| 摘 要： | 人工回灌技术在我国水资源管理中占据重要地位，但是其实施对地下水环境质量也造成了较大的影响。如何保障人工回灌条件下地下水环境质量的安全稳定性，已成为人工回灌技术发展的瓶颈。以上海市某人工回灌试验场为例，结合试验场的地质、水文地质勘探结果，以TOUGHREACT为数值模拟平台，模拟预测人工回灌条件下地下水中多组分溶质的迁移转化过程。模拟结果表明：地下水化学成分主要受混合作用、阳离子交换吸附作用及含水层矿物相溶解-沉淀作用等影响；含水介质中石英、白云石、钾长石、钠长石及蒙脱石发生溶解，方解石发生沉淀，伊利石与高岭石则先溶解后沉淀，但各矿物相反应量极其微弱；按不同压力方案回灌，水位恢复速率随压力增大而加快，但地下水中化学成分变化趋势几乎不受压力影响。 |

| Abstract: | Groundwater recharge is an important way of water management strategies,including the natural recharge and artificial recharge.The study of groundwater recharge test as Baoshan District of Shanghai for example,with preliminary geological,hydrogeological exploration results,the purpose of filtering out the appropriate level of recharge(the fourth aquifer),establishing of recharge test hydrogeological conceptual model accorded to the aquifer permeability,hydraulic gradient,the main mineral composition and other basic properties.Then take TOUGHREACT for the numerical simulation platform,which software of non-isothermal multiphase flow and transforming simulation,to predict the quality of groundwater after recharging.The results show that chemical composition of groundwater is mainly affected by mixing,cation exchange adsorption and dissolution of aquifer minerals and so on;water-rock interaction process of quartz,dolomite,feldspar,albite Stone and montmorillonite dissolves,calcite precipitation,illite and kaolinite precipitation is first dissolved,but the amount of mineral reaction and weak.Program at different pressure recharge,water level recovery rate with increasing of pressure,but the chemical composition of groundwater trends is almost free from pressure. |
| Keywords: | artificial recharge groundwater multi-component TOUGHREACT water-rock interaction |
