摘要
重金属污染土壤的修复问题一直是国内外研究课题的难点。目前,对此类污染土壤的处理主要包括物理、化学、生物等修复方法,其中,物理法主要包括:客土法、换土法和深耕翻土法;而化学法主要包括:固定/稳定化技术、土壤淋洗技术和氧化还原技术;生物法主要包括植物修复和生物治理。基于以上方法,在重金属污染土壤的治理修复过程中,最常用的方法是利用物理和化学相结合的方式,主要是用换土法配合固化/稳定化技术。本研究主要对现场实际工程应用中的固化/稳定化技术进行了讨论。
Remediation of heavy metal contaminated soil has always been a difficult research topic at home and abroad.At present,the treatment of such contaminated soil mainly includes physical,chemical,biological and other remediation methods.Among them,physical methods mainly include:vip soil method,soil exchange method and deep tillage method;The chemical methods mainly include:fixation/stabilization technology,soil leaching technology and oxidation-reduction technology;Biological methods mainly include phytoremediation and biological treatment.Based on the above methods,in the process of remediation of heavy metal contaminated soil,the most commonly used method is the combination of physical and chemical methods,mainly soil exchange method and solidifi cation/stabilization technology.This study discusses the solidifi cation/stabilization techniques used in fi eld engineering applications.
