摘要
本文采用新鲜的奶牛粪便为原料,配制成固含量为12%的发酵料液,利用连续厌氧发酵装置进行高温厌氧消化,考察不同搅拌时间对厌氧发酵性能的影响。结果表明,每天搅拌6h可有效抑制VFA的积累,提高产气量,提高沼气质量。
To study the influence on anaerobic digestion by different mixing times, experiments were carried out using fresh dairy manure by continuous anaerobic fermentation device. The solid content of fermentation liquid is 12 percent. Results showed that the quantity and character of biogas were enhanced,The accumulation of VFA was restrained, when mixing times are 6 hour every day.
