| Outline of Final Research Achievements |
A novel microbial fuel cell (MFC), capable of removing organic matter and nitrogen from wastewater, was proposed and demonstrated experimentally. The proposed MFC was two -chamber structure and was comprised of anodic compartment and a cathodic compartment equipped with both a denitrifying biocathode and an air-cathode on which nitrifying biofilm was pre-enriched (nitrifying air-cathode). In the cathode compartment, TN removal successfully proceeded through a sequence of biological nitrification by utilizing oxygen passed through the nitrifying air-cathode and autotrophic denitrification on the denitrifying biocathode with utilizing electrons delivered from anode as electron donors. Electric power was generated both between the nitrifying air-cathode and anode and between the denitrifying biocathode and anode during organic matter degradation in the anode compartment and TN removal in the cathode compartment.
