厌氧氨氧化影响因素及其工艺研究进展

Research Progress of Anaerobic Ammonium Oxidation Process

厌氧氨氧化是一种新型的经济的生物脱氮技术,该过程无需外加有机碳源,不需要曝气,且污泥产生量小,相对于传统脱氮工艺具有显著优势,在处理含高浓度氨氮废水时具有重大的潜在应用价值。近年来,对厌氧氨氧化工艺的研究取得了许多突破性的成果。本文综述了厌氧氨氧化工艺的基本原理、环境影响因素等,以及常用的亚硝化-厌氧氨氧化工艺(Sharon-Anammox工艺)和完全自养生物脱氮工艺(CANON工艺)在实际废水处理中的一些工艺应用。

Anaerobic ammonium oxidation（ Anammox） is biological nitrogen removal process with no additional organic carbon source,aeration and little waste sludge production. Compared with the traditional nitrification / denitrification process,Anammox has significant advantages for the treatment of high ammonia wastewater. In recent years,many breakthroughs have been made in Anammox. This paper summarizes the basic principles and environmental factors of Anammox. Also,the nitrification and anaerobic ammonia oxidation process（ Sharon-Anammox process） and completely autotrophic nitrogen removal process（ CANON process） used in wastewater treatment are reviewed in this paper.
