文章摘要

Novel Mn–Fe–Mg- and Mn–Fe–Ce-loaded alumina (Mn–Fe–Mg/Al₂O₃ and Mn–Fe–Ce/Al₂O₃) were developed to catalytically ozonate reverse osmosis concentrates generated from petroleum refinery wastewaters (PRW-ROC). Highly dispersed 100–300-nm deposits of composite multivalent metal oxides of Mn (Mn²⁺, Mn³⁺, and Mn⁴⁺), Fe (Fe²⁺ and Fe³⁺) and Mg (Mg²⁺), or Ce (Ce⁴⁺) were achieved on Al₂O₃ supports. The developed Mn–Fe–Mg/Al₂O₃ and Mn–Fe–Ce/Al₂O₃ exhibited higher catalytic activity during the ozonation of PRW-ROC than Mn–Fe/Al₂O₃, Mn/Al₂O₃, Fe/Al₂O₃, and Al₂O₃. Chemical oxygen demand removal by Mn–Fe–Mg/Al₂O₃- or Mn– Fe–Ce/Al₂O₃-catalyzed ozonation increased by 23.9% and 23.2%, respectively, in comparison with single ozonation. Mn–Fe–Mg/Al₂O₃ and Mn–Fe–Ce/Al₂O₃ notably promoted OH generation and OH-mediated oxidation. This study demonstrated the potential use of composite metal oxide-loaded Al₂O₃ in advanced treatment of bio-recalcitrant wastewaters.
