The process of ANAMMOX adopting nitrosification was studied at the normal temperature and the influence of a
higher pH value on the nitrosification performance was investigated． The experiments used actual domestic wastewater and a
stable operating SBR( sequencing batch reactor of activated sludge process) and controlled temperature，pH to investigate
variation condition of NH+
4 －N and NO －
2 －N． The nitrosification reaction was achieved successfully and accumulation rate of
NO －
2 －N was 93. 45% when the temperature was at 28 ℃． The effluent NH +
4 －N/NO －
2 －N was at 1∶ 1. 3 when the temperature
was around 26 ℃，which is suitable for providing stable conditions for anammox． The stable nitrosification can be realized at a
higher pH by neutralizating H + and inhibiting NOB activity by FA and FNA．
