To　obtain　economically　sustainable　wastewater　treatment,　advanced　nitrogen　removal　from　municipal　wastewater　and　the　feasibility　of　achieving　and　stabilizing　short-cut　nitrification　and　denitrification　were　investigated　in　a　pilot-plant　sequencing　batch　reactor　(SBR)　with　a　working　volume　of　54　m(3).　Advanced　nitrogen　removal,　from　summer　to　winter,　with　effluent　TN　lower　than　3　mg/L　and　nitrogen　removal　efficiency　above　98%　was　successfully　achieved　in　pulsed-feed　SBR.　Through　long-term　application　of　process　control　in　pulsed-feed　SBR,　nitrite　accumulation　reached　above　95%　at　normal　temperature　of　25　degrees　C.　Even　in　winter,　at　the　lowest　temperature　of　13　degrees　C,　nitrite　was　still　the　end　production　of　nitrification　and　nitrite　accumulation　was　higher　than　90%.　On　the　basis　of　achieving　advanced　nitrogen　removal,　short-cut　nitrification　and　denitrification　was　also　successfully　achieved.　Compare　to　the　pulse-feed　SBR　with　fixed　time　control,　the　dosage　of　carbon　source　and　energy　consumption　in　pulsed-feed　SBR　with　process　control　were　saved　about　30%　and　15%　respectively.　In　pulsed-feed　SBR　with　process　control,　nitrogen　removal　efficiency　was　greatly　improved.　Moreover,　consumption　of　power　and　carbon　source　was　further　saved.
