This　paper　reported　a　study　on　controlling　alkalinity　method　in　partial　nitrification　to　produce　the　correct　influent　for　anaerobic　ammonium　oxidation　(anammox)　process.　The　start-up　of　the　partial　nitrification　realized　within　8　days　at　a　high　temperature　(35±0.1　°C)　and　free　ammonia　(17.7　mg/L).　And　the　bacteria　were　almost　coccus,　so　the　Ammonium-Oxidizing　Bacteria　(AOB)　affiliated　to　Nitrosococcus　in　a　preliminary　estimate.　When　the　molar　ratio　of　bicarbonate　to　ammonium　was　1:1,　the　effluent　of　the　Sequencing　Batch　Reactor　(SBR)　could　be　effectively　suitable　for　a　subsequent　anammox　process　with　the　molar　ratio　of　ammonium　to　nitrite　of　1:1.　©　2014　Taylor　&　Francis　Group,　London.
