The anaerobic ammonium oxidation (anammox) process has the advantages of high efficiency and low energy consumption, so it has broad application prospects in biological denitrification of wastewater. However, the application of anammox technology to existing wastewater treatment is still challenging. The main problems are the insufficient supply of nitrite and the susceptibility of anammox bacteria to environmental factors. In this paper, from the perspective of the diversity of anammox bacteria, the habitats and characteristics of anammox bacteria of different genera were compared. At the same time, laboratory research and engineering applications of anammox technology in treating wastewater from different sources were reviewed, and the progress of and obstacles to the practical application of anammox technology were clarified. Finally, a focus for future research was proposed to intensively study the water quality barrier factors of anammox and its regulation strategies. Meanwhile, a combined process was developed and optimized on this basis.
厌氧氨氧化（anammox）工艺具有高效、低能耗的优点，在废水生物脱氮方面具有广阔的应用前景。然而，anammox 技术在现有废水处理中的应用仍然具有挑战性。主要问题是亚硝酸盐供应不足和 anammox 细菌对环境因素的敏感性。本文从 anammox 细菌的多样性角度出发，比较了不同属 anammox 细菌的栖息地和特性。同时，综述了 anammox 技术在处理不同来源废水方面的实验室研究和工程应用，阐明了 anammox 技术实际应用的进展和障碍。最后，提出了未来研究的重点，旨在深入研究 anammox 的水质障碍因素及其调控策略。同时在此基础上开发并优化了组合工艺。
