摘　　要：由于抗生素的大量生产和过度使用,近年来在全球水体和土壤中被频繁检测到,这不仅对生态系统造成了危害,同时威胁着人类的健康。化学氧化技术可将抗生素分解成无毒或毒性较低的小分子物质,从而降低抗菌活性,并提高其可生化性和矿化率。针对水中抗生素的化学氧化处理,着重综述臭氧直接氧化及臭氧高级氧化、氯氧化、芬顿及类芬顿法这3类化学氧化技术,详细探讨各类化学氧化技术的反应机理,通过归纳相关二级反应速率常数来评估氧化剂的效果。Antibiotics have been frequently detected in aquatic environments and soils worldwide in recent years due to their extensive production and consumption,which have caused hazards to the ecosystem and human health. Chemical oxidation technologies can decompose antibiotics into non-toxic or less toxic small molecules,which could reduce antibacterial activity,and enhance their biodegradability and mineralization rate. Aiming at the chemical oxidation treatment of antibiotics in water, this paper focuses on three kinds of chemical oxidation technologies: direct ozonation, advanced ozonation,chlorination, Fenton and Fenton-like process, discusses the reaction mechanism of various chemical oxidation technologies in detail, and evaluates the effects of oxidants by generalizing the relevant secondary reaction rate constants.
