The traditional treatment of antibiotics confronts high energy consumption but low removal efficiency. In this study, a photo-Fenton ceramic membrane (PF-CM) was prepared by an innovative and facile approach of spray printing method with nano hematite (α-Fe₂O₃) for the removal of tetracycline hydrochloride (TC) as a model antibiotic. The SEM, TEM, XPS, and UV–Vis DRS were used to characterize the PF catalyst of α-Fe₂O₃. The as-prepared α-Fe₂O₃ was loaded to a flat ceramic membrane (CM) by a spray printing and low-temperature sintering method to form a photo-Fenton reactive membrane (α-Fe₂O₃-CM). A new α-Fe₂O₃-CM fixed bed water treatment system with visible LED light was fabricated for the removal of TC by comprehensive consideration of degradation rate and permeates flux. The reusability and stability of the α-Fe₂O₃-CM were also investigated. To reveal the reactive radicals involved in the PF-CM process for a deeper insight into the degradation mechanisms, quenching experiments and EPR analysis were performed. The SEM/EDS images indicated that the α-Fe₂O₃ was loaded tightly onto the α-Fe₂O₃-CM, and pure water permeates flux of the α-Fe₂O₃-CM could reach as high as 55.8 kg/(m²·h·kPa). The α-Fe₂O₃-CM fixed-bed treatment system is suited for TC treatment, and the removal efficiency could reach 82% even when the TC concentration is as low as 20 mg/L. Moreover, α-Fe₂O₃-CM could retain long-term stability and exhibit a self-cleaning function in antibiotic wastewater treatment for five cycles, which was further confirmed by SEM/EDS images and iron dissolution experiments. The quenching experiments and EPR analysis revealed that reactive radicals involved in the PF-CM process were h⁺, ·O₂⁻, and, ·OH responsible for TC degradation. This research also provides a utilization proposal for scale-up α-Fe₂O₃-CM for water and wastewater treatment.
