Abstract: The microbial fuel cell was made with the activated sludge as a simulated domestic wastewaterfrom the anaerobic tank of one reclaimed water treatment station. The paper applies microbial fuel cell totreat domestic wastewater and generates electricity, which can realize the recovery and utilization of ener-gy while treating wastewater. The results show that when the glucose concentration is controlled at10 mmol · L^-1 and the temperature is at 35 °C , it has the best electrochemical performance. The outputvoltage is 0. 326 V, the holding time is 1 120 min, the maximum output power density is 846. 87, the internal resistance is 240 Ω , and the COD removal rate is 46. 11% .
