摘要
以溶质运移理论为基础,分析了酸性矿井水在含水层中运移的规律,通过室内土柱实验模拟了酸性矿井水对地下水污染的动态过程,并结合实际观测数据进行对比分析。结果表明:污染面积随时间推移不断扩大,且纵向扩散显著;不同组分由于各自特征的巨大差异,污染程度也有很大差别。本文的研究对预测预报酸性矿井水迁移归宿、评价环境质量、资源化利用以及环境污染的治理与控制等具有重要的理论意义和现实意义。
On the basis of solute transport theory, the mechanism of acid mine drainage in the aquifer has been analyzed. The process of acid mine drainage is presented by the soil pillar experiment that is don indoor and take a analysis for practice observation data. The result indicates that the contaminated plume is continually extended as time increases, and the vertical diffu sion is more abvious. The concentration distribution of contaminant is subtle to variation of fluid transport, and fluid density can have various effect on different solutes, becauce their character are different from each other. The research in this paper has theoretical and practical signifieance to predict the transport and transformation law of acid mine drainage, evaluate environmental quality, resources and control environmental pollution.
