摘　　要：指出了在厌氧消化工艺的运行管理过程中,对厌氧反应器的进水COD、进水中COD:N:P的比值、进水pH值、有机负荷、温度等常规运行指标较为重视,但忽视了厌氧菌生长对Fe、Ni、Co等一些微量营养物的特殊需求,造成厌氧工艺的运行效果普遍较差,多数厌氧反应器达不到设计负荷,探讨了Fe、Co、Ni等微量营养物对甲烷菌的激活作用。In the process of anaerobic digestion,it is paid more attention to the regular operating indicators,such as inlet COD,the ratio of N.P,the pH value of water intake,organic loading and temperature of the anaerobic reactor, but special demands of anaerobic bacteria on micronutrients such as Fe, Ni and Co are ignored. Thus the performance of anaerobic digestion process is dissatisfied,and most of reactors failed to attain the calculated load. It is reported that micronutrients such as Fe,Ni and Co,can activate methanobacteria.

关 键 词：厌氧消化 甲烷菌 微量营养物
