摘要:

厌氧氨氧化因其低能耗和高效脱氮而受到广泛关注,该技术在处理高氨氮、低碳氮比废水方面具有极大的应用价值。然而,自养型厌氧氨氧化菌倍增速度缓慢,污泥容易流失,且对生长环境的要求非常严格,导致厌氧氨氧化脱氮技术的应用受到限制。笔者总结了目前主要的4种厌氧氨氧化菌固定化技术的原理、优缺点以及适用场景,阐述了厌氧氨氧化菌固定化技术的最新研究进展,介绍了厌氧氨氧化菌的不同载体材料,并对厌氧氨氧化菌固定化技术的关键影响因素和最佳应用条件进行了总结,最后对厌氧氨氧化菌固定化技术现有研究的不足和未来可能的研究方向进行了总结和展望,以期为该技术的进一步发展提供一些研究思路。

Abstract:

The Anammox technology has great application value in the treatment of wastewater with high ammonia-nitrogen and low carbon nitrogen ratio as its low energy consumption and high nitrogen removal efficiency. However, the application of Anammox nitrogen removal technology is limited due to the slow growth rate of autotrophic Anammox bacteria, the easy loss of sludge and the strict requirements for growth environment. This paper summarized the principles, advantages, disadvantages and applicable scenarios of the four major Anammox bacteria immobilization technologies, and presented the latest research progress of these Anammox bacteria immobilization technologies. The carrier materials used in different immobilization methods were introduced, and the key influencing factors and optimum conditions of Anammox bacteria immobilization technology were summarized. Finally, the deficiency of the Anammox bacteria immobilization technology and the future research direction were summarized and prospected, so as to provide some research ideas for the further development of this technology.

Key words: Anammox, biological denitrification, immobilization techniques
