摘要
综述了活性污泥法、膜生物反应器、人工湿地等国内外常见抗生素生化去除方法的优缺点与适用范围,通过工艺对比发现,膜生物反应器和人工湿地能有效去除污水中的抗生素,活性污泥法对抗生素的去除率不高,且选择性较强;污泥龄和水力停留时间对抗生素的去除率有着显著影响,多数情况下反应器的运行改进也能提高抗生素的去除效果。针对抗生素污染问题,提出了采取加强型的复合式处理工艺、开展分区研究、出台相关管理政策等建议。
This paper summarized the merits and demerits, and the scope of application of usual biochemical methods for antibiotics removal at home and abroad, such as activated sludge method, membrane bioreactor, constructed wetlands, etc. Membrane bioreactor and constructed wetland were more effective than activated sludge on removing antibiotics in sewage by comparison their technologies. Activated sludge method had high selectivity. SRT and HRT had significant effects on the removal rate. In most cases, improving the reactor operation could raise the removal efficiency. In view of antibiotic pollution, it gave some suggestions on adopting enhanced compound treatment process, carrying out partition studies and issuing related management policies etc.
