摘要: Abstract Anode potential is a critical factor in the biodegradation of organics bioelectrochemical systems (BESs), but research on these with complex recalcitrant co-substrates at set anode potentials scarce. In this study, carbamazepine (CBZ) BES was examined over wide range (−200 to +600 mV vs Ag/AgCl). Current generation and current densities were improved increase positive potentials. However, negative (−200 mV), higher as compared that for +000 +200 mV. The highest CBZ degradation (84%) TOC removal efficiency (70%) achieved +400 mV. At +600 mV, decrease observed, which can be attributed low number active bacteria poor ability adapt high voltage. This study signified BESs operated optimum could used enhancing contaminants environment.
