Abstract :
COD,TN and TP removal efficiency was studied in different C/N in the system by changing the dosage of CH3COONa. The best results obtained by experiment is that when the C/N is between 4 and 6 .The average COD effluent concentration is 40.08 mg/L, the removal rate is 87.5%;the average TN effluent concentration is 9.32 mg/L, the removal rate is 83.91%; the TP average effluent concentration is 1.02 mg/L, the removal rate is 88.1%. Too high or too low C/N is not conducive to removal rate of system.
