厌氧氨氧化组合脱氮工艺研究进展

Research progress of combined anaerobic ammonium oxidation (ANAMMOX) process for nitrogen removal

摘要:

厌氧氨氧化工艺是一项高效、低耗的生物脱氮工艺,但受限于底物类型、硝氮积累等问题,其在主流应用中仍然面临一些挑战。近些年来,针对上述问题,厌氧氨氧化组合工艺得到了广泛关注。通过对近年来所开发的厌氧氨氧化组合工艺,从工艺原理、优缺点、影响因素、工艺拓展性及其在推广应用中存在的关键瓶颈等角度进行探讨,并结合课题组相关工作,展望了厌氧氨氧化组合工艺在城市生活污水处理中的发展前景。

Abstract:

Anaerobic ammonia oxidation (ANAMMOX) process is an efficient and low-cost biological nitrogen removal process.However,it still faces some challenges in mainstream applications due to the limitation of substrate types and nitrate accumulation.In recent years,the combined process of anammox has been widely studied to solve the above problems.In this paper,the combined processes of anammox developed in recent years are reviewed,and discussed from the process principle,advantages and disadvantages,influencing factors,process extensibility and the key bottlenecks existing in the promotion and application,as well as the relevant work of the subject group.Finally,we take an outlook on the development of the combined anaerobic ammonia oxidation process in municipal domestic wastewater treatment.
