文摘
- •
Potential recovery of P was studied by XRD and DSC-TGA by sewage sludge incineration treatment.
- •
Phosphorus enriched in SSA and its distribution in fly ash was studied.
- •
High temperatures and CaO promote the transformation from NAIP to AP.
- •
AP is more stable than NAIP in high temperatures.
- •
The reactions between NAIP and CaO at different temperatures were determined.
