摘　　要：大唐延安发电厂在运行过程中可能对地下水环境产生影响,针对该问题建立了地下水流和溶质运移的水文地质概念模型、数学模型和数值模型,设置了3种预测情景并给出了泄漏量的计算方法,最终对高锰酸盐指数、Cl^-和F^-的运移情况进行了预测与评价。结果表明:3种特征污染因子在一定范围、一定时期内均有超标现象,但超标范围小且均未影响到保护目标,随着防渗破损处得到修复,地下水污染情况受到良好控制,因此对地下水环境影响不大。The groundwater environment may be affected by the operation of Yan＇an Power Plant,Datang. Hydrogeological model,mathematical model and numerical model about the groundwater flow and solute transport were established for this problem. Three prediction scenarios were set and methods for calculating the leakage were given,and the migration of CODMn,Cl^- and F^- were predicted and assessed respectively. Results indicated that the three characteristics pollution factors all exceeded the standard in certain period and scope,but the scope that exceeding the standard were small and did not affect the protection goals. Along with the remediation of the seepage,the situation of groundwater pollution was better controlled and consequently there has little impact on groundwater environment.
