Abstract: The remediation technologies for soil heavy metal pollution were sorted out and summarized, which provided a reference for the subsequent treatment of soil heavy metal pollution. By using the form of literature review, the soil heavy metal remediation technologies were summarized, and then the problems and prospects were put forward. At present, the main application of soil heavy metal remediation technology was bioremediation, chemical remediation, physical remediation and combined remediation technology. These repair techniques could achieve good repair results in repairing the heavy metal pollution in soil. However, there were also some limitations. When carrying out the remediation of heavy metal pollution in soil, it was necessary to select the appropriate remediation technologies according to the specific conditions of different soils. The research conclusions included strengthening the follow-up research of remediation technology, controlling the pollution from the root causes and preventing the secondary pollution; considering the soil condition of the contaminated land, scientifically applying the soil heavy metal remediation technology; and flexibly selecting the combined repair technology according to the local conditions. Through the cooperation of different repair technologies, other problems arising in the repair process could be solved.
