摘要
在对我国南方某大型尾矿库库区水文地质条件概化的基础上 ,运用国际最新版本的三维地下水流动与污染物运移的模拟软件VisualMODFLOW建立了研究区U(Ⅵ )在浅层地下水系统中迁移的反应 -输运耦合模型 ,讨论了不同条件下U(Ⅵ )在地下水中的迁移情况 .模拟结果指示 ,在不治理的条件下 ,U(Ⅵ )对库区地下水污染严重 ;而在尾矿库治理条件下 ,由于地下水系统的自净作用 ,对于尾矿库在运营期间下渗的U(Ⅵ ) ,地下水系统完全可以“消化” .
The coupled reaction transport modeling of uranium(Ⅵ) in shallow groundwater was created on the basis of the hydrogeological pattern for a huge uranium gangue site in southern China. The software Visual MODFLOW, the most up to date simulation of the three dimensional groundwater flow and pollutant migration, was used to simulate the migration of uranium(Ⅵ) in groundwater on different conditions. As shown in the simulated results, the uranium(Ⅵ) would seriously pollute the groundwater without remediation. On the other hand, the uranium(Ⅵ) that arises in the operation of the uranium gangue would be completely “digested” due to the self remediation of groundwater when the uranium gangue is being brought under control.
