Mechanism and regulation of N2O production and elimination in Anammox-DAMO system under the influence of temperature
The Anammox-DAMO system was used to investigate the effects of temperature on the system performance and N2O production and consumption.The enzymatic kinetics model of the process was established.The results showed that the system performance deteriorated significantly and more N2O was accumulated under the high temperature stress(40℃).The abundance of Acidovorax and Thauera genera decreased significantly under high temperature conditions,while the abundance of Bacillus genera increased.Inhibition of N2O reductase activity was the main cause of the increase in N2O emissions.The enzyme kinetics results indicated that N2O emission reduction can be maximized at 35℃.
