Continuous Electricity Generation with Piggery Wastewater Treatment Using an Anaerobic Baffled Stacking Microbial Fuel Cell
Anaerobic baffled stacking microbial fuel cells (ABSMFCs) consisting of four individual MFCs with total volume of 6.4 L was constructed to generate electricity from piggery wastewater in present study.Anode materials (carbon paper, carbon fiber felt and graphite granule) and anode connecting modes (in series or parallel) of the four MFCs could affect the bioelectricity generation and wastewater treatment effects.When they were connected in series, voltage loss occurred and voltage reversed at increased current between some MFCs.The influent COD loadings showed significant relative to the performance of ABSMFC, as it increased from 0.2 g/L·d to 4.0 g/L·d, voltage output across an extemal resistance of 1000 Ω decreased by 71.7% (in series) and 30.7% (in parallel); coulomb efficiency decreased rapidly by 96.7% (in series) and 943% (in parallel) while COD removal efficiency initially increased an then decreased.This study demonstrated that the large volume ABSMFC can realize stable power output associated with piggery wastewater treatment and is suitable to scale up for actual application.
