| 摘 要： | 文章以粘土和壤土为实验材料,研究两种不同土壤对渗滤液中COD、重金属含量的吸收净化效果。结果表明:相同高度的粘土比壤土吸附效果好,同一种土壤对pH、COD、重金属的去除效果随土层厚度的增加而增强。

| Abstract: | Soil with different textures including clay soil and loamy soil were used to attenuate leachate from Jiyuan Landfill in Jiaozuo City,Henan Province,for the purpose to study the purification effect of COD and heavy metals.Results showed that clay soil had higher capacity to remove COD and heavy metals than loamy soil in the same depth.It was also revealed that the purification efficiency of all soil columns decreased as the soil depth decreased. |

| Keywords: | landfill leachate soil purification removal efficiency of COD heavy metal |
