To examine the importance of certain conditions on the production of nitrous oxide during denitrifications batch experiments with activated sludge were conducted. With the obtained parameters and a Monod kinetics based model the nitrous oxide concentrations in a CSRT were calculated. The influence of temperature, pH, nitrate influent concentration, readily biodegradable COD influent concentration, H2S and oxygen inhibitor concentrations are discussed. The presented model helps in understanding some previously described phenomena of nitrous oxide production in wastewater treatment plants.
