摘要:

异养硝化-好氧反硝化(HN-AD)菌能够利用有机碳源,同时在单一有氧条件下实现同步硝化反硝化,使HN-AD技术备受关注。但由于实际废水所在环境具有复杂性,极大地影响了生物脱氮效率。综述了在极端pH、温度、重金属、难降解有机物和盐度等恶劣环境下HN-AD菌的研究进展与应用情况,并对HN-AD技术的未来发展提出建议并做出展望。

关键词: 异养硝化-好氧反硝化, 生物脱氮, 恶劣环境

Abstract:

Heterotrophic nitrification-aerobic denitrification(HN-AD) bacteria can utilize organic carbon sources while achieving simultaneous nitrification and denitrification under a single aerobic condition, making HN-AD technology attracting much attention. However, due to the complexity of the environment of the actual wastewater located, the efficiency of biological nitrogen removal has been greatly affected. The research progress and application of HN-AD bacteria in harsh environments such as extreme pH, temperature, heavy metals, refractory organic matter and salinity were reviewed, and suggestions and prospects for the future development of HN-AD technology were put forward.

Key words: heterotrophic nitrification-aerobic denitrification, biological nitrogen removal, harsh environment
