The experimental results showed that only under condition that each ecological factor was maintained relative steady , simultaneous nitrification and denitrification might proceed smoothly. When DO , C/ N and p H of feed water was 1mg/ L , 30 and 7. 2 , the removal rate of COD , NH+ , and TN were 96 % , 95 % and 92 % 4 respectively.
