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p H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p H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。[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 p H value of fermentation liquid should be adjust to 5. 0 for hydrogen fermentation; secondly,after hydrogen fermentation,the p H value of fermentation liquid would be adjust to the neutral range（ 6. 5- 7. 5） and add new inoculum to start methane 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 method for co-fermentation for hydrogen and methane production can significantly increase the energy production efficiency of anaerobic biological treatment.
