水蚀性岩层中的渗流和无机污染物的迁移

介绍水蚀性岩层中的渗流及金属和无机污染物迁移问题．通过对含有污染物的某些蓄水系统中的物理和化学过程的分析得出一些结论，并对这些过程不仅作了详细的说明，而且采用恰当的数学和化学方程加以讨论．在水蚀性岩层中无机污染物的迁移用高渗透率多孔介质中流动的基本方程近似地描述，而对流、水动力学扩散、稀释等影响可作为物理过程来阐述．总的说来，控制裂隙岩体中地下水流动与污染物输运的物理和化学机理是建立水蚀性岩层中无机污染物输运近似方法的基础．

SEEPAGE FLOW AND MOVEMENT OF CONTAMINANTS IN KARSTIFIED CARBONATE ROCKS

in this paper, the dynamic flow systems and transport of contaminants in karstic aquifers are presented. Some conclusions are reached from the analysis of physical and chemical processes involving aqueous systems containing certain contaminants, Pertinent mathematical and chemical equations for these complicated processes are discussed. Contaminant transport in Karstic aquifers can be mathematically expressed by the basic equations evaluated primarily for the flow in porous, highly permeable aquifers. The effects of advection,hydrodynamic dispersion, and dilution are discussed as physical processes. To sumup, physical and chemical mechanisms that govern contaminant movement and ground water flow through fractured media are proposed as the basis of anapproximate approach of contaminant transport through karstified carbonate rocks.
