Constructed wetland (CW) is an effective ecological technology to treat water pollution and has the significant advantages of high impact resistance, simple construction process, and low maintenance cost. However, under extreme conditions such as low temperature, high salt concentration, and multiple types of pollutants, some bottlenecks exist, including the difficulty in improving operating efficiency and the low pollutant removal rate. Microbial electrochemical technology is an emerging clean energy technology and has the similar structure and pollutant removal mechanism to CW. Microbial electrochemistry combined with CW can improve the overall removal effect of pollutants in wetlands. This review summarizes characterization methods of microbial electrochemistry-enhanced constructed wetland systems, construction methods of different composite systems, mechanisms of single and composite systems, and removal effects of composite systems on different pollutants in water bodies. Based on the shortcomings of existing studies, the potential breakthroughs in microbial electrochemistry-enhanced constructed wetlands are proposed for developing the optimization solution of constructed wetlands.
人工湿地（CW）是一种处理水污染的有效生态技术，具有抗冲击性强、建设工艺简单、维护成本低等显著优点。然而，在低温、高盐浓度和多种污染物等极端条件下，存在一些瓶颈问题，包括提高运行效率困难和污染物去除率低等。微生物电化学技术是一种新兴的清洁能源技术，其结构和污染物去除机制与人工湿地相似。微生物电化学与人工湿地相结合可以提高湿地中污染物的整体去除效果。本文综述了微生物电化学强化人工湿地系统的表征方法、不同复合系统的构建方法、单一和复合系统的作用机制以及复合系统对水体中不同污染物的去除效果。基于现有研究的不足，提出了微生物电化学强化人工湿地的潜在突破点，以开发人工湿地的优化解决方案。
