摘要
厌氧氨氧化(Anammox)技术在低氨氮浓度城市污水处理中的应用是现今污水生物处理领域研究和工程前沿。城市污水短程硝化/厌氧氨氧化(Partial Nitrification/Anammox,PN/A)工艺的可行性在实验室得以验证,但长期稳定维持仍然缺乏有效策略,实现较为理想的主流厌氧氨氧化(Mainstream Anammox)面临诸多挑战。近年,短程反硝化耦合厌氧氨氧化(Partial Denitrification/Anammox,PD/A)作为新型污水处理技术逐渐受到关注。短程反硝化驱动的部分厌氧氨氧化机理在中国西北某城市污水处理厂主流区得以证明。强化城市污水处理厂厌氧氨氧化菌原位富集,可有效提高脱氮效果并降低处理成本。基于主流城市污水部分厌氧氨氧化(Partial Anammox)的思路,为污水提质增效提供了新的技术路线,具有重要研究价值与工程应用意义。
The application of anaerobic ammonia oxidation(Anammox)technology in municipal wastewater treatment with low ammonia concentration is the frontier of research and engineering.The feasibility of Partial Nitrification/anammox(PN/A)process from municipal wastewater has been confirmed in the laboratory,but there is still a lack of effective strategies for long-term stability.Many challenges need to be overcame before achieving the perfect mainstream anammox(Mainstream Anammox).Recently,partial denitrification coupled with anammox(PD/A)has gradually attracted more and more attention as a novel wastewater treatment technology.The partial anammox driven by partial denitrification has been proved on the mainstream of a municipal wastewater treatment plant(WWTP)in northwest China.Enhancing the in-situenrichment of anammox bacteria in WWTPs could effectively improve the nitrogen removal efficiency and reduce the treatment cost.Partial anammox provides a novel technical route of improving quality and performance for mainstream municipal wastewater treatment,and would have important significance of research and engineering application.
