气相抽提与氧化压裂技术结合在有机污染土壤修复工程中的应用

Application of gas phase extraction and oxidative fracturing technology in organic contaminated soil remediation engineering

本研究以退役农药污染场地修复实际工程为例,将原位气相抽提和高级氧化修复技术结合应用,并辅以水力压裂技术改善土壤渗透能力。设计制造了成套可移动、模块化修复系统和装备,通过小试、中试获得切实可行的系统化运行参数,为国内原位修复挥发性有机污染场地提供了可执行的技术指导和装备经验借鉴。

In this study,the actual project of remediation of decommissioned pesticide-contaminated sites is taken as an example.In situ gas phase extraction and advanced oxidative remediation technology are used in combination with hydraulic fracturing technology to improve soil permeability.Designed and manufactured a complete set of movable and modular repair systems and equipment,and obtained practical and systematic operating parameters through small and pilot tests,providing executable technical guidance and equipment experience for domestic in-situ repair of volatile organic pollution sites.
