摘要
抗生素是近年来受到环境界普遍关注,具有潜在生态风险的新兴污染物。城市污水处理厂作为水循环和水污染控制的重要环节,是抗生素向环境迁移转化的重要来源。根据目前已有的研究结果,对几类典型抗生素在国内外污水处理厂的分布和迁移进行了综述,详细总结分析了污水厂出水和污泥中的抗生素浓度分布、典型抗生素在污水处理厂的去除效率和吸附降解规律等,并对今后的研究重点及方向进行了展望。
As emerging contaminants with potential ecological risk, antibiotics are universally concerned in recent years. Sewage treatment plant is an important infrastructure for water recycle and water pollution control, and thus a major pathway for migration and transformation of antibiotics. Distribution and migration of typical antibiotics in domestic and overseas sewage treatment plants are reviewed. Concentration of antibiotics in sewage effluents and sludge, removal efficiency of antibiotics in sewage treatment processes, adsorption and degradation of antibiotics are summarized and analyzed. An outlook on research direction and focuses are also proposed.
