A rapid startup shortcut nitrification method is researched with suppression factors,such as high temperature,high pH,low DO,etc.,in a SBR reactor,with anaerobic effluent(C/N 0.93-1.53) from a certain corn starch company wastewater treatment station.Targeting the already started up shortcut nitrification system,the stability and control strategy are studied further after cancelling the high pH and high temperature limiting factors.Results show that shortcut nitrification(NO_2~--N accumulation rate above80%)...
