Abstract

Nitrous oxide （N2O） is one kind of potent greenhouse gas which can destroy ozone layer and lead to acid rain. Furthermore, nitrous oxide is quite easy to be converted into the secondary particle pollutants which can aggravate haze in certain weather conditions. Effective control of N2O emission has become imminent and the researches on N2O reduction have been get more and more attention. Related researches indicate that the process of wastewater biological denitrification is one of main artificial sources of N2O emission. And with the popularity of wastewater biological denitrification process, the emission quantity and harmness of N2O increases gradually. In this work, the mechanism of N2O generation in wastewater nitrification and denitrification process is revealed and the various influence factors to N2O emission is summarized. And then, the present reduction control techniques of N2O is analyzed in detail. On these basises, the future research directions of N2O reduction control is prospected.
