摘要

分析了有机污染物在土壤中的迁移转化机理，建立了非平衡吸附作用下渗滤液中有机污染物在土壤中迁移转化的动力学模型，给出了模型的数值解法，模拟出渗滤液在非平衡吸附作用下的污染过程；同时还探讨了模型参数降雨量p，垃圾土土层的厚度h，含水率? 等对有机污染物运移的影响。结果表明：在总的污染源一定的情况下，降雨量的增大和污染土层厚度的增大会使得下层土壤中有机物的浓度降低，为定量研究有机污染物在土壤-水环境系统中分配与归宿提供理论依据，同时也可为监测、治理和恢复地下水污染提供一定的科学根据。

Abstract

The transportation and migration mechanism of organic contaminants in the soil was analyzed. Based on the above

a model of non-equilibrium adsorption dynamics behavior of organic contaminants transport has been established; and the numerical method of solving the optimization model has been presented. The model is used to predict the contaminated process of leachate transport. The effects of the parameters such as rainfall

layer of garbage

rate of water content in model are studied. In conclusion

under the certain pollutant source

the enlargement of rainfall and pollution soil layer will reduce the content of the organic contaminants of the soil in bottom layer. It provides theory evidence for quantitatively studying distribution and inclination of organic pollutants transport in soil-water environment. The reliable evidence is given to monitor

manage and recovery the pollution of groundwater. The potential pollution should be paid more attention to.
