摘要
厌氧氨氧化技术具有低能耗、低成本、环境友好等优点,已成为废水生物脱氮领域的研究热点。文中通过总结厌氧氨氧化技术的现有研究应用成果,综述了其常见的工艺和反应器类型,回顾了国内外工程应用进展,并讨论分析了该技术在市政污水主流工艺应用中遇到的技术瓶颈和潜在问题。目前的研究应用表明,近年来国内外研究者在主流厌氧氨氧化工艺的研究和开发方面做出了巨大努力,并取得很多突破性进展。尽管目前主流工艺应用仍面临工艺启动缓慢、低温难稳定运行、厌氧氨氧化菌难保留等技术难点,但该工艺的可行性已通过各种规模的实践得到证明,随着污水资源化的推进,对该技术的研究和应用将得到进一步发展。最后,文中对厌氧氨氧化工艺的发展和实践应用提出了一些建议,以期为我国未来厌氧氨氧化技术的研究和应用提供有益参考。
Anammox technology has become a research hotspot in the field of wastewater biological denitrification due to its low energy consumption,low cost,and environmental friendliness.Existing research and application results of anaerobic ammonia oxidation technology are summarized,common processes,reactor types,progress of domestic and foreign engineering applications are reviewed,technology bottlenecks and potential problems in the mainstream application of municipal wastewater are discussed.Current researches and applications shows that researchers have made great efforts in the research and development of mainstream anaerobic processes in recent years,and have made many breakthroughs.Although current mainstream applications still face many challenges,such as slow process start-up,hard to run stably in low tempreture and difficult to maintenance anammox bacteria,but the feasibility of the process has been proven through various scales of practice.With the advancement of wastewater recycling,the research and application of this technology will be further developed.Finally,some suggestions on the development and practical application of anammox technology are put forward in order to provide a favorable reference for the future research and application of anammox technology at home.
