| 英文摘要 | Accelerated pollutant degradation was examined using a new combined chemical and bioelectrochemical system, called a Bio-E-Peroxone process, based on generating center dot OH from H2O2 produced on the cathode of a microbial fuel cell (MFC) and using ozone-enriched air. To optimize H2O2 formation, different carbonmaterials were examined and the highest H2O2 rates were obtained using XC-72 carbon black cathode. In E-Peroxone tests using the XC-72 cathode, methylene blue (a model pollutant) degradation rates followed first-order kinetics, with a rate constant of 0.237 min(-1), 6 times higher than that obtained using only ozonation (0.032 min(-1)), 15 times of electrolysis+O-2 system(0.015 min(-1)) and 46 times greater than electrolysis (0.005 min(-1)). In MFC tests when using the complete Bio-E-Peroxone system, the removal rate constant for methylene blue was 2.05 h(-1), compared to 1.86 h(-1) using only ozone and 0.41 h(-1) using only MFC. Adding ozone to the air in cathode also increased power production by 47% to 170 mW m(-3). The results demonstrated that this Bio-E-Peroxone system could be a feasible method for both refractory compounds degradation and wastewater electricity generation. (C) 2021 Elsevier B.V.
