摘　　要：由于抗生素的广泛使用,目前在地表水、地下水、饮用水、污泥及土壤等环境介质中都检测到了抗生素的残留。抗生素在环境中的持续暴露可能诱导耐药菌株的产生,对生态环境和人类健康具有潜在的巨大危害性,因此抗生素的污染问题越来越受到公众关注。近年来,考察抗生素在城市污水厂生物处理工艺中的去除效果已成为研究热点。在分析城市污水处理厂中抗生素主要来源的基础上,探讨了传统活性污泥法、序批式活性污泥法、膜生物反应器等生物处理工艺对抗生素的去除效果,分析了污泥停留时间、温度、吸附作用和水力停留时间等因素对抗生素去除效果的影响。Antibiotics are frequently detected in various environmental media such as surface water, underground water, drinking water, sludge and soils due to their wide usage around the world. The durative exposure of antibiotics in the environment may cause generation of drug-resistant strain, thus posing a great risk to ecosystems and human health. As a result, antibiotics pollution is attracting more and more public attention. In recent years, the removal of antibiotics in biological treatment processes in municipal sewage treatment plants has become a research focus. The major sources of antibiotics in municipal sewage treatment plants were analyzed, and the removal efficiencies of antibiotics in several biological treatment processes were discussed, including the conventional activated sludge process, sequencing batch reactor and membrane bioreactor. Besides, several influencing factors on the removal efficiencies of antibiotics were analyzed, including sludge residence time, temperature, adsorption and hydraulic retention time.
