A　system　which　combined　ASBR　with　pulsed　SBR　(PSBR)　was　introduced　to　enhance　COD　and　nitrogen　removal　from　the　real　landfill　leachate.　ASBR　was　used　to　degrade　the　organics　from　raw　leachate　mainly.　Three　equal　feeds　mode　was　applied　in　PSBR　operation.　The　results　obtained　from　the　joint　operation　period　(157　days)　show　that　the　COD　removal　rate　of　ASBR　was　83-88%　under　the　specific　loading　rate　of　0.43-0.62　gCOD　gVSS(-1)　day(-1).　PSBR＇s　operation　can　be　divided　into　four　phases　according　to　the　different　influent　NH4+-N　which　increased　to　800-1000　mg　L-1　finally,　and　total　nitrogen　(TN)　removal　rate　of　more　than　90%　with　the　effluent　TN　of　less　than　40　mg　L-1　was　obtained.　PHB　and　glycogen　can　act　as　electron　donor　for　endogenous　denitritation　orderly　with　the　hypothetical　function　from　DNGAOs.　Consequently,　the　system　achieved　COD　and　TN　removal　rate　of　89.61-96.73%　and　97.03-98.87%,　respectively,　without　any　extra　carbon　source　addition.　(C)　2012　Elsevier　Ltd.　All　rights　reserved.
