中文摘要： 饮用水中抗生素的问题已引起高度重视，微量抗生素在饮用水深度处理中的去除机制成为急需研究的课题。本课题主要研究饮用水臭氧/活性炭催化氧化-生物活性炭工艺中典型抗生素的催化氧化途径与机理、活性炭生物共代谢降解及联合工艺的耦合去除机制。通过对不同结构抗生素在催化臭氧氧化过程中的形态转化和活性炭表面结构性质的构效关系研究，探索该催化体系下抗生素的催化氧化途径和机理；研究贫营养水质因素下活性炭生物膜生物共代谢作用对抗生素及其氧化产物的去除机制和影响效应、活性炭炭层生物膜细菌抗生素抗性基因与共代谢效能的关联性；研究催化臭氧氧化与活性炭联合工艺中炭层生物共代谢及抗性基因对催化臭氧化的感应效应及影响机制，揭示臭氧/活性炭催化臭氧化与生物炭联合工艺去除抗生素的耦合效应与机制，为提高抗生素在催化臭氧化-活性炭工艺中的协同去除效率提供科学依据。

英文摘要： Concerns about antibiotics in drinking water are greatly increasing worldwide; the removal mechanisms of trace antibiotics in the advanced treatment of drinking water have become an urgent and challenging problem. The main research subjects of this project are the catalytic ozonation mechanism and pathway, the activated carbon biological cometabolic degradation process and the removal mechanisms of these two coupled processes in the treatment of typical antibiotics in drinking water by combined catalytic ozonation/activated carbon treatment process. Through research of catalytic oxidation pathway and morphological transformation in the catalytic ozonation of trace typical antibiotics of different structure and morphology in drinking water, highly efficient catalytic approach to improve the removal efficiency of antibiotic in micro-polluted source water are investigated, and the environmental factors and mechanisms affecting the catalytic pathway are also studied. The mechanism and affecting factors of the removal of antibiotics and their oxidation products in oligotrophic water conditions by activated carbon layer biological cometabolism are studied, and the distribution of biofilm bacteria and antibiotic resistance genes in activated carbon layer are investigated. The response mechanisms of activated carbon lay
