Petroleum extraction and transportation can generate large areas of petroleum contaminated sites.In the context of carbon neutrality,microbial electrochemical technology provides a novel low-carbon remediation strategy for the removal of petroleum organic pollutants from soils.Based on this,the operating principle and classification of microbial electrochemical systems were briefly introduced.The feasibility of applying this technology to the remediation of petroleum contaminated soil was specifically analysed with regard to the advantages of low cost,low carbon,high energy conversion efficiency and high controllability.Subsequently,the factors influencing the remediation performance of microbial electrochemical systems were outlined in detail,as well as the enhancement pathways such as increasing the electron acceptors,improving the mass transfer capacity and enhancing the electron transfer capacity of the systems were summarized.The current emerging problems and limitations of microbial electrochemical remediation technology were summarized,and it is suggested that future development should focus on microorganisms,reactors and practical applications in order to guide the practical application in contaminated soils.
