地下水污染已成为我国面临的一个极其严峻的环境问题,建立防污屏障控制地下水污染也就成为了研究的重点。文章在对国内外已有资料研究的基础上,对人工冻结的土体在隔离污染物中的应用进行综述。人工冻土在隔离污染物方面的应用主要有以下三点——作为低温屏障,处置固体废弃物和低温富集污染物。针对这三点应用,指出了目前国内外冻土隔离污染物方面存在的一些欠缺。最后对污染物在冻土中迁移研究现状进行总结,对新的研究领域进行展望,以期为污染物处置技术提供新的可能。
Groundwater pollution has become an extremely serious environmental problem that our country is facing. It has also become the focus of research to establish an anti-pollution barrier to control groundwater pollution. Based on the existing data research at home and abroad, the article reviews the application of artificial frozen soil in the isolation of pollutants. Artificial frozen soil in the isolation of pollutants in the application of the following three points - as a low temperature barrier, disposal of solid waste and enrichment of pollutants at low temperature. In view of these three applications, some shortcomings in the isolation of pollutants in frozen soil at home and abroad are pointed out. Finally, the status quo of the study on the migration of pollutants in frozen soil is summarized, and the prospect of new research fields is prospected in order to provide new possibilities for pollutant disposal technologies.
