基于MODFLOW的废铅蓄电池对地下水污染模拟

Simulation of Groundwater Pollution Caused by Waste Lead Storage Battery Based on MODFLOW

以交城县一废旧物资回收有限公司为研究区,应用MODFLOW软件建立了地下水水流模型和溶质运移模型,模拟了废铅蓄电池中的有毒有害物质在人工防渗层破损非正常情况下的运移情况。数值模拟预测了污染物的影响范围、超标范围和最大运移距离。由预测结果可知,污染物主要沿水流方向运移,对水环境的影响随时间逐渐增大,硫酸盐对水环境的影响较大。

Taking a Waste Material Recycling Co.,Ltd.in Jiaocheng County as the research area,this paper established the groundwater flow model and solute transport model by using MODFLOW software to simulate the migration of toxic and hazardous substances in waste lead batteries under abnormal conditions of artificial impermeable layer damage.Numerical simulation pre-dicted the influence range,exceeding range and maximum migration distance of pollutants.It can be seen from the prediction results that pollutants mainly migrate in the direction of water flow,and their impact on the water environment gradually increases with time,and sulfate has a greater impact on the water environment.
