| 520 | 3 | |a A novel bioelectrochemical system (BES) operated with polarity reversion was explored for simultaneous anaerobic/aerobic treatment of azo dye and production of bioelectricity under extremely low buffer. The Congo red was first decolorized in anode, with completed color removal in 35h. The resultant decolorization intermediates were then mineralized after the anode reversed to aerobic biocathode, evidenced by 55% chemical oxygen demand (COD) removal in 200h. The mineralization efficiency was further increased to 70% when the period of the half-cycle was prolonged to 375h. Meanwhile, the BES produced a continuous stable positive/negative alternate voltage output under 5mM phosphate buffer because of the self-neutralization of the accumulated protons and hydroxyl ions in electrolyte. The electrode performance was significantly improved, which was indicated by alleviated electrode polarization, due to in situ use of accumulated protons and hydroxyl ions and enhanced electron transfer in the presence of Congo red and its degradation intermediates, which resulted in 1.05-fold increases in maximum power density (67.5 vs. 32.9mW/m2). An analysis of the microbial diversity in the biofilm revealed that the biofilm was dominated by facultative bacteria with functional roles in contaminant degradation and electricity generation. | |
