Abstract Municipal sludge was enhanced pretreated with high-content metal and then pyrolyzed to form various sludge-derived biochar at low temperature. Pearson’s correlation analysis and characterization methods were employed to investigate the effects of high-content metal and pyrolysis temperature on phosphorus forms and phosphorus release from sludge-derived biochar. The results showed that the phosphorus release from sludge-derived biochar decreased with the increase of pyrolysis temperature, and a large amount of internal phosphorus was converted into ortho-P at 350℃. The enhanced pretreatment and pH had a greater effect on the phosphorus release and immobilization of metal element than pyrolysis temperature. Fe/Al-P and Ca-P competed for the coexistence of phosphorus, and Fe/Al-P was slightly dominant, while Ca-P had a significant effect on IP species. The ability of high-content metal to promote the conversion of OP to IP, inhibit phosphorus release, and hinder the conversion of HPO42- to H2PO4- was Fe>Al>Ca. The dominant phosphorus of calcium-based, and iron- and aluminum-based sludge-derived biochar were Ca-P and Fe/Al-P, respectively, of which Fe/Al-P was encapsulated by iron-aluminum oxides and was more difficult to release. Ca(H2PO4)2 was the primary form of phosphorus release. Fe-enhanced pretreatment has the greatest effect on the form and release of phosphorus in sludge-derived biochar, and Ca-enhanced pretreatment is conducive to the enhancement of bioavailable phosphorus, potentially providing new ideas for the resource utilization of municipal sludge-derived biochar.
