摘　　要：抗生素在环境水体的累积是威胁人类健康及生态安全的全球性问题,去除环境中残留抗生素迫在眉睫。本文首先综述了环境中抗生素残留的主要来源及危害。随后,针对微藻处理含抗生素废水的特点,阐述微藻去除抗生素的生物降解、生物累积、生物表面吸附、光合降解和挥发及水解等这5种可能去除机制,比较了这些机制在不同微藻去除抗生素实验研究中的贡献。阐明为提高微藻法去除抗生素的效率,尚需优化藻种的选择和培养条件。最后,讨论了微藻法去除抗生素目前存在的去除不完全、降解产物不明了及缺乏规模化应用等问题,提出可以结合化学、物理和生物方法达到去除要求;通过组学数据等综合分析抗生素降解产物;积累中试数据,为进一步的规模化应用打下基础。The accumulation of antibiotics in environmental water is a global problem threatening human health and ecological security.It is urgent to remove the residual antibiotics in the environment.In this paper,the main sources and hazards of antibiotic residues in the environment were firstly reviewed by summarizing the relevant literature on the treatment of antibiotic wastewater by microalgae in recent years.Then,according to the characteristics of microalgae in the treatment of antibiotic wastewater,five possible removal mechanisms of microalgae for antibiotic removal were described,including biodegradation,bioaccumulation,bio-surface adsorption,photosynthetic degradation,volatilization and hydrolysis.The contributions of these mechanisms in the related experimental studies were compared.Besides,this article clarified the necessity to optimize the selection of algae species and culture conditions in order to improve the removal efficiency of antibiotics by microalgae.Finally,the problems of incomplete removal,unclear degradation products and lack of large-scale application in the removal of antibiotics by microalgae were discussed.It was pointed out that the full removal of antibiotics could be achieved by combining chemical,physical and biological methods;the degradation products of antibiotics could be comprehensively analyzed through omics data;the pilot test data were accumulated to lay the foundation for further large-scale application.
