摘要 当今社会,抗生素被广泛应用在临床医学上,能够对抗人体内的致病菌,治疗细菌等微生物感染导致的疾病,有的抗生素能起到免疫抑制作用。但在广泛使用抗生素的同时却不对抗生素废水进行处理,导致抗生素废水流入河道,河水遭到污染。光催化技术作为处理污染的一种新兴技术,具有绿色环保、成本低的特点,同时也可以降解水中的抗生素。本文使用化学共沉淀法和液相还原法分别制备出CoFe_(2)O_(4)单体和Cu_(2)O/CoFe_(2)O_(4)的复合物。将Cu_(2)O/CoFe_(2)O_(4)的复合物作为催化剂降解四环素废水。实验中,通过改变四环素废水浓度、四环素的酸碱度、PMS的用量和催化剂的用量,运用单因素试验法控制变量,从而探索出降解四环素废水的最佳优化条件。 In today's society,antibiotics are widely used in clinical medicine,which can fight against pathogenic bacteria in the human body and treat diseases caused by microbial infections such as bacteria.Some antibiotics can play an immunosuppressive role.However,while antibiotics are widely used,antibiotic wastewater is not treated,resulting in antibiotic wastewater flowing into the river and river water being polluted.As a new technology for pollution treatment,photocatalysis technology has the characteristics of green environmental protection and low cost.At the same time,it can also degrade antibiotics in water.In this paper,CoFe_(2)O_(4) monomer and Cu_(2)O/CoFe_(2)O_(4) composite were prepared by chemical coprecipitation and liquid phase reduction,respectively.The compound of Cu_(2)O/CoFe_(2)O_(4) was used as catalyst to degrade tetracycline wastewater.In the experiment,by changing the concentration of tetracycline wastewater,the pH of tetracycline,the amount of PMS and the amount of catalyst,the single factor test method was used to control the variables,so as to explore the best optimization conditions for the degradation of tetracycline wastewater.
