Catalytic ozonation performance and mechanisms of Cu-Co/γ-Al2O3 to achieve antibiotics and ammonia simultaneously removal in aquaculture wastewater Process Saf. Environ. Prot. (IF 6.9) Pub Date : 2024-08-29 Shupo Liu, Zixiang He, Xiaobin Liao, Xinyue Liu, Menglan Gao, Huayu Zhang, Jing Zou, Zhenming Zhou, Baoling Yuan, Zhimin Yang
Antibiotics and ammonia are generally co-existed in aquaculture tailwater; moreover, ammonia would also be produced from during ozonation, and should be simultaneously removed before discharge or reuse. In this study, catalyst Cu-Co/γ-AlO was screened from a variety of metal oxides and applied in catalytic ozonation of three kinds of antibiotics and NH-N. Factors that affected their removal, including
