| 摘 要： | 通过在畜禽粪便中添加稻草进行混合干式发酵来产生沼气,研究了干式发酵的启动特性和产气性能,考察了温度、接种液数量对发酵效果的影响。试验结果表明,在发酵原料C/N=25～30、TS=20%和T=(36±1)℃的条件下,以驯化后的浓缩池污泥作为接种物,实现了干式发酵的快速启动;相比于鸡粪和猪粪,风干的牛粪产气稳定且气量较多;对干式发酵进行接种是必需的,随着接种液数量增多,产气量增大,适宜的接种液比例为10%;温度对干式发酵产气效果影响较大,建议实际工程中选择中温条件进行干式发酵。 |

| Abstract: | In this paper dry anaerobic co-digestion of animal manure and straw was conducted to produce biogas.Startup characteristics and biogas production perform of dry digestion were studied,and the effect of operation temperature and incubation amount on dry digestion was also investigated.The study results showed that under the conditions of C/N=25～30,TS=20% and T=（36±1）℃,dry digestion could start up quickly with acclimated thickening sludge as incubation sludge.Compared to chicken manure and pig manure,dry digestion of cow manure proceeded steadily with high biogas yield.It was found that incubation was necessary in the process of dry digestion and biogas yield increased with more incubation amount.The appreciate incubation ratio was about 10%.Temperature change had apparent effect on biogas production,it was suggested that mesophilic temperature should be chosen in the scaled project of dry digestion. |
