| Outline of Final Research Achievements |
Microbial fuel cell(MFC) is expected that it can establish a new wastewater treatment system which can accomplish electricity generation as well as wastewater treatment. However, concentration of organic carbon in domestic wastewater such as sewage is usually low for enough electricity generation by MFC, and practical application to sewage treatment has not been attained. MFC is driven by special microbes such as Geobacter which can construct electrical circuit, therefore improvement of electrical circuit condition can change the microbial community and MFC efficiency. In this study, addition of activated carbon is considered for attached growth media which can conduct electricity. It is observed that addition of activated carbon can attain both wastewater treatment and electricity generation, which suggests possibility of new wastewater treatment system with energy recovery and low sludge production.
