Study of Phosphorus Removal Efficiency in Enhanced Biological Phosphorus Removal Process
An enhanced biological phosphorus removal (EBPR) system was developed in sequencing batch reactor (SBR) using acetate as the carbon source. The SBR was operated for over 2 months. Excellent phosphorus removal performance and stability were maintained in this system, where the phosphorous concentration in the effluent was below 0.6 mg/L. The Nile Blue staining was more specific than the Sudan black staining for the PHB. The DAPI staining and the Neisser staining for the poly-P were proper than other staining methods. SBR operation state after 2 months of start-up was stable.
