摘要
以某污染厂区为研究对象,通过野外调查并结合已有资料,利用GMS软件建立研究区域地下水流场模型和溶质运移模型,并且详细分析了地下水污染规律。研究结果表明:降雨入渗扩散方式下,污染物在地下水中的迁移速率与污染物的浓度及地下水介质密切相关。在潜水含水层中,污染物主要以垂向运移为主,并且受污染源强影响较大,污染物浓度越高,其垂向运移速率越快,污染物在水平面上的扩散速率受污染源强的影响较小;在承压含水层中,污染物沿水流方向迁移,并且呈现匀速扩散趋势。
Taking a polluted factory as the research object,through field investigation and combining existing data,the model of underground flow field and solute transport in the research area was established by GMS software,and the law of groundwater pollution was analyzed in detail.The results show that the migration rate of pollutants in groundwater is closely related to the concentration of pollutants and groundwater media.The higher the pollutant concentration is,the faster the vertical migration rate will be.The diffusion rate of pollutants on the horizontal surface will be less affected by the strong pollution source.In the confined aquifer,the pollutant migrates in the direction of water flow and presents a uniform diffusion trend.
