Abstract :
The impact of organic matter concentration on nitrification was studied in shortcut nitrification SBR. The results showed that the competition of aerobic bacteria had been enhanced and degradation rate of ammonia had been reduced in the system with the increasing of COD concentration and the loading of sludge. Denitrification in the system was apparent, removal rate of total nitrogen was increased gradually and the removal of TN was mainly in shortcut denitrification. The proportion of nitrite in the nitrogen oxides had been increased, because the removal rate of nitrate was higher than that of nitrite. Higher concentration of organic matter did not apparently affect AOB and NOB.
