摘要：

In　order　to　investigate　the　nitrogen　removal　performance　of　sequencing　batch　reactor　(SBR)　process　treating　the　wastewater　with　high　COD/NH+4-N　ratio,　a　post-denitrification　SBR　was　proposed　to　treat　the　immature　landfill　leachate.　No　extra　carbon　source　was　added　at　the　beginning　of　anoxic　stage,　while　real-time　control　was　used　during　the　aerobic　stage　to　indicate　the　completion　of　nitrification.　The　results　showed　that　outstanding　nitrogen　performance　was　obtained　in　the　experimental　period.　The　COD　removal　rate　of　more　than　89%　and　97%　for　TN　were　achieved　under　the　influent　COD　and　TN　of　2117.1　mg·L-1　and　305.6　mg·L-1,　respectively,　which　realized　the　effluent　TN　concentration　below　10　mg·L-1.　PHB　storing　in　the　anaerobic　and　feast　period　of　anoxic　stage　could　be　used　as　the　internal　carbon　source　for　denitrification,　which　led　to　the　average　endogenous　denitrification　rate　of　1.40　mgN·h-1·gVSS-1.　Thus,　advanced　nitrogen　removal　was　realized　without　extra　carbon　source　addition.　©　2012　IEEE.
