| Outline of Final Research Achievements |
A hybrid-type novel nitrogen removal system was developed by combining “microbial fuel cell” and “ammonia electrolysis”. The wastewater was treated by microbial fuel cells first, and then was treated by an ammonia electrolysis cell. By electrically connecting the microbial fuel cells and the ammonia electrolysis cell in series, ammonia was electrically removed from the wastewater only by electrical power generated by the microbial fuel cells, and nitrogen removal efficiency was increased compared with the treatment only by the microbial cells. Since ammonia is electrically oxidized to nitrogen gas, aeration energy for biological nitrification is not required in this system. Moreover, since electrolysis energy is supplied by microbial fuel cells, external energy input is not necessary.
