A　two-sludge　system　integrated　anaerobic/anoxic　process　with　biological　aerated　filter　(AA-BAF)　was　used　to　treat　real　domestic　wastewater.　To　evaluate　nutrients　removal　performance　and　operational　stability,　AA-BAF　system　was　operated　at　room　temperature　for　50　d　continuously.　The　results　show　that　as　high　as　87%　COD,　99%　NH4+-N　and　79%　TN　are　removed　successfully　throughout　the　experiment.　While　the　obvious　deterioration　of　phosphate　removal　is　observed,　decreasing　from　approximately　80%　(1-30　d)　to　less　than　40%.　All　soluble　influent　COD　is　completely　consumed　in　AA　reactor　for　nutrients　removal.　NO3--N　in　nitrified　liquor　from　BAF　recycled　to　the　anoxic　zone　is　wholly　removed.　The　mean　effluent　COD　and　NO3--N　are　as　low　as　50　mg/L　and　0.3　mg/L　respectively.　Moreover,　when　NO3--N　concentrations　in　AA　effluent　is　less　than　0.3　mg/L,　the　effluent　PO43--P　concentration　is　above　the　limit　value　of　0.5　mg/L.　Totally　through　denitrifying　phosphate　removal　pathway,　AA-BAF　continuous　denitrifying　phosphorous　removal　system　treating　domestic　wastewater　can　not　ensure　long　term　stable　operation　and　efficient　phosphate　removal.　©,　2014,　Central　South　University　of　Technology.　All　right　reserved.
