Abstract. Dissolved Oxygen(DO) is one of the primary influencing factors in the system of short-cut nitrification, In order to find the appropriate DO concentration, in a stable SBR system, to simulate the sewage to treatment target, raction and stability of operation results of nitrification system was studied by changing the DO concentration. Experiments showed when the DO concentration <1mg/L time, the higher the DO concentration, the faster the rate of ammonia oxidation. To achieve the stable operation, the DO concentration must be strictly controlled in the reactor, too low or too high would undermine the stability of the system , the optimal range of DO concentration was0.5 ~ 0.7mg/L.
