In　this　study,　partial　nitrification　and　post　endogenous　denitrification　(PED)　were　combined　with　enhancing　bacterial　phosphorus　removal　(EBPR)　in　an　anaerobic/aerobic/anoxic　operated　sequencing　batch　reactor　(SBR)　for　deep-level　nutrient　removal　from　low　carbon/nitrogen　(C/N,　chemical　oxygen　demand　(COD)/total　nitrogen　(TN))　domestic　wastewater.　At　anaerobic　stage,　abundant　organic　matters　(96.6%　of　COD　consumption)　in　raw　wastewater　were　stored　as　poly-hydroxyalkanoates　(PHAs)　by　phosphorus　and　glycogen　accumulating　organisms　with　enhanced　activities,　which　provided　sufficient　intracellular　carbons　for　subsequent　aerobic　phosphorus　uptake　and　anoxic　PED.　By　controlling　suitable　aeration　rate　and　duration,　high　nitrite　accumulation　rate　(97.2%)　was　obtained　at　aerobic　stage,　which　saved　intracellular　carbons　consumption　of　PED.　Moreover,　the　subsequent　utilization　of　glycogen　after　PHAs　via　PED　ensured　the　deep-level　TN　removal　(94.9%)　without　external　carbon　addition.　After　160-day　operation,　the　average　effluent　PO43--P　and　TN　concentrations　were　0.4　and　3.0　mg/L,　respectively,　at　C/N　of　3.1.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
