摘要
我国西南岩溶发育及分布面积十分广泛,准确预测及分析岩溶区地下水渗流和污染物迁移对这些地区地下水环境保护及管理非常关键。因此,本文以云南曲靖市沾益区某污水处理厂项目为例,通过详细开展水文地质调查及勘察,在查明拟建项目区所属水文地质单元及水文地质条件特征基础上开展地下水渗流和污染物迁移数值模拟研究。研究结果表明,处于特殊构造部位的项目场地地下水与地表水转换频繁,地表水体抑制了特征污染物扩散。
The development and distribution of karst zone in the southwest of China is very extensive.The accurate prediction and analysis of groundwater flow and contaminant transport in karst areas are very important for the environmental protection and management of groundwater in these areas.Therefore,a sewage treatment project in Zhanyi district of Qujing city,Yunnan province are taken as an example in this study.The detailed hydrogeological investigation and investigation are carried out.A numerical simulation study on groundwater flow and contaminant transport is conducted on the basis of identifying the hydrogeological unit and hydrogeological condition of the proposed project area.The results show that the transform between groundwater and surface water is frequently in the project site due to the special structure.The diffusion and transport of characteristic contaminants are controlled by the surface water body.
