尾矿库排放的重金属锌在厂区的迁移模拟分析

Migration Simulation Analysis of Heavy Metal Zinc in Plant Discharged from Tailing Pond

近年来,随着矿物的开采开发,对地下水造成了严重的污染,尤其是在选矿和尾矿堆放过程中。对方的尾矿经过淋漓作用释放出重金属,重金属淋漓液经渗透进入地下水造成地下水污染。本文在北衙某尾矿堆放场地下水环境影响调查及分析的基础上,建立研究区渗流模型及污染物迁移模型,在此基础上设定不同的污染情况并进行模拟分析。研究表明重金属锌的迁移主要受含水层性质、污染物泄漏事件以及防渗工程等因素影响。

In recent years,with the exploitation of mineral resources,groundwater has caused serious pollution,especially in theprocess of mineral processing and tailings stacking.The tailings releases heavy metals through the heavy rain,and the heavy metal liquidthrough infiltration into groundwater causes groundwater pollution.In this paper,based on groundwater environmental impact survey andanalysis a the Beiya tailings disposal site,it established the seepage model and pollutant transport model in the study area,and on the basis,set different pollution conditions and took a stimulation.
