The invention discloses a method for preparing ethanol by straw biological fermentation, which comprises straw pretreatment, enzyme treatment, fermentation and purification. The method adopts straw biological fermentation to produce ethanol, has wide sources of raw materials, low cost, green environmental protection and high conversion rate. The prepared ethanol has almost no straw odor, overcomes the disadvantages of the existing bioethanol preparation method, such as low conversion rate, contamination of the fermentation process, large production energy consumption, and the like, and has the advantages of high efficiency, environmental protection and the like. |
