Abstract:The Bureau of Sewerage is developing technology for reducing the generation of N2O during wastewater treatment to counteract greenhouse gas emissions.Although it is known that the reaction tanks and other tanks working in wastewater treatment generate N2O, it has not been known yet what effect, if any, different processing methods, operating conditions and other factors have on the generation of N2O.We have conducted a survey at an experimental wastewater treatment plant on what differences in processing methods, operating conditions and other factors have on the generation of N2O, we report our findings here on the dissolution of N2O in an anaerobic environment, the relationship between N2O generation and nitrite nitrogen concentration, and N2O generation at the second sedimentation tank.
