综述了炔雌醇(EE2)的主要危害以及国内外城市污水处理厂对其的处理能力,指出现有污水处理厂对EE2的去除效率仍较低,微生物降解是去除EE2等类固醇雌激素的主要途径。总结了EE2微生物降解的代表性研究成果,重点分析了EE2在异养代谢降解、硝化共代谢降解、异养共代谢降解、微生物协同降解和降解功能基因等方面的研究进展,提出共代谢是EE2的主要去除机制,未来可开展微生物学共代谢机制研究,以提升EE2的去除效率,有效控制水生态和健康风险。 |

Abstract: |
The main hazards of Ethinylestradiol(EE2) and the treatment capacity of municipal wastewater treatment plants at home and abroad were reviewed. It was pointed out that the removal efficiency of EE2 in existing wastewater treatment plants is still low, and microbial degradation is the main way to remove EE2 and other steroid estrogens. The representative research results of EE2 microbial degradation were summarized, and the research progress of EE2 in heterotrophic metabolism, nitrification co metabolism, heterotrophic co metabolism, microbial synergistic degradation and functional genes was emphatically analyzed. It was proposed that co metabolism is the main removal mechanism of EE2. In the future, the research on microbial co metabolism mechanism could be carried out to improve the removal efficiency of EE2 and effectively control the water ecological and health risks. |
