摘要
本文通过广州某冶炼厂在建项目为例,通过地下水污染概念模型,采用GMS模拟软件,构建了地下水污染迁移模型。结果显示,模型能够真实的反应场地实际水文地质条件,通过无防渗措施及事故工况下水质污染预测,确定了污染源CODCr、NH3-N、Pb的扩算范围,可以作为地下水环境影响评价依据。
This paper takes the construction project of a smelter in Guangzhou as an example. Through the conceptual model of groundwater pollution, the GMS simulation software is used to construct the groundwater pollution migration model. The results show that the model can truly reflect the actual hydrogeological conditions of the site. The anti-seepage measures and the prediction of water pollution under accident conditions determine the expansion range of CODCr, NH3-N and Pb, which can be used as the basis for groundwater environmental impact assessment.
