The start-up procedures, the degradation efficiency of organics at the anode and the removal efficiency of Cu²⁺ at the cathode of the cell were studied, based on which the performance of MFC (microbial fuel cell) in electricity generation and wastewater treatment was evaluated. A simple two-chamber microbial fuel cell was established with simulated molasses wastewater as substrate at the anode and simulated electroplating wastewater as an electron acceptor at the cathode. The results from a batch of experiments showed that the highest voltage output of 417.00 mV was obtained at an external resistance of 800 Ω,and that the maximum power density of 44.17 mW·m^-2was obtained with an internal resistance of 293 Ω based on the polarization curve. In addition, COD removal rate reached its highest value (47.31%) in the fifth cycle, and the maximum removal rate (59.76%) for Cu²⁺ was recorded in the fourth cycle. In summary, the application of MFC in the treatment of organic wastewater and electroplating wastewater is feasible.
