摘要
因抗生素具有高效的抑菌、杀菌作用,被广泛应用于医疗、农业、畜牧和养殖等行业.但人类活动的广泛开展,导致水体环境中抗生素浓度持续增加,对生态系统和人类健康构成严重威胁.本文通过分析水环境中抗生素的主要来源,探讨抗生素对环境和健康的影响,研究几种水体中抗生素主要去除技术的实效,包括物理方法(如吸附、膜分离等)、化学方法(如氯化、臭氧氧化等)、高级氧化技术(如超临界水氧化与过硫酸盐高级氧化等)及生物处理技术(如厌氧生物处理和膜生物反应等).
Abstract
Antibiotics,known for their efficient bacteriostatic and bactericidal properties,are extensively utilized in industries such as healthcare,agriculture,animal husbandry and breeding.However,the wide-ranging human activities have led to a persistent increase in the concentration of antibiotics in the aquatic environment,which poses a severe threat to the ecological system and human health.By analyzing the main sources of antibiotics in the aquatic environment,this paper discusses the impacts they have on the environment and health.Furthermore,it studies substantial results of several main technologies for removing antibiotics in the aquatic environment,including physical methods(such as adsorption,membrane separation,etc.),chemical methods(such as chiorination,ozonation,etc.),advanced oxidation processes(such as supercritical water oxidation and persulfate advanced oxidation,etc.),and biological treatment techniques(such as anaerobic biological treatment and membrane bioreactors,etc.).
