Abstract: Industrialization has promoted the prosperity of global oil industry. However, soil pollution caused by oil production and utilization is becoming more and more serious. The green, economical, stable and efficient remediation technology of petroleum polluted soil has been developed. Based on the present situation and the harm of petroleum contaminated soil, we summarized the existing physical, chemical, biological, and combined remediation technologies and remediation mechanisms of petroleum contaminated soil. Meanwhile, we expounded the applicable conditions, advantages, and disadvantages of different restoration methods. Finally, we prospected the future deve-lopment direction and challenge of remediation technology of petroleum contaminated soil. This work provides a reference for the research of remediation of petroleum contaminated soil and the selection of engineering application technology.

Key words: petroleum pollution, soil, remediation technology, total petroleum hydrocarbons, joint repair
