The　discharge　of　nitrogen-containing　gaseous　pollutants　from　wastewater　treatment　plants　(WWTP)　has　caused　a　certain　threat　to　the　surrounding　environment　and　human　health,　which　has　attracted　wide　attention　in　recent　years.　This　study　investigated　the　release　characteristics　of　nitrogen-containing　pollutants　at　different　treatment　stages　in　WWTP　with　sequencing　batch　reactor　(SBR)　process,　including　nitrogen-containing　odorous　gases　(NH3　and　dimethylamine)　and　nitrogen-containing　greenhouse　gases　(N2O),　all　of　which　achieved　the　highest　release　in　the　aeration　stage,　with　emissions　of　35.2,　12.5　mg/(m2　&　sdot;d)　and　229.7　mg/L,　respectively.　Besides,　the　emission　factors　of　NH3　and　dimethylamine　were　calculated　for　0.0091　and　0.0026　g/m3,　and　the　carbon　emission　of　N2O　was　estimated　for　158.4　kg　of　CO2　per　day.　Furthermore,　the　pilot　experiment　of　SBR　showed　that　the　odorous　gas　decreased　first　and　then　increased　with　the　increase　of　aeration　intensity　and　sludge　concentration,　and　increased　with　the　increase　of　influent　chemical　oxygen　demand　(COD)　concentration.　This　study　provides　theoretical　and　data　support　for　the　emission　reduction　of　nitrogen-containing　pollutants　in　SBR　process　WWTP.
