The nitritation-anammox process is an efficient and cost-effective approach for biological nitrogen removal, but its application in treating mainstream wastewater remains a great challenge. Mainstream nitritation-anammox processes could create opportunities for achieving energy self-sufficient, or energy-generating water resource recovery facilities. Significant advancements have been achieved via pilot- and full-scale trials to overcome the major obstacles under mainstream conditions, such as repression of nitrite-oxidizing bacteria, limiting the overgrowth of denitrifiers, and effective selection and retention of ammonia-oxidizing bacteria and anammox bacteria. This review paper intends to provide a detailed update of research progress on mainstream nitritation-anammox processes, discuss metabolic interactions, and examine major challenges and possible solutions towards the future development.
亚硝化-厌氧氨氧化工艺是一种高效、经济的生物脱氮方法，但将其应用于处理主流废水仍然是一个巨大的挑战。主流亚硝化-厌氧氨氧化工艺为实现能源自给或能源型水资源回收设施创造了机会。通过中试和全规模试验取得了重大进展，克服了主流条件下的主要障碍，如抑制亚硝酸盐氧化菌、限制反硝化菌的过度生长，以及有效选择和保留氨氧化菌和厌氧氨氧化菌。本文旨在详细介绍主流亚硝化-厌氧氨氧化工艺的研究进展，讨论代谢相互作用，并探讨未来发展的主要挑战和可能的解决方案。
