EVALUATION OF ACTIVATED SLUDGE MODEL No.2 AT HIGH PHOSPHORUS CONCENTRATIONS

摘要

This paper presents laboratory scale experimentation carried out to study enhanced biological phosphorus removal at high phosphorus concentrations in a sequencing batch reactor. Four series of data obtained in a sequencing batch reactor are examined in light of the Activated Sludge Model No.2. This model was calibrated using data form the first and second series working at low phosphorus concentrations. The Activated Sludge Model No. 2 successfully characterised the enhanced biological phosphorous removal performance of the sequencing batch reactor at low phosphorus concentrations.
