Summary: A new magnetite-contained biochar was prepared using iron-rich Fenton sludge as raw material, with the transformation of amorphous iron oxides into magnetite at 400 degrees C of pyrolysis and preservation of redox quinone/hydroquinone moieties of biochar. This magnetic biochar exhibited high capacitance and excellent conductivity, leading to significantly enhanced methane production when supplemented into anaerobic digestion system, offering a new approach to recycle hazardous Fenton sludge.

Summary: This study demonstrates the feasibility of achieving energy recovery from phosphate-containing domestic sewage using an efficient anaerobic reactor with ZVI addition. The inhibitory effects of phosphate on ZVI dissolution are weakened by the use of ZVI@carbon composites, which promote methane production. The interaction between Fe2+ ions and phosphate concentrations and the surface passivation layer formation on ZVI are key factors influencing the effectiveness of ZVI in the presence of phosphate.
