生物法去除水环境中磺胺甲恶唑的研究进展

Progress in the Study of the Removal of Sulfamethoxazole by Biological Methods in Water Environment

磺胺甲恶唑作为使用频率最高的磺胺类抗生素之一,在水环境中频繁被检出。磺胺甲恶唑长期存在于自然水体中极易导致抗性细菌的产生,严重威胁到水生生物和人类的健康和安全。从磺胺甲恶唑的特性和来源、微生物降解磺胺甲恶唑及不同水处理工艺去除磺胺甲恶唑的效能等方面对磺胺甲恶唑的生物处理进行了综述。结合不同类型微生物降解磺胺甲恶唑的效果及不同水处理工艺的特点,提出好氧颗粒污泥结合强化功能微生物的新型工艺是潜在的处理磺胺甲恶唑的有效方法。

As one of the most frequently used sulfonamide antibiotics, sulfamethoxazole is often detected in water environment. The long-term existence of sulfamethoxazole in natural water can easily induce the occurrence of antibiotic resistance bacteria, which seriously threaten the health and safety of aquatic organism and humans. This work reviewed the characteristics and sources of sulfamethoxazole, the microbial degradation efficiency of sulfamethoxazole, and the removal performance of sulfamethoxazole in different wastewater treatment processes. Based on the degradation efficiencies of sulfamethoxazole and the characteristics of diverse treatment processes, a novel process of combining aerobic granular sludge with the bioaugmentation of functional microorganisms has been proposed to be an effective way for the sulfamethoxazole treatment.
