In this study, batch experiments were conducted to investigate the removal of antibiotics in MECs treating concentrated sludge under different applied voltages. The enhanced antibiotics removal mechanism as well as the main contributors were analyzed through electrochemical performance and redox reactions of the system, the responses of suspended sludge microorganisms and electrode-attached microorganisms to different applied voltages. The removal efficiencies of antibiotics were 18.1-78.4%, while chlortetracycline and azithromycin were hardly removed. The removal efficiencies of antibiotics under the applied voltages of 0.6V and 1.0V was significantly higher than other groups (0.3V and 1.5V). |
