摘要：

相比传统脱氮工艺，厌氧氨氧化（Anammox）以其低耗、高效和环境友好备受青睐，具有广阔的发展前景。基质NO₂^--N难获取，厌氧氨氧化菌（AAOB）生长缓慢且对环境敏感使反应器难启动和不完全脱氮限制因素阻碍了Anammox的工程应用。针对Anammox脱氮应用的限制因素，分析了短程硝化（PN）和短程反硝化（PD）途径获取NO₂^--N的调控，解析了反应器快速启动的环境因素、常用的反应器和高活性污泥，并介绍了PN+Anammox，PN+Anammox+反硝化（SNAD）和PD+Anammox三种一体化Anammox工艺的调控策略。

Abstract:

Compared with the traditional denitrification process, Anammox is favored for its low consumption, high efficiency and environmental friendliness, and has broad development prospects. The limiting factors including difficult to obtain NO₂^--N, the reactor start-up very difficult because of slow growth of AAOB sensitive to the environment, and incomplete nitrogen removal, hinder the engineering application of Anammox process. This article addressed the limiting factors for the application of the Anammox nitrogen removal. The regulation of NO₂^--N obtained by partial nitrification(PN) and partial denitrification(PD) was analyzed, the environmental factors, commonly used reactors and highly activated sludge which determined the rapid start-up of the reactor were discussed, and the regulatory strategies of three integrated Anammox processes including PN+Anammox, PN+Anammox+denitrification(SNAD) and PD+Anammox were introduced.

Key words: Anammox, partial nitrification, partial denitrification, rapid start-up, integrated process
