Due to their limitations, conventionally constructed wetlands or microbial fuel cells often suffer from some disadvantages such as low denitrification efficiency, high internal resistance, and high activation potential in the process of treating nitrogenous wastewater. In recent years, the emerging constructed wetland-microbial fuel cell (CW-MFC) combines the constructed wetland (CW) and microbial fuel cell (MFC), which is a new bioelectrochemical technology for both electricity production and wastewater treatment, its natural redox gradient, unique cell structure, cathodic reduction characteristics and wetland plants located at the cathode not only provide advantages for nitrogen removal but also enhance the performance of electricity production. As a result of the diversity of wastewater types and their constituents, the effects of nitrogen removal from CW-MFC vary among different components. Most of the existing studies have investigated the effect of nitrogen removal in terms of system structure and composition, this paper reviews the effects of salinity and phosphorus in wastewater components on the denitrification performance of CW-MFC based on the analysis of nitrogen conversion pathways and nitrogen removal principles of CW-MFC, summarizes the problems caused by the limitations of the nitrogen removal process and the effects of salinity and phosphorus concentration, proposes ways as well as directions to strengthen the denitrification performance for the future development of CW-MFC.
