摘    要:为研究微生物预处理技术对秸秆发酵制沼气的影响,采用混合菌剂对油菜秸秆进行预处理,利用红外光谱分析仪和扫描电子显微镜对预处理前后的秸秆进行分析。结果表明,混菌共发酵预处理11 d后油菜秸秆的纤维素、木质素、半纤维素降解率分别达到了37.4%、28.9%和29.9%。混菌共发酵预处理使油菜秸秆的木质纤维素内部结构发生较大改变,产生很多裂缝和空洞。以油菜秸秆为原料进行沼气发酵试验,发现预处理后的秸秆日产气量最高峰值较未处理的提高了37.6%,累计产气量提高了17.8%。由此可见,通过混合菌剂降解油菜秸秆中的纤维素、木质素和半纤维素,可促进秸秆生物质转化为沼气。

关 键 词:微生物,沼气,油菜秸秆,预处理

Abstract:Rape straw treated by compound microbial fermentation was analyzed by using infrared spectra analysis apparatus and scanning electron microscope. The effects of biological pretreatment on biogas production were studied by using rape straw. The results showed that the cellulose and lignin and hemi cellulose degradation rate of rape straw, which was fermented by compound microbial agent for 11 days, reached 37.4% and 28.9% and 29.9%, respectively. The structure of pretreated straw has a great change and some crack and cavity, observed by SEM, were found in rape straw pretreated by compound microbial fermentation. The results of biogas fermentation experiment, rape straw as raw materials, showed that gas production peak daily and total biogas yield have remarkable increase, which was 37.6% and 17.8%, respectively. So, degraded the cellulose and lignin and hemi cellulose in rape straw by compound microbial inoculants could promote converting straw biomass into biogas.
Keywords:microorganisms  biogas  rape straw  pretreatment
