The Comparison of Substrate Changes in Microbial Fuel Cells Using Excess Sludge and Simple Anaerobic Digestion

Article Preview

Abstract:

Based on the previous studies, this experiment presented a new kind of microbial fuel cells (MFC), single-chamber air cathode microbial fuel cells without proton membrane. After investigating the contrast of substrate changes in microbial fuel cells and simple anaerobic digestion, the analysis results of soluble chemical oxygen demand (SCOD), TP, TN and NH3-N show that: SCOD increase firstly, then decrease, to the end, descend. As a result, we find that SCOD in MFC is lower than that in control device (CD). Throughout the whole reaction period, TP in MFC is lower than that in CD. TN and NH3-N show upward trend after a reaction period.
