| Abstract |
All human activities generate wastewater that contains organic matters which need biological treatments. Microbial electrolysis cells (MECs) are suitable systems for wastewater treatment in that they can simultaneously produce gaseous fuels such as hydrogen or methane while decomposing organic matters. The microbial biofilm on the anode surface converts organic substances into carbon dioxides, protons, and electrons. On the cathode, protons and electrons combine to form hydrogen with voltage bias. Here we report our preliminary results in producing hydrogen from wastewater using a photo-assisted MECs (PAMECs) equipping p-type Cu2O as a cathode. The PAMECs were operated under visible light illumination at various voltage biases. When acetate was used as a fuel, exclusively hydrogen was produced. However, when a real wastewater collected from a Korea traditional alcoholic beverage factory was fed into the PAMECs, the PAMEC performance was lower than when acetate was used. These results show the possibility of PAMEC as a hydrogen-producing device while treating wastewater. |
