| 摘 要： | 运用多孔介质溶质运移理论及水力学原理，建立了土壤中难降解有机污染物释放的动力学模型，并对其模型进行了解析求解，运用实验数据对模型进行了验证。计算结果表明：所建动力学模型能很好地反映土壤中难降解有机污染物释放的真实过程，准确地描述土壤固相释放时液相难降解有机污染物浓度变化的规律，为准确预测和预报污染物在土壤中的扩散状况以及环境污染的治理、防止二次污染提供了可靠的理论依据。

| Abstract: | The kinetic model for desorption of bio-refractory organic pollutants in soil is established with theories of transport of solute in porous media and hydraulics; and the analytical solution of the kinetic model is given. And the kinetic model is verified using data of experiments and parameters. The results show that the kinetic model is true in describing the desorption process of bio-refractory organic pollutants in soil and the change of bio-refractory organic pollutants concentration in water phase. In addition , the theory evidence is provided for forecasting diffusion of contaminants in soil, avoiding recontamination and pollution control. |
