The temperature and functions of A~2/O process were closely related. Influence of temperature variation on nitrogen removal was studied. Results showed that COD removal rate would rise from 70% to 81.4% when temperature changed from 14.5℃ to 25℃ while COD removal rate was up to 85% when temperature changed from 25℃ to 34.3℃ ,. with removal rate stable and efficient. Under the temperature range of 25～30℃ which was the best for denitrification, the removal rate of TN was about 70% and nitrification could reach to 95%. Too high or too low temperature could inhibit function of nitrogen removal.
