玉米秸秆干发酵产沼气试验研究

Study on Dry Anearobic Fermentation of Corn Straw

研究添加微生物菌剂、沼渣堆沤对玉米秸秆干发酵产沼气的影响。结果表明:经过微生物菌剂、沼渣堆沤后的玉米秸秆在干发酵过程中日产气量高于对照,其中添加微生物菌剂处理的玉米秸秆显示出较好的日产气能力,累积产气量最高,沼气甲烷含量潜力最强,说明玉米秸秆干发酵时添加微生物菌剂进行堆沤预处理的方法最好。

The effects of corn straw pile fermentation with microbial agent and dregs on dry fermentation were studied. The results showed that the day biogas production with corn straws pretreated with microbial agent and dregs was higher than the control. The treatment of adding microbial agent showed higher day biogas production, the largest accumulative biogas production and better potentiality of methane content. The results indicated that the corn straw pile fermentation with microbial agent on dry fermentation was the best treatment.
