摘要
基于渗流和溶质运移理论,建立了垃圾渗滤液污染物运移的动力学耦合模型,将所建的模型在充分考虑土壤水环境吸附解吸、生物降解作用基础上,用于被垃圾渗滤液污染的PRB修复模拟研究,同时对比分析了有无PRB修复墙的两种情况下污染物的迁移规律和时空分布曲线,模拟结果较真实地反映了污染物的迁移特性,证明了所建模型的有效性,该模型可为定量预测PRB修复垃圾污染地下水中污染物的时空分布提供一定的理论依据。
Based on theory of seepage and solute transport, dynamic coupling model of transport of landfill leachate pollutant is established. The established model is used to study contaminant transport law of groundwater polluted by leachate in PRB modification model with and without PRB modification, on the basis of sorption, desorption and biodegradation in soil and water environment. The result reflects contaminant transport law truly, and proves validity of this model. The model provides the theoretical basis for quantitatively predicting space-time distribution of contaminant in PRB modification.
