Abstract

In this examination we have experimented the effect of ammonia concentration on shortcut nitrification and denitrification in a moving bed biofilm reactor (MBBR). The results show that, when the influent ammonia concentration slowly increased to 200 mg/L, the ammonia removal rate and the nitrite accumulation rate were respectively 92.7% and 84.2%, which were better than that of other influent ammonia concentration. And when the influent ammonia concentration was 200 mg/L, the average TN removal rate was also better than other influent ammonia concentration, which was 56.0%. The TN removal rate increased first and then decreased with the influent ammonia concentration increase.
