摘要
地下水中挥发性有机污染物的向上迁移能够对地面以上的人体健康造成威胁,在污染物向上迁移的过程中,毛细带对污染物的生物降解作用越来越受到人们的关注,在蒸汽入侵影响的模型计算中也开始加入由于毛细带的存在而引起的修正因子,但是目前毛细带对污染物的降解机理尚未有深入研究。对目前国内外有关毛细带的研究进行了较全面的综述,介绍了毛细带的定义及基本特征、污染物在毛细带内的迁移规律、微生物在毛细带的生长和分布情况、以及毛细带内有机污染物的生物降解等方面的研究进展,旨在通过对毛细带基础研究的综合分析,为进一步研究毛细带对污染物的降解机理提供研究基础。
The upward migration of volatile organic pollutants in groundwater can be a threat to the human health. In the process of upward migration of pollutants,people pay more attention to the capillary effect on the degradation of pollutants. In the model calculation of vapor intrusion influence,the correction factor caused by the capillary zone was taken into accountant.But there is no in-depth study on the mechanisms of the degradation of pollutants. Existing research about the capillary zone are introduced comprehensively here,and the research achievements in this field at home and abroad are summarized,focusing on research progress of the definition, essential characteristic, migration patterns, the growth and distribution of microorganisms,and the biodegradation of organic pollutant in the capillary zone. The purpose is to provide research foundation for the further study of degradation mechanism in the capillary fringe through the comprehensive analysis of the basic research.
