Discussion about Cause of Nitrous Oxide (N2O) Emission in Wastewater Treatment Plant, Based on Long-Term Continuous Measurement
Abstract
The Bureau of Sewerage, Tokyo Metropolitan Government, has been implementing various measures to reduce greenhouse gas (GHG) emissions. However, measures to reduce Nitrous Oxide (N2O) emission from wastewater treatment, which amounts to about 16% of the GHG emission from the Bureau, has been delayed since little is known about its behaviors and factors which affect its emission.The Bureau installed continuous N2O analyzer in a wastewater treatment plant (WWTP), and conducted continuous measurement of N2O emission for one year. The results showed that N2O emission fluctuated significantly and was affected by nitrogen load of influent and nitrification condition in reaction tank.
