.31%, 94. 91% -99.72% and 31.06% -77.23% ,46.82%-86.22%,83.54% -95.33% in the conditions of 3 kg PAM, 3 kg PAM ＋7.5 t zeolite and 6 kg PAM per hm^2 ,respectively. The results approved that the effect to decrease runoff and promoting infiltration in rainfall was enhanced using zeolite and PAM at one time.
