摘　　要：用数值模拟法研究有机污染物在土壤地下水中迁移转化预测极其重要,以太原市某粗苯深加工和储存遗留地块为研究对象,结合Hydrus与Modflow,模拟污染因子苯在包气带和饱和带的迁移转化路径。结果表明,纵向上苯在9年后迁移至地下水,模拟结果与实际观测相符;水平方向上,苯进入地下水后经5年迁移,影响面积约2911 m^(2),未超出厂区下游边界,同实际观测结果。案例表明Hydrus与Modflow综合模拟方法在有机污染物迁移转化过程中具有较强的可操作性,实现从包气带到地下水系统的全过程模拟,提高模拟精度和效率,降低治理成本,对环境治理工作具有较高的指导意义。The numerical simulation method is crucial for predicting the migration and transformation of organic pollutants in soil and groundwater.This study focuses on a site in Taiyuan City,which involves the deep processing and storage of crude benzene,and combines Hydrus and Modflow to simulate the migration and transformation pathways of the pollutant benzene in the unsaturated and saturated zones.The results show that,vertically,benzene migrates to the groundwater after 9 years,and the simulation results match actual observations.Horizontally,after entering the groundwater,benzene migrates for 5 years,affecting an area of about 2911 m^(2),without exceeding the downstream boundary of the factory,consistent with actual observations.The case study demonstrates that the integrated simulation method of Hydrus and Modflow is highly operable in the migration and transformation process of organic pollutants.It enables a full-process simulation from the unsaturated zone to the groundwater system,improving simulation accuracy and efficiency while reducing remediation costs,offering significant guidance for environmental remediation efforts.
