摘要：

In　order　to　study　the　influencing　factors　during　the　conversion　process　of　Nitrous　oxide　(N2O),　batch　tests　were　conducted　with　the　sludge　treating　landfill　leachate　for　a　long　time.　In　this　study,　the　inhibitory　effect　of　free　nitrous　acid　(FNA)　concentration　on　N2O　reduction　and　accumulation　at　different　salinity　were　investigated.　The　results　show　that:　there　are　some　differences　of　the　minimum　inhibition　concentration　of　FNA　on　N2O　reduction　under　different　salinity,　which　gradually　reduce　as　the　increasing　of　salinity;　the　accumulation　of　N2O　increases　with　the　increase　of　salinity,　implying　that　N2O　production　is　bound　up　with　the　salinity;　the　accumulation　of　N2O　at　10,　20,　30,　35　and　40　g/L　salt　account　for　19.1%,　33.2%,　39.0%,　53.5%　and　56%　of　influent　total　nitrogen,　respectively;　the　acclimatization　of　sludge　can　increase　the　ability　to　resist　FNA　inhibition,　weaken　the　inhibition　of　FNA　on　N2O　reduction　and　thus　reduce　N2O　emission.
