摘要
为正确评价江苏长强钢铁厂拟建项目的建设运行对地下水环境的影响,在合理概化水文地质概念模型的基础上,构建了与之相应的地下水渗流和溶质运移的数值模型。通过对新建厂区运行20年的污染物运移情况进行数值模拟,确定出污染物扩散范围。结果表明,新建厂区周围地下水环境已受到污染,但影响范围及程度有限,平面上仅局限在厂区内,均未超过污染源下游100m;剖面上仅局限在潜水含水层及微承压孔隙含水层内,不涉及承压含水层。
In order to properly evaluate impacts on groundwater environment in the Changqiang Steel Mill from proposed project con-struction and operation, a corresponding groundwater seepage and solute transport numerical model has been modeled on the basis of reasonably generalized hydrogeological conceptual model. Based on the new factory area pollutant migration in 20 years has carried out numerical simulation to identify pollutant spread range. The result has shown that the groundwater environment around the new factory has been polluted, but the impact scope and degree are limited. View from the plane, polluted area is confined within factory area, no more than 100m downstream of the pollution sources;from the profile, polluted area is limited within the phreatic aquifer and slightly confined aquifer, while confined aquifer not involved.
