Effective and sustainable removal of low-concentration phosphate is imperative but challenging for advanced wastewater treatment. Additionally, an eco-friendly cost-effective treatment reuse waste activated sludge critical. To address these problems, sludge-biochar-based adsorbents were developed by pyrolyzing then functionalizing with Ca–La layered double hydroxide (LDH). The LDH's structure adsorption characteristics optimized substituting the intercalated ion CO32– NO3–. A maximal phosphorus capacity 78.24 mg P/g was achieved. Adsorption kinetics showed that 0.2 g/L functionalized biochar effectively lowered PO43––P concentration from 7.0 to <0.02 mg/L within 2 h. desirable (7 mg/L) selectivity toward coexisting anions such as sulfate (120 carbonate (250 mg/L), resulting in barely impacted capabilities.
