厌氧消化过程中氨氮的抑制浓度和消除方法

Inhibition Concentration and Elimination Method of Ammonia Nitrogen in Anaerobic Digestion Process

参考国内外的研究成果,阐述了氨氮的抑制机理,确定其抑制浓度范围为1.4~7.9 g/L,得出其影响因素包括pH、温度、污泥停留时间、污泥浓度以及Na^+、K^+、Ca^(2+)等。并提出了消除氨氮抑制的有效方法。

Based on the researches in China and abroad,the inhibition mechanism of ammonia nitrogen was expounded,and its inhibiting concentration range was 1.4 - 7.9 g/L. The factors affecting inhibiting concentration included pH,temperature,sludge retention time（SRT）,sludge concentration and ions（Na＋,K＋,Ca2＋,and so on）. On this basis,the effective methods to eliminate the ammonia nitrogen inhibition were put forward.
