| 摘 要： | 基于非饱和溶质运移理论,建立了水分运移和溶质对流-扩散的动力学耦合模型,通过室内土柱试验拟合了垃圾有机污染物衰减曲线,在充分考虑垃圾污染物浓度衰减,土壤水环境吸附解吸、生物降解作用基础上,进行了污染物运移的数值模拟,模拟结果较真实地反映了污染物的运移规律,该模型可为定量预测垃圾场土壤中有机污染物的时空分布提供一定的理论依据。

| Abstract: | On the basis of the theory of unsaturation solute transport, we have established the dynamic coupling model of moisture flow and solute advection-dispersion,fitted the damp curve of organic contaminants of landfill by laboratory soil column test. In full consideration of the concentration damping of landfill contaminants, sorption, desorption and biodegradation of solutes in soil and water environments, we have made a numerical simulation of contaminant transport. The simulation results truly reflect the la... |
