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.

Key words: waste landfill leachate, organic contaminants, coupled dynamics and mathematics model, numerical modeling, non- equilibrium adsorption model
