摘要
挥发性有机物作为污染场地中的主要污染物,由于其独特的污染特性,已成为当前环境领域研究的热点问题。鉴于挥发性有机污染场地情况和修复技术的多样性与复杂性,本文结合某挥发性有机物污染场地,给出多种复技术与工程控制的组合方法,同时结合场地特点,对比经济、技术、修复周期、环境风险等多项指标,最终确定了适合项目开发污染土源清挖+异位常温热解吸/热脱附+工程控制最优方案,阐述了VOCs污染场地修复技术筛选要点。
The remediation of VOCs,which is one of the main pollutants of contaminated sites,has become hot issues in modern environment field.Considering the diversity and complexity of the situation of sites and remediation technology,this paper provides a program of multiple remediation technology and engineering control for certain VOCs contaminated sites.The ultimate program is a combination of excavation of contaminated soil,ex-situ room temperature thermal desorption and engineering control,considering the characteristics of site,Economic,technological,remediation period,and environmental risk.Key points of the selection of remediation technology are summarized and discussed systematically.
