废水中抗生素降解和去除方法的研究进展

摘要

环境中已经广泛检测到抗生素的存在,这是因为传统的废水处理工艺不能有效去除废水中的抗生素.为了防止污染的扩散,人们开始研究抗生素的去除方法.本文参考国内外文献总结了近几年来抗生素去除方法的研究近况.主要包括:(1)抗生素的定义及主要分类；(2)环境中抗生素的来源；(3)抗生素的去除方法(传统处理法、氧化法、吸附法、电化学处理法、薄膜法、超声法、微生物降解法等),详细阐述了每一种处理方法的作用机理及去除效果；(4)对各种抗生素处理方法进行优缺点的总结并对未来应用做了展望.%Abstract In recent years,antibiotics have been considered as emerging pollutants in the water environmental pollution.In order to prevent the contamination,the removal methods of antibiotics have been studied.Referring to other published literatures in recent years,this review summarized the recent progress of researches in the removal of antibiotics from waste water,mainly including (1) Definition and classification of antibiotic; (2) Sources of antibiotics in the environment; (3) The removal methods of antibiotics (such as conventional treatment,oxidation,adsorption,electrochemical,membrane,ultrasonic,microbial degradation processes and son on),and the following section introduce the mechanism and removal efficiency of each method.(4) Finally,the merit and disadvantage of each removal method is analyzed and their prospects of application are also presented.
