    摘要:

    [目的] 揭示雨水回灌中污染物在深层承压含水层中的迁移扩散规律。[方法] 以常规指标氯化物(Cl-)为研究对象,针对天津市市区第Ⅳ承压含水组,应用地下水模拟软件(groundwater modeling system,GMS)中的MODFLOW和MT3DMS模块分别进行地下水流场和溶质迁移模拟。模拟了4种不同的Cl-质量浓度和水量条件对溶质运移的影响。[结果] 当溶质质量浓度相同时,回灌水量增大4倍,等Cl-浓度面积增大约1.44倍;当回灌水量相同时,溶质质量浓度增大2倍时,等Cl-浓度面积增大约0.92倍。[结论] 回灌水溶质浓度和回灌水量对Cl-在地下水中的迁移均有一定的影响,而且回灌水量的影响大于溶质质量浓度的影响;增大回灌水量、减小回灌水溶质浓度利于Cl-的迁移扩散。

    Abstract:

    [Objective] To analyze the contaminant transport of stormwater recharge in deep confined aquifer.[Methods] The groundwater flow modeling and solute transport simulation were studied by the Modflow and MT3DMS, which are two modules of groundwater modeling system (GMS), in the fourth confined aquifer of Tianjin City. And chloride ion(Cl-), a common index, was used as object of the study. Four different kinds of the mass concentrations of Cl- and the amounts of recharge water were simulated and analyzed.[Results] When the amount of recharge water increased 4 times and the solute concentration remained constant, the area of certain Cl- concentration in the groundwater would increases 1.44 times; when the solute concentration increased 2 times and the amount of recharge water remained constant, the area of certain Cl- concentration in the groundwater would increases 0.92 times.[Conclusion] Both the amount of recharge water and the mass concentration influence the transportation of Cl- obviously, and the influence of the former tends to be greater than the latter. Meanwhile, either increasing the amounts of recharge water or reducing the solute concentrations are conducive to transferring and diffusing of Cl-.
