摘要：

该文综述了高密度非水相液体（dense non-aqueous phase liquids，DNAPLs）的主要成分、种类、形成及迁移特征。通过分析DNAPLs空间分布、相分配特征和污染地块生命周期特点，总结了DNAPLs在地下的常见迁移行为。其次，综述了针对DNAPLs污染物的最新判定调查技术及其进展，介绍了判定DNAPLs存在的方法原理和用于探测DNAPLs分布范围的最新技术手段，有助于在DNAPLs污染场地选择适宜的调查方法，并对后续准确确定DNAPLs分布范围、制定经济高效的修复技术方案提供重要依据。

关键词: DNAPLs, 迁移特征, 相分配, 判定调查技术

Abstract:

The main constituents, types, origins and migration characteristics of DNAPLs (dense non-Aqueous phase liquids) were summarized. By introducing the characteristics of spatial distribution, phase partitioning and fate of DNAPLs at contaminated sites, the migration characteristics of DNAPLs were revealed. The advances of the latest investigation technologies of DNAPLs contaminants were reviewed. The principles for determining the presence of DNAPLs and the latest technologies for detecting the distribution of DNAPLs were introduced to offer a reference for determining the proper investigation method for DNAPLs sites, which would benefit a more precise scoping of DNAPLs distribution, as well as the development of cost-effective remedial plans.

Key words: DNAPLs, migration characteristics, phase partitioning, investigation technology
