摘要：

To　investigate　the　effect　of　different　types　of　bioreators　on　N2O　production.　N2O　production　and　emission　in　nitrogen　removal　process　treating　real　domestic　wastewater　was　studied　utilizing　oxic-anoxic　SBR　system　and　intermittent　hybrid　biological　reactor　(HBR),　filling　rate　of　30%　and　operation　mode　of　instantaneous　water　inflow,　aeration　(360　min),　sedimentation　(40　min)　and　drainage　(20　min).　The　influence　of　different　bioreactors　on　N2O　production　in　nitrogen　removal　was　investigated　mainly.　In　the　SBR　system,　N2O　was　mainly　produced　in　nitrification.N2O　production　in　HBR　and　SBR　nitrification　was　0.76　mg/L　and　1.48　mg/L,　respectively.　Under　the　condition　of　the　SBR　bioreactor,　N2O　production　was　obviously　lower　than　that　in　the　HBR　bioreactor.
