| Outline of Final Research Achievements |
The characteristics of denitrification in paddy and agricultural drainage channel ware investigated. Nitrogen is released from the channel as much as tidal lands known as active denitrification and the contribution to natural purification of water is recognized. In the paddy we tried to control the activation of denitrification by controlling redox using microbial fuel cell application. The emission of dinitrogen monoxide from the pot with the circuit under acetylene inhibition method decreases by 65% compared with non-circuit one. On the other hand, remarkable effect was not found when introducing external voltage to enhance the control ability, because the effect on redox spread only near the electrode.
