Abstract:

The combined SHARON (Single Reactor High Activity Ammonia Removal Over Nitrite)-ANAMMOX (Anaerobic Ammonium Oxidation) process has un-substituted superiority in treating ammonium-rich wastewater characterized by lowering (super low) C/N ratio，up to 25% of the oxygen demand and saving 40% of the carbon demand. Some latest research findings and applications of the SHARON-ANAMMOX process have been reviewed. The control conditions for the SHARON process and the possible mechanism of the ANAMMOX have been summarized. The feasibility of the SHARON-ANAMMOX process realized in the way of immobilized microorganisms is discussed. The paper also puts the emphasis on the combined process in the future.

Key words: anaerobic ammonium oxidation, immobilized microorganisms, biological denitrification

摘要：

亚硝化-厌氧氨氧化联合工艺在处理低(超低)C/N比高浓度含氮废水方面有着不可替代的优越性,可节省25%的供气量和40%的有机碳。作者回顾了近年来国内外对亚硝化-厌氧氨氧化工艺的研究和应用进展,概括了亚硝化反应的主要控制因素和厌氧氨氧化可能的反应机理。对亚硝化和厌氧氨氧化在固定化微生物技术中的实现进行了可行性的探讨,并对今后联合工艺研究的重点进行了展望。
