摘　　要：与传统的硝化-反硝化脱氮工艺相比,厌氧氨氧化工艺在高氨氮污水脱氮方面具有明显的优势。但由于厌氧氨氧化菌倍增时间长,对环境条件敏感,导致厌氧氨氧化工艺的启动时间较长,限制了该工艺的推广应用。回顾了近年来厌氧氨氧化菌富集培养技术的研究进展,分析了进水基质、接种污泥类型与反应器类型对厌氧氨氧化启动过程的影响,对富集厌氧氨氧化菌的技术关键进行了总结。该项研究对厌氧氨氧化工艺的工程应用具有技术指导作用。The anaerobic ammonia oxidation （ANAMMOX） process is a novel and promising alternative to conventional nitrogen removing processes,especially for treating ammonium/nitrogen-rich wastewaters. However,the requirement for a relatively longer start-up time restricts the application of ANAMMOX processes due to a very long doubling time of ANAMMOX bacteria and their susceptibility to environmental conditions. After reviewing the re- search progress in the enrichment techniques of ANAMMOX bacteria in recent years, and the effects of influent sub- strates,inoculation sludge types and reactor configurations on the start-up courses of anaerobic ammonia oxidation are analyzed. The technical essentials of the enrichment of ANAMMOX bacteria are summarized. The research could serve as a technical instruction on the application of ANAMMOX process.
