摘要
[目的]探讨猪粪厌氧发酵先产氢气后产甲烷的能源转换效率，以期提高传统厌氧发酵的能源转换效率。[方法]将发酵料液的pH调节至4．5～5．5，首先进行厌氧发酵产氢气，产氢结束后将产氢发酵液的pH调节至6．5～7．5进行厌氧发酵产甲烷。[结果]猪粪厌氧发酵联产氢气和甲烷的产能效率为44．06％，明显高于猪粪单独厌氧发酵产氢的产能效率（14．43％）以及猪粪单独厌氧发酵产甲烷的产能效率（32．80％）。[结论]厌氧发酵联产氢气和甲烷能有效提升传统厌氧发酵产能效率。
Abstract
Abts ract [Objective] The aim was to explore energy production efficiency of hydrogen and methane production by co-fermentation of pig dung to improve the energy production efficiency of anaerobic biological treatment.[Method] The method for co-fermentation for hydrogen and methane production was described following: first, the pH value of fermentation liquid should be adjust to 5.0 for hydrogen fermentation;secondly, after hydrogen fermentation, the pH value of fermentation liquid would be adjust to the neutral range (6.5-7.5) and add new inoculum to start meth-ane fermentation.[Result] The energy conversion efficiency of pig dung via co-fermentation for hydrogen and methane production was 44.06%, which was 14.43%over the hydrogen fermentation of pig dung and 32.80%over the methane fermentation of pig dung.[Conclusion] The meth-od for co-fermentation for hydrogen and methane production can significantly increase the energy production efficiency of anaerobic biological treatment.
