摘　　要：污水处理过程中会产生大量的温室气体,其中包括一氧化二氮(N_(2)O),而N_(2)O的增加会对气候变化和生态环境产生显著影响。本文综述了在硝化作用、反硝化作用、同步硝化反硝化、反硝化除磷、好氧颗粒污泥和厌氧氨氧化过程中产生N_(2)O的机理。同时,总结了影响N_(2)O释放的因素以及减少N_(2)O排放的方法,并对未来污水处理中N_(2)O减排的研究方向进行了展望。During the sewage treatment process,a large amount of greenhouse gases are generated,including nitrous oxide(N_(2)O),and the increase of N_(2)O will have a significant impact on climate change and the ecological environment.This article summarizes the mechanisms of N_(2)O production in nitrification,denitrification,simultaneous nitrification denitrification,denitrifying phosphorus removal,aerobic granular sludge,and anaerobic ammonia oxidation processes.At the same time,factors affecting N_(2)O release and methods for reducing N_(2)O emissions were summarized,and future research directions for N_(2)O emission reduction in wastewater treatment were discussed.
