Abstract：

SBR　reactors　were　used　to　investigate　the　N2O　emission　in　shortcut　nitrification　and　simultaneous　nitrification　and　denitrification　(SND).　Shortcut　nitrification　with　nitrosation　rate　above　90%　was　realized　by　real-time　control　strategy.　The　N2O　emission　and　variation　of　nitrosation　rate　were　investigated　under　4　DO　levels　(0.5,　1.0,　1.5,　2.0　mg/L).　The　results　turned　out　that　the　optimal　DO　to　maintain　high　nitrosation　rate　and　minimum　N2O　emission　was　1.5　mg/L　and　the　N2O　emission　was　0.06　g　per　ammonium　removed.　The　SBR　filled　with　carbon　fiber　performed　under　low　DO　and　pulse　feeding.　The　SND　rate　was　over　79%　during　the　experiment.　The　N2O　emission　was　studied　under　DO　0.2,　0.4,　1.0　and　1.5　mg/L.　It　turned　out　that　the　optimal　DO　was　1.0　mg/L　and　the　N2O　emission　was　0.021g　per　ammonium　removed.　Compared　to　the　shortcut　nitrification,　the　N2O　emission　of　SND　was　1/3　of　the　short-cut　nitrification　under　optimal　DO.
