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。

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. |
