Biological phosphorus removal with granular sludge in SBR

摘要：

The formation and performance of granular sludge seeded with flocculating sludge was studied in a 4L sequencing batch reactor (SBR) treating a synthetic wastewater with sodium acetate as carbon source. By gradually reducing the settle time from 30 to 10 min, granule sludge was formed on day 20.The granules had a specific gravity of 1.0439, diameters of 0.5-2mm, and sludge volume index (SVI) of less than 50mL/g. Phosphorus removal granular sludge had good phosphorus removal characteristics. The efficiency of phosphorus removal was over 90％. The max. specific phosphorus release rate (SRPR) and the max. specific phosphorus uptake rate (SUPR) was 62.65 mg/(gVSS·h) and 51.76 mg/(gVSS·h), respectively. And the sludge phosphorus content (TP/SS) was 6.5％.
