To achieve efficient filtration and enhance the degradation of antibiotics in water, a CoFe2O4-modified flat-sheet ceramic membrane was prepared using the impregnation-sintering method. The performance of this ceramic membrane activated by peroxymonosulfate (PMS) for the removal of florfenicol (FLO) and other antibiotics was investigated under dead-end filtration mode. The results indicated that at a pH value of 6 and a PMS dosage of 0.5mmol/L, the removal efficiency of FLO (10mg/L) was achieved at 88% within 30minutes. Furthermore, the system exhibited excellent resistance to interference from coexisting species such as Cl-, NO3-, HCO3- and humic acid. After 7 cycles of FLO degradation using the CoFe2O4 ceramic membrane/PMS system, the removal rate of FLO remained high at 84%. Mechanistic studies revealed that HO·, SO4·-, O2·-, 1O2 were identified as the primary reactive species responsible for the catalytic degradation. Treatment results of actual aquaculture wastewater showed that the removal efficiencies for COD and turbidity were 65.4% and 99.3%, respectively. Simultaneously, the removal rates for eight typical antibiotics present in the wastewater exceeded 80%, highlighting its significant potential for practical application.
