| 英文摘要 | Phosphorus is a non-renewable resource that guarantees food production, while excessive phosphorus discharge leads to water eutrophication. Phosphorus removal/recovery could help improve water quality and ensure food security. In this contribution, silica-stabilized amorphous calcium carbonates (Si-ACC) were prepared and used to remove/recover phosphate in sludge and domestic sewage. The mechanisms were investigated via kinetic and isothermal adsorption studies and XRD, TEM, Raman, and FT-IR characterization. The results showed that the homogeneously distributed silica successfully inhibited ACC transformation and helped Si-ACC keep the amorphous feature within 680 d. During phosphorus adsorption, Si-ACC quickly transformed into calcite within 5 min and reacted with phosphorus to generate polycrystalline hydroxylapatite within 60 min. The recovered product possessed a maximum specific surface area (SSA) of 209 m2/g and available phosphorus content of 18.0 %, suggesting that Si-ACC was a promising phosphorus recovery material and the recovered product could be a potential phosphate fertilizer. |
