Better denitrification efficiency could be obtained with adding amylo and the removal ratios of ammonia nitrogen were at least 93%. The removal ratio of TN increased gradually with the increasing of C/N ratio. When C/N ratio was 10, the best removal ratio of TN could reach 80.81%. But when C/N ratio added on 12, the ratio removal of TN was not increased only keeping about 75%.
