Soil contamination poses a serious threat to ecosystem and human well-being. Compared to conventional physical and chemical treatment, the microbial electrochemical system (MES) offers a sustainable and environment-friendly solution for soil bioremediation. In principle, soil microbe degrades organic substrate and releases electron in anode region. The electron flows through electric circuit to the cathode and finally is accepted by oxygen or oxidized metals. With various inherent advantages, MES has been applied in petroleum hydrocarbon, chlorinated organics and heavy metals bioremediation in soils. This paper aims to review the recent advances of MES in soil bioremediation, including main mechanisms of contaminant removal with MES, configurations of soil MES and current development in bioremediation of soil contaminated by organic and inorganic pollutants. Moreover, challenges and future prospects of soil MES are discussed.

土壤污染严重威胁着生态系统和人类福祉。与传统的物理和化学处理相比，微生物电化学系统（MES）为土壤生物修复提供了一种可持续且环保的解决方案。原则上，土壤微生物会降解有机基质并在阳极区域释放电子。电子通过电路流到阴极，最后被氧气或氧化的金属接受。MES具有各种固有的优势，已被应用于石油碳氢化合物，氯化有机物和土壤中的重金属生物修复。本文旨在综述MES在土壤生物修复中的最新进展，包括MES去除污染物的主要机理，MES的结构以及有机和无机污染物污染土壤的生物修复研究进展。此外，讨论了土壤MES的挑战和未来前景。
