Application of combined remediation in heavy metal polluted soil

Abstract Whether it is single or compound heavy metal pollution, it is universal, complex, and invisible. The soil pollution cannot be completely resolved only relying on a single repair technology, requiring multiple approaches often. The combined remediation technologies of soil pollution can exert respective advantages, abandon their shortcomings, and optimize the repair effect. Based on a large number of literature surveys, this article discussed the application of combined remediation in heavy metal-contaminated soils, in order to provide reference for the rehabilitation of heavy metal-contaminated soils.
