文摘
- •
Sludge lime stabilization supernatant (SLSS) was reused to treat reject water.
- •
High content of calcium and alkalinity in SLSS favors P removal from reject water.
- •
SLSS supplemented alkalinity and carbon for biological N removal from reject water.
- •
SLSS raised sludge flocs, and mitigated fouling of MBR for reject water treatment.
- •
Adding SLSS increased microbial abundance and biodiversity, and enriched nitrifiers.
