The objective of the study is to reconnoiter the degradation of anti-biotics from real veterinary pharmaceutical wastewater using a combined Electroflocculation and catalytic ozonation process by implying for the first time Fe-Zn loaded zeolite 5A as a catalyst in a hybrid reactor. Doxycycline, Tylosin Tartrate, and Timlicosin Phosphate were identified in pharmaceutical wastewater and were selected as target antibiotics. BOD, COD, and turbidity are the major pollutant indicators in any type of wastewater; therefore, these were selected and influence by various parameters such as ozone flow (0.8–1.55 mg/min), catalyst dose (5–15 g/L), and DC volts (5–15 V) were studied. Moreover, degradation efficiencies of the Doxycycline, Tylosin Tartrate, and Timlicosin Phosphate were compared with single ozonation, Electroflocculation (EF), catalytic ozonation, and combined process (EF + Fe-Zn-zeolite 5A/O₃). The results revealed that combined process (EF + Fe-Zn-zeolite 5A/O₃) has highest elimination efficiency i.e., 41 %, 77 % and 79 % of the BOD, COD and Turbidity respectively at optimum parameters values of (DC volts = 10 V; ozone flow = 1.1 mg/min and catalyst dose = 10 g/L). Moreover, degradation of anti-biotics was also the highest in the case of the EF + Fe-Zn-zeolite 5A/O₃ process and was 55 %, 57 %, and 99 % for Timlisoin Phosphate, Doxycycline, and Tylosin tartrate respectively in challenging wastewater. Based on the results of experimental work, it is established that the proposed combined process (EF + Fe-Zn-zeolite 5A/O₃) is appropriate for the effective treatment of pharmaceutical wastewater.

该研究的目的是通过首次将载有 Fe-Zn 的 5A 沸石作为混合反应器中的催化剂，使用电絮凝和催化臭氧化相结合的工艺来侦察真正的兽药废水中抗生素的降解。在制药废水中鉴定出强力霉素、酒石酸泰乐菌素和磷酸替米考星，并被选为目标抗生素。BOD、COD和浊度是任何类型废水的主要污染物指标；因此，这些被选择并受到各种参数的影响，例如臭氧流量 (0.8–1.55 mg/min)、催化剂剂量 (5–15 g/L) 和直流电压 (5–15 V)。此外，将强力霉素、酒石酸泰乐菌素和磷酸替米考星的降解效率与单一臭氧化、电絮凝 (EF)、催化臭氧化、₃）。结果表明，联合工艺（EF + Fe-Zn-沸石5A/O ₃）具有最高的去除效率，即在最佳参数值（DC volts = 10 V；臭氧流量 = 1.1 mg/min 和催化剂剂量 = 10 g/L)。此外，抗生素的降解在 EF + Fe-Zn-沸石 5A/O ₃工艺的情况下也是最高的，磷酸替米松素、强力霉素和酒石酸泰乐菌素的降解率分别为 55%、57% 和 99%。具有挑战性的废水。根据实验工作结果，确定了所提出的联合工艺（EF + Fe-Zn-沸石5A/O ₃）适用于制药废水的有效处理。
