摘要

为预测某规划区地下水环境影响,本次研究运用FEFLOW地下水数值模拟软件,在分析研究区水文地质、地下水渗流场等的基础上建立了溶质运移数值模型。模拟结果显示,模型能够真实反映研究区实际水文地质条件,预测两种工况下的氨氮、氰化物和COD进行溶质运移变化规律,可以作为地下水环境影响评价的依据。同时,污水处理厂在事故工况下对地下水环境影响较大,规划区应制定相应的地下水风险应急预案并采取严格的防渗措施,减小对地下水的影响。
        For predicting the influence of groundwater environment in a planning area, EFLOW groundwater numerical simulation software was used in this study, A solute transport model was obtained by integrating the analysis of hydrogeological profile, groundwater seepage, and solute transport equation in the studyarea. The simulation results showed that:(1) The model can truly reflect the hydrogeological conditions inthe study area, and predict the solute transport changes of ammonia nitrogen, cyanide and COD under twoconditions, which can be used as the basis for the groundwater of environmental impact assessment.(2) Itwas concluded that the risk of groundwater contamination was raised in the event of an increase in pollutantsleakage under the accident condition, The planning area should make the corresponding emergency plan for the groundwater risk and adopt strict anti-seepage measures to reduce the impact on the groundwater.
