| Abstract |
Microbial electrolysis cells (MECs) are a promising technology for wastewater treatment and the simultaneous production of energy gases such as hydrogen and methane. In most MEC studies, synthetic wastewater which contains pure compounds (acetate or glucose) as a substrate have been examined for effective hydrogen production. External voltage bias of 0.114 V or more must be applied to operate MECs due to the thermodynamic barrier for hydrogen production. To resolve this problem, we have developed a photo-assisted microbial electrolysis cell (PAMEC) for domestic wastewater treatment which consists of a bioanode and a p-type semiconductor photocathode. With an aid of solar energy, our PAMEC system continuously produced methane with 55 A/m3 current density with simultaneous COD removal of 66 % at 0.8 V of external applied voltage under visible light illumination. These results show the possibility of a PAMEC as a future energy source that produce hydrogen and methane from wastewaters. |
