The biogas residue (BR) from the anaerobic digestion of sludge poses a threat to environment due presence toxic and hazardous substances. Furthermore, emerging contaminants, such as bisphenol A (BPA), are widespread in domestic industrial wastewater, requiring efficient sustainable treatment technologies. In this study, BR-based biochar was pyrolyzed urea-modified BR employed catalyst activate peroxymonosulfate (PMS) for BPA degradation. With at 750 °C catalyst, 20 mg/L completely removed. Free radical detection confirmed that hydroxyl (•OH) sulfate (•SO4−) generation decreased with increase reuse times. X-ray photoelectron spectra showed deactivation mainly resulted -COOH C-OH group loss, which acted active sites generating •OH •SO4−, HCl or NaOH regeneration catalysts could recover oxygen-containing functional groups, boosting removal 54.7% 91.5% 100%, respectively. Thermal only enlarge catalyst’s specific surface area (SSA) adsorption capacity, but might not restore free capability. This research offered theoretical basis utilization provided reference reusing wastewater treatment.

Global industrialization has intensified the emission of emerging contaminants (ECs), posing a serious threat to environment and human health. Persulfate-based advanced oxidation processes (PS-AOPs) have become research hotspot due their efficient degradation capability environmentally friendly features; carbon-based materials are ideal catalysts for activating persulfate (PS) tunable electronic structure, abundant active sites, low cost. This study summarizes application (graphene, single-atom (SACs), etc.) in PS-AOPs, provides insights into mechanisms radicals (e.g., sulfate radical (SO4−·), hydroxyl (·OH)) non-radicals 1O2(singlet oxygen), electron transfer). The removal efficacy antibiotics, phenols, dyes was compared, key pathways were elucidated. In addition, activation PS can be accelerated, catalytic efficiency improved by synergizing with ancillary technologies light, electricity). Despite great potential catalysts, large-scale is limited complexity catalyst preparation process lack selectivity complex water qualities. Future studies accelerate practical PS-AOPs wastewater treatment through precise design SACs construction multi-mechanism synergistic systems.
