Abstract：Using Sequencing Batch Reactor (SBR) treating domestic wastewater, quick start of partial nitrification was carried out through the mode of alternating anoxic/oxic. Time of achieved partial nitrification, treatment efficiency and ammonia utilization rate were investigated in different ratio of anoxic/oxic time. The results showed that the ratio of anoxic/oxic time was 1:1and 2:1, while two systems nitrite accumulation rate raised to 90% after 31days and 55days respectively, the state of partial nitrification was stable. Besides, ammonia removal efficiency was attained above 95% and the COD effluent concentration was less than 50mg/L. The total nitrogen removal was enhanced about 20%, and pollutants removal efficiency was increased. Form the complete nitrification to the partial nitrification, ammonia utilization rate increased 67.5% and 89.8% respectively, at the same time, efficiency of the partial nitrification was improved. Meanwhile, sludge had significantly better settling performance, sludge volume index was stable at 60~80mL/g.
