In this study, hydrodynamic cavitationHydrodynamic cavitation (HC) and ultravioletUltraviolet (UV) techniques were employed to activate peroxydisulfatePeroxydisulfate (Na2S2O8) to degrade tetracycline (TCTetraCycline (TC)) model wastewater with an initial concentration of 30 mg/L and a volume of 15 L. The results demonstrate that over 95% of TCTetraCycline (TC) was degraded within 60 min at an inlet pressure of the Venturi of 0.35 MPa, a Na2S2O8 concentration of 1 mM, and a pH of 3. The synergistic index of the HC/UV/Na2S2O8 system was found to be as high as 7.5. Therefore, this work provides a highly feasible method for high-efficiency treatment of antibiotic wastewater.
