| 摘 要： | 研究了木薯渣的酸化特性和不同接种率（60%、70%、80%）对厌氧发酵产沼气的影响。试验结果表明，木薯渣极易酸化，但厌氧发酵甲烷化是可行的，在试验采用的接种率中，70%的接种率能调控发酵系统的pH、VFA浓度在正常范围，产气能顺利启动和进行，产气率和最高甲烷含量分别为249.35 ml/g VS和48.16%，优于其他两组，为木薯渣厌氧发酵产沼气的深化研究和应用提供了参考依据。

| Abstract: | The acidification characters of cassava dregs and the impact of different inoculation rate(60%,70% and 80%) on the biogas production by anaerobic fermentation were studied.The experimental results show that the acidification of cassava dregs was very easy and quick,but methanation by anaerobic fermentation was feasible.Among the inoculation rates used in the experiment,70% inoculation rate can control pH and VFA concentration in normal range,gas production can start and keep smoothly,the gas production rate... |
