Vertical up-flow-constructed wetlands integrating with microbial fuel cell (VFCW-MFC) were evaluated for-N removal and bioelectricity recovery. The experiments were carried out in lab-scale VFCW-MFC microcosms treating synthetic domestic wastewater under different operational conditions of pH, hydraulic retention time, and mass loading rate. Effects of wild ornamental grass ( Cenchrus setaceus ) on treatment performance and voltage output were investigated simultaneously. Experiments demonstrated that the neutral pH of influents favoured-N removal and power generation. Extended retention time improved treatment capacity and power output but likely depended on the substrate availability. COD removal and power output increased, while-N removal decreased with increasing mass loading rates. At the loading rate of 88.31 mg COD/L.day, planted VFCW-MFCs exhibited better-N treatment performance (36.9%) and higher voltage output (132%–143%) than unplanted systems. Plants did not affect the COD removal efficiency of VFCW-MFCs (&gt;95%). Power density was in the range of 1.26–1.59 mW/m 2  in planted microcosms with a maximum CE of 13.6%. The anode layer accounted for a major proportion of-N removal in VFCW-MFCs. This study implies that-N in domestic wastewaters with relatively high COD:N ratios can be treated effectively in up-flow CW-MFCs via anaerobic processes, including anammox and heterotrophic denitrifying processes. The mass loading rate could be a critical parameter to balance different microbial processes, thus, coincidently determining the potential of power recovery from wastewaters.
