三种厌氧促进剂对亚铵废液厌氧发酵的影响

根据亚铵法草浆蒸煮废液的间歇式厌氧发酵试验结果，分析了活性炭、硫酸亚铁和膨润地亚胺废液厌氧发酵的影响。结果表明，当投量为２．５ｇ／Ｌ时，３４种耨氧促进剂都能显著地促进亚铵废液的厌氧发酵；与对照试验相比，可将厌氧系统的３０ｄ累积产气量分别提高１６．１％、１３．９％和２６．１％。本研究还初步探讨了这３种厌氧促进剂的作用机理。

Effects of Three Sorts of Anaerobic Promoter on Anaerobic Digestion of the Waste Liquor from Ammonium Sulfite Pulping of Straws

The effects of activated carbon, ferrous sulphate and bentonite on anaerobic digestion of the waste liquor from ammonium sulfite pulping of straws have been analysed on the basis of the experimental results of anaerobic batch assays with the waste liquor. The results indicate that,with a dose of 2.5 g/L, each sort of the anaerobic promoter can substantially promote anaerobic digestion of the waste liquor, which can increase 30 day total gas production of the anaerobic system by 16.1%,13.9% and 26.1% respectively compared with the control. The action mechanisms of the three sorts of anaerobic promoter have been discussed preliminarily.
