本试验通过模拟野外河滩土壤渗滤，分析测定原水和渗滤出水水质重金属浓度，研究天然土壤和填充碎石、沸石、活性炭、陶粒的土壤组合介质对水中重金属浓度的去除效果。结果表明：天然土壤和填充碎石、沸石、陶粒的土壤组合介质对河水中Hg的平均去除率分别为73．3％、49．4％、25．0％、75．0％。填充沸石的土壤组合介质在运行15天左右对河水中Cd的去除率也能达到30％。

The removal efficiency of heavy - metals in contaminative river by the infiltration of natural soil and soil combined medium filled by one of the four fillings （ gravel, zeolite, activated carbon and haydite） has been studied. Infiltrating experiment imitating the soil in river shoal has been carried on, and the heavy metal concentration of raw and infiltrated water has been tested. It show that the average removal rate of mercury by natural soil and soil combined media filled with gravel, zeolite and haydite is 73.3% ,49.4% ,25.0% ,75.0%. The removal rate of cadmium by soil combined medium filled with zeolite can reach to 30% after operated for 15 days.
