污染地块修复原位热脱附技术的研究及应用进展

Development and application of in situ thermal desorption for the remediation of contaminated sites

原位热脱技术是一种适合污染源或含NAPL相的重污染土壤和地下水的修复方法。本文通过对国内外资料进行调研,从热脱附修复技术发展历程、热脱附系统基本组成、热脱附修复污染地块的关键影响因素、热脱附修复机理、国内外原位热脱附技术相关专利以及典型应用案例等不同角度进行分析讨论,重点从污染地块修复工程应用角度分析其技术可行性,为原位热脱附修复技术发展提供支持。

In situ thermal desorption（ISTD）is a kind of suitable remediation technologies for the heavily contaminated site of polluting resources or NAPL in soil and groundwater. This paper focuses on introduction to ISTD development course,basic compositions of ISTD system,critical influencing factors of remediation with ISTD technology,ISTD remediation mechanism,domestic and international patents of ISTD technology and supporting equipment,typical application case studies and other perspectives. Based on the research of ISTD technology,this paper also emphasizes application feasibility and provides technology support.
