Abstract

In this study, the aim was to investigate the various carbon sources, included methanol, glucose and ethanol, to estimate the removal efficiency of nitrogen and phosphorus in anaerobic-anoxic-oxic (A2/O) process by laboratory experiments. Total nitrogen (TN) and total phosphorus (TP) removal efficiencies were 78.23% and 78.18%. The removal efficiencies of TN, NH3-N and TP were 82.36%, 96.67% and 92.18%, respectively. The effluent concentrations were 11.43mg/L,4.1mg/L and 0.45mg/L, respectively, which reached the type A standard GB18918-2002 level.
