| 摘 要： | 农村常见农业有机废弃物产沼气研究显示,用稻草和杂草替代畜禽粪便作为沼气发酵原材料是可行的.其影响沼气发酵因素主次排序为原料碳氮比>原料固体含量>环境温度>投加不同微量元素,原料碳氮比以25:1为好,固体含量范围8%-14%,发酵温度以30℃为宜,投加微量元素以Co为佳,稻草和杂草投加比例宜控制在60%左右,搅拌能明显提高产气量.

| Abstract: | Study on gas production of some common agricultural organic waste has shown that it is feasible to take dry straw and grass place of the feces as biogas fermentation materials.The primary and secondary impact of methane fermentation factor is that :carbon and nitrogen ratio of raw materials > solid content of raw materials> ambient temperature> adding different trace elements.The results indicated that the appropriate conditions are as follows: carbon nitrogen ratio of raw material as 25:1,the range of soli... |
