摘要
土壤既是大气汞与水体汞的汇,又是汞再次释放的源。土壤汞最终通过迁移等方式进入周边环境,危害人体和动植物的健康。综述了传统的汞污染场地修复技术,总结了热解析技术的影响因素、添加剂的协同处理以及热解前后土壤形态变化等,并对热解析技术处理汞污染土壤所存在的问题以及后续发展进行了展望。
The soil is the confluence of the mercury in the atmosphere and water environment,but also the source of the mercury releasing. The mercury in the soil will finally migrate into the surrounding environment,and damage human body and the whole ecosystem. In this paper,we reviewed the traditional contaminated site remediation technologies,summed up the factors affecting the thermal desorption technology,additive synergistic treatment and morphological changes of mercury in the soil. Finally,we put forward the prospect of the thermal desorption technology processing the mercury pollution of soil in the existing problems.
