In　this　study,　a　novel　laboratory-scale　synchronous　enhanced　biological　phosphorus　removal　and　semi-nitritation　(termed　as　EBPR-SN)　combined　with　anammox　process　was　put　forward　for　achieving　nutrient　elimination　from　municipal　wastewater　at　27　celcius.　This　process　consisted　of　two　10　L　sequencing　batch　reactors　(SBRs),　i.e.　EBPR-SN　SBR　followed　by　Anammox　SBR.　The　EBPR-SN　SBR　was　operated　for　400　days　with　five　periods　and　the　Anammox　SBR　was　operated　starting　on　period　IV.　Eventually,　for　treating　municipal　wastewater　containing　low　chemical　oxygen　demand/nitrogen　(COD/N)　of　3.2　(mg/mg),　the　EBPR-SN　plus　Anammox　system　performed　advanced　total　inorganic　nitrogen　(TIN)　and　P　removal,　with　TIN　and　P　removal　efficiencies　of　81.4%　and　94.3%,　respectively.　Further　analysis　suggested　that　the　contributions　of　simultaneous　partial　nitrification　denitrification,　denitrification,　and　anammox　to　TIN　removal　were　15.0%,　45.0%,　and　40.0%,　respectively.　The　enriched　phosphorus-accumulating　organisms　(PAOs)　in　the　EBPR-SN　SBR　facilitated　P　removal.　Besides,　the　EBPR-SN　SBR　achieved　P　removal　and　provided　stable　anammox　substrates,　suggesting　a　short　sludge　retention　time　(SRT　12　d)　could　achieve　synergy　between　ammonia-oxidizing　bacteria　and　PAOs.　These　results　provided　an　alternative　process　for　treating　municipal　wastewater　with　limited　organics.　[GRAPHICS]　.
