污染物在多孔介质中的传输过程,不仅是地下水渗流场和浓度场相互耦合的问题,而且介质的变形及内部温度的改变对污染物浓度的分布起着重要的控制作用,是一个多场耦合动力学问题。论述了污染物在多孔介质中运移的几类环境污染问题,并对引发环境污染的地质环境因素进行研究和分析,初步探讨污染物在多孔介质中迁移转化的动力学行为,详细阐述了多场耦合理论在污染物运移过程中的应用,并提出需要进一步解决的问题。
The transport of pollutants in porous media is not only the problem of coupled coupling of groundwater seepage field and concentration field, but also the deformation of media and the change of internal temperature play an important role in controlling the concentration distribution of pollutants. It is a multi-field coupling Kinetic problems. Several kinds of environmental pollution problems of contaminants migration in porous media are discussed. The geological and environmental factors that cause environmental pollution are also studied and analyzed. The kinetic behavior of pollutants migration and transformation in porous media is discussed in detail. The application of field coupling theory in the process of pollutant transport, and put forward the problems that need to be further solved.
