【Abstract】 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.更多还原
