Sustainable Electricity Generation from Continuous Microbial Fuel Cells

摘要

The microbial fuel cell(MFC)is a device for wastewater treatment with simultaneous power generation.As batch-mode MFCs are common,the present research work reports on two trials of continuous mode operation of MFCs using domestic wastewater as substrate and sludge as bacterial source.Trial-2 was carried out with low substrate flow rate.The maximum chemical oxygen demand(COD)reduction during substrate treatment in trial-1 and 2 was determined.Though the average power output was high in trial-1,it had a drastically changing trend.Trial-2 provided better water treatment and non-fluctuating power output.Thus,it is favorable considering sustainable electricity generation.
