Abstract The start-up and main factor of stable operation of partial nitrification in a configuration of two CSTR using domestic wastewater were studied. By adding (NH4)2SO4 to the domestic wastewater to improve the ammonia nitrogen concentration, and gradually controlling the two reactor DO to 1.5±0.12, 0.35±0.1 mg/L, more than 90.3% nitrite accumulation rate and 91.2% removal ammonia rate could be achieved after 45d. Under low ammonia domestic wastewater, through the comparison of the three groups of DO/ALR in the first reator, it showed that the effect of DO/ALR in 1.2~2.0mg O2/g N·d was the best. To decrease the concentration of ammonia nitrogen and increase the ratio of HRT to ALR, the maintenance of the DO/ALR ratio can also ensure the stability of the partial nitrification.
