The invention discloses a method for preparing ethanol by semi-continuous fermentation of surface-immobilized yeast. The method includes fastening a fiber material into a spherical grid to serve as animmobilization medium, filling a fermentation tank with the immobilization medium, fastening the yeast to a fiber carrier through adsorption to carry out fermentation, completing the fermentation after 2-4 batches are completed, discharging materials into another fermentation tank when the alcohol content of each batch reaches 8-10% (v/v), supplementing the materials until the fermentation tank is full, and continuing to discharge the materials into another empty tank until the alcohol content reaches 8-10% (v/v); carrying out semi-continuous fermentation by repeating the previous steps. Themethod has the advantages of low production cost, convenience in operation, stability in process, high fermentation strength, high product yield, and long-lasting and high activity of the immobilizedyeast.
