The　CANON　(completely　autotropic　nitrogen　removal　over　nitrite)　process　has　been　received　abroad　attention　in　wastewater　treatment　recent　years.　In　the　study,　a　Sequencing　Batch　Reactor　(SBR)　was　used　to　treat　domestic　wastewater　using　intermittent　aeration　with　low　dissolved　oxygen　(DO).　After　inoculating　partial　nitrification　sludge　and　anammox　sludge,　the　reactor　was　started-up　successfully　under　appropriate　temperature　and　sludge　concentration.　By　using　intermittent　aeration　with　low　DO,　the　system　achieved　the　inhibition　and　elimination　of　nitrite-oxidizing　bacteria　(NOB).　The　harmonious　effect　of　partial　nitrification　and　anammox　made　the　system　stable.　In　the　stable　phase,　the　reactor　had　a　good　performance　on　the　contaminant　removal.　With　the　influent　concentrations　of　total　nitrogen　and　ammonia　of　63.9　mg·L-1　and　62.7　mg·L-1,　the　effluent　of　them　were　12.3　mg·L-1　and　7.6　mg·L-1　and　the　removal　rates　of　them　were　77.8%　and　86.7%,　respectively,　with　the　volume　loading　of　total　nitrogen　removal　of　0.16　kg　N·(m3·d)　-1.　Thus,　the　experiment　provided　references　for　the　application　of　the　operation　mode　in　autotrophic　nitrogen　removal　of　wastewater.　©　All　Right　Reserved.
