文摘
- •
Effects of influent calcium content on the metabolic pathway of PAOs are explored.
- •
Evolution of glycogen and PHA confirm the change of PAO metabolic pathway.
- •
Ca-phosphate precipitation and Ca-bound polyP may affect the metabolism of PAOs.
- •
A modified PAO metabolism is proposed for Ca2+ containing wastewater treatment.
