摘　　要：抗生素在全球范围内广泛使用,产生大量含抗生素的废水。目前,废水常采用生物法进行脱氮。由于抗生素对微生物具有抑制作用,其对生物脱氮也会产生不同程度的影响。本文主要阐述了抗生素对硝化过程、反硝化过程及厌氧氨氧化过程的影响以及微生物抵抗抗生素抑制作用的主要机制,并展望了含抗生素废水处理的研究发展方向。Antibiotics are widely used worldwide. Thus, a large amount of wastewater containing antibiotics is produced. At present, biological nitrogen removal process is often used in the wastewater treatment. The microorganisms can be inhibited by the antibiotics, which could affect the biological nitrogen removal performance.In this paper, the effects of antibiotics on nitrification, denitrification and anaerobic ammonium oxidation process were described. The main mechanisms on the resistance to the inhibition by the antibiotics were summarized. In addition,the further research in the treatment of wastewater containing antibiotics was prospected.
