Research overview:
It is well known that nitrous oxide is emitted from wastewater treatment processes, and its green house effect potential is very higher than that of CO2 and CH4. Therefore, the controlling of nitrous oxide emission from nitrification and denitrification processes is an important subject from a viewpoint of global warming. Laboratory scale experiments using ammonia rich wastewater are performed to determine relationships among ORP/DO/pH, nitrification, denitrification and nitrous oxide production, and to develop a sensor aided SBR system, which achieves advanced nitrogen removal and reduction of N2O emission, simultaneously.
