磺胺甲恶唑对污水生物脱氮除磷的影响及机制研究

Effect and mechanism of sulfamethoxazole on biological nitrogen and phosphorus removal of wastewater

磺胺甲恶唑作为磺胺类药物的典型代表在水环境中检出频率较高,其在污水处理厂中的残留会对污水生物脱氮除磷过程产生较大影响。近年来国内外学者针对磺胺甲恶唑在生物脱氮除磷过程中的影响及机制已展开了相关研究。阐述了磺胺甲恶唑在污水处理厂中的残留现状,分析了其对生物脱氮除磷过程的影响及相关机制,以期对未来深入研究磺胺甲恶唑对污水生物处理工艺产生的影响提供借鉴。

As a typical representative of sulfonamides,sulfamethoxazole can be detected with high frequency in water environment,and its residue in sewage treatment plant will have a great impact on the biological nitrogen and phsphorus removal process of sewage.In recent years,scholars at home and abroad have carried out relevant research on the influence and mechanism of sulfanethoxazole in the process of biological nitrogen and phosphorus removal.The residue status of sulfamethoxazole in sewage treatment plant and its impact on biological nitrogen and phosphorus removal process were elaborated with related mechanism analyzed at the same time,which would provide reference for the further study of the impact of sulfamethoxazole on sewage biological treatment process in the future.
