Abstract The denitrification performance of simultaneous anammox and denitrification (SAD) granular sludge under different C/N was studied by batch test. The coupled system granular sludge was cultured in a UASB reactor with sufficient nitrogen,and it had high anammox activity and denitrification activity. Using glucose as carbon source, when the C/N were 1, 2, 4, there was no significant difference in the activity of ANAMMOX, and the denitrification activity increased gradually. The maximum rate of NO2--N degradation was 0.265, 0.345, and 0.453kgN/(kgVSS·d), respectively. When sodium acetate was used as the carbon source and the C/N ratios were 1, 2, and 4, respectively, neither of the ANAMMOX activity or the denitrification activity was affected. Under the same C/N, the activity of ANAMMOX with glucose as the carbon source was higher, while the denitrification activity with sodium acetate as the carbon source was higher.When C/N was 1, 2 and 4, the maximum degradation rate of NH4+-N with glucose as organic matter was 1.15, 1.19, 1.58times of sodium acetate respectively. The maximum degradation rate of NO2--N with sodium acetate as organic matter was 1.89, 1.48 and 1.15times of glucose, respectively. The mathematical simulation results of the experiment showed that the models can accurately predict the trend of nitrogen change during the experiment. There was no significant change in the ANAMMOX activity of the granular sludge in the coupled system when the C/N ratio was 1~4.
