Study on Solidifi cation/Stabilization Remediation Technology of HeavyMetal Contaminated Soil

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:guest 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.
