| 摘 要： | 通过构建二维非均质砂箱试验模拟垃圾渗滤液污染物在土壤-地下水环境中的运移，得出了渗滤液中Cl^-、SO4^2-、总硬度（CaCO3）在地下环境中的迁移和时空分布规律，同时引入一维土柱试验的结果与二维试验结果作了比较，表明二维砂箱中由于所模拟地下水的作用而使两者的污染物运移规律差异较大，这为预测和控制渗滤液污染土壤．地下水提供了一定的理论依据和试验方法。

| Abstract: | Through simulating the contaminant transport of the landfill leachate under the soil-groundwater conditions by the experiment with the two-dimensional heterogeneous sand chamber, the transport and space-time distribution laws of Cl^-, SO4^2- and CaCO3 in the leachate in the underground environment are obtained. The comparison between the results from 1D soil column experiment and the results from the 2D sand chamber experiment shows that the laws of contaminant transport are quite different between the results owing to the effect of the simulation groundwater in 2D conditions,which provides the theoretical basis and the approach to predict and control the pollution of the soil and underground water from the leachate. |
