  • N2O is a potent greenhouse gas, and releases a lot in wastewater treatment. Understanding the influencing factors of N2O release in wastewater treatment can reduce N2O emissions. Four classical external organic carbon sources, such as sodium acetate, ethanol, glucose and sucrose, were used to study the N2O release process in denitrification process with SBR reactors. The results showed that under the 4 carbon source conditions, the accumulation of N2O showed a trend of first increasing, then decreasing, and finally remaining stable. The maximum accumulation of N2O were 1.59, 1.25, 5.43, 0.66 mg/L, and the maximum conversion rates were 1.61%, 1.36%, 5.44% and 0.67%, respectively. The final accumulation of N2O were 1.02, 0.67, 3.12, 0.49 mg/L, and the final conversion rates were 1.04%, 0.73%, 3.13% and 0.50%, respectively. The N2O release amount and conversion rate in descending order were glucose, sodium acetate, ethanol and sucrose. FNA inhibition, electronic competition of different denitrifying enzymes and differences in microbial community structure were factors affecting N2O release.
