| 摘 要： | 选择适宜的沼气接种物是提高甲烷含量的有效途径,以鲜牛粪和干杂草为底物,接种四种接种物,4℃下培养,研究不同接种物对沼气中甲烷含量的影响.结果表明,接种根河泥样A组和霍林河泥样B组的产气中最高甲烷含量分别为52.66％和48.04％;接种经低温驯化的接种物C组最高甲烷含量为14.45％;接种加活性炭的低温驯化接种物D组最高甲烷含量为20.08％,不同接种物对沼气中的甲烷含量影响较大.

| Abstract: | Choosing suitable biogas inoculum is an effective way to improve the methane content,the fresh cow dung and dry weeds as the substrate, four kinds of inoculum were inoculated and incubated at 4℃ for researching different inoculum effect on biogas methane content.The results showed that the highest methane content was 52.66% and 48.04% in aerogenesis respectively inoculated Gen river mud samples grouped A and Huolin river mud samples grouped B, the highest methane content was 14.45% inoculated group C biogas slurry at cold acclimation; the highest methane content was 20.08% inoculated group D biogas slurry with activated carbons at cold acclimation; Different biogas inoculums had significant effect on the methane content. |
