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%.

投加淀粉调整C/N比，系统能取得良好的脱氮效果，氨氮的去除率均在93%以上，随着C/N比的增加，TN的去除率也逐渐的增大，当C/N为10时，TN最高去除率能达到80.81%，但当C/N增大到12时，TN的去除率不再增大，只是稳定在75%左右。
