厌氧消化过程氨抑制研究进展

摘要

随着厌氧消化理论研究的不断深入,厌氧消化工艺的研发和应用取得了迅速的发展,但处理效率低和运行稳定性差是厌氧消化中普遍存在的问题,其中氨积累引发氨抑制是主要原因之一.文章简述了厌氧消化过程中氨抑制产生的机理及氨抑制的主要影响因素,介绍了氨抑制过程中微生物变化规律研究现状,总结了消除和缓解氨抑制的方法,并提出了厌氧消化氨抑制的重点研究方向.%Anaerobic digestion process have a rapid development with the advanced research of anaerobic digestion theory, but low efficiency and stability was a common problem we must face, and the ammonia inhibition induced by ammonia accumulation was the key factor. In this paper, the mechanism and factors of ammonia inhibition were introduced, and the methanogenism dynamic during ammonia inhibition as well as the methods of alleviating and eliminating ammonia inhibition were summarized simply. In the last, it provided the promising research fields of ammonia inhibition during anaerobic digestion.
