文摘
- •
Sludge was treated with combined peracetic acid and chemical flocculation.
- •
Sludge particles were effectively solubilized with PAA oxidation.
- •
Protein-like substances were degraded into small molecules after PAA oxidation.
- •
Degradation of protein-like substances was favored at acid conditions.
- •
PACl performed better in re-flocculation than ferric ions.
