摘要
介绍了一种国内环保领域鲜有提及的土壤及地下水中的重非水相液体污染即:DNAPL污染,并以三氯乙烯(TCE)和四氯乙烯(PCE)为例阐述了其产生来源、危害及污染行为。针对DNAPL污染,详细论述了零价铁墙防治原理、降解途径及其主要的影响因素。
In China, relatively few reported works have dealt with dense non aqueous phase liquid （DNAPL） pollution, which usually occurs in soil and underground water. This paper introduced the source, negative effects and characteristics of DNAPL pollution, especially in the cases of trichloroethylene （TCE） and perchloroethylene （PCE）. Zero-valent iron barrier technology was commonly used to prevent such pollution. Subsequently, the mechanisms, degradable paths and main factors were discussed.
