摘要
根据渗流理论,考虑地下水中水头变化的影响,利用COMSOL软件,对六价铬在地下水中的运移进行数值模拟,得到地下水压力水头和六价铬在地下水中的迁移变化规律,为六价铬对地下水的污染研究和预测提供重要的分析数据。并借此计算得出场地地下水的修复指导限值为3.17 mg/kg。
Chrome pollution is one of important factors affecting pollution of groundwater.Taking account of the effect of variable head on groundwater,numerical simulation of transportation and migration of hexavalent chromium is done by using COMSOL,and the changing law of migration of pressure head and hexavalent chromium in groundwater is given.It provides important analytical data for research on pollution and prediction of chrome pollution in groundwater.According to the calculations,the restoration value of Cr6 ＋ was 3.17 mg /kg for the groundwater.
