Abstract
A tubular microbial fuel cell (T-MFC) was used to remove benzene and toluene from groundwater with a great contaminant removal and power production efficiency. The main results were that T-MFC can completely degrade 200 mg/L toluene in 10 days under closed-circuit (CC) conditions, with a removal efficiency (RE) that is 38.2% greater than under open circuit (OC) conditions. When toluene and benzene were used as co-contaminants and a carbonized porous ceramic ring (CPCR) was added to the T-MFC cathode, the RE reached 100% within 6 days and the power density reached 15.6 W/m3. The radius of influence for 100% contaminant removal was 6 cm when the CPCR was added to the T-MFC cathode with a composite carbon source. The exoelectrogens Geobacter and Thermincola were the main species on the anodic surface, while the toluene-degrading bacteria Rhodocyclaceae dominated in the anode solution. This T-MFC is an innovative technology for the bioremediation of soil and groundwater that is contaminated by aromatic compounds, and has the potential to be used as a green energy device in the field.
