异位热脱附技术在有机污染土壤场地中的应用

Application of Ex-situ Thermal Desorption Technology in Organic Contaminated Soil Sites

随着城市化进程的加快,环境保护越来越受到人们关注,大批污染企业被迫停业或拆迁,遗留的场地内存在大量有机污染,常规化学氧化已不能满足技术要求,需要采用修复效率高、周期短的异位热脱附技术。文章介绍了异位热脱附修复技术在有机污染场地中的应用,并结合场地概况、污染程度、工艺设计和修复效果,进一步分析了修复过程中遇到的有关问题,并提出了后续的改进方向,希望为相关热脱附修复项目中提供借鉴。

With the acceleration of urbanization,environmental protection has become a growing concern,a large number of polluting enterprises are forced to shut down or demolish,leaving behind numerous organic pollutants in the sites.Traditional chemical oxidation can no longer meet the technical requirements,and it is necessary to adopt ex-situ thermal desorption technology with high restoration eff iciency and short cycle.This paper introduces the application of ex-situ thermal desorption technology in organic contaminated sites,and further analyzes the relevant issues encountered during the restoration process,combined with the site overview,pollution degree,process design,and restoration effect.It also proposes subsequent improvement directions,hoping to provide reference for related thermal desorption restoration projects.
