摘要

Optimizing anoxic biological phosphorus removal in the anaerobic-anoxic sequencing batch reactor (A_2SBR) was observed to depend greatly on three parameters: the amount of added nitrate, the sludge retention time (SRT) and the phosphorus/carbon feeding ratio (P/C, wt/wt). The concentration of 120 mg N-NO_3 l~-1 in the anoxic medium corresponding to 800 mg COD l~`-1 acetic acid and 60 mg P-PO_4 l~-1 in the synthetic wastewater, the SRT of 15 days and the P/C feeding ratio of 20/100 were determined as optimal for complete phosphorus removal in the A_2 SBR.
