Kinetics analysis of anaerobic/anoxic SBR denitrifying phosphorus removal system

摘要

Kinetic equations of soluble components are analyzed in an anaerobic/ anoxic sequencing batch reactor (A/A SBR) enriched with denitrifying phosphorus removing bacteria (DPB) sludge.Mathematical model is established for denitrifying phosphorus removal process.The model is based on the simplification of the metabolic model for biological phosphorus removal by DPB.A proper set of kinetic parameters was calculated from the data obtained in the batch tests.The model was subsequently applied for the simulation of cycle behavior of soluble components in the A/A SBR.The results of the simulation indicated that the model can predict the concentration of each component for denitrifying phosphorus removal successfully.
