摘　　要：酒精糟液经离心分离,并通过添加复合酶Fhm-5水解后作为营养液回用于配料的重新利用,提高了原料利用率,降低了水的单耗和污水处理量,缩短了发酵周期,提高了玉米酒精的经济效益。每生产1吨酒精需3吨玉米,排出糟液约为12m3。The waste liquid from ethanol fermentation was centrifuged.And then the complex enzyme,Fhm-5 was added for hydrolysis.The hydrolysate was reused for proportioning as nutrient broth.The utilization of the raw material was improved.Per unit of water consumption and volume of sewage to be treated were reduced.The fermentation time was shortened.The economic benefit of corn based ethanol fermentation was improved.To produce one ton of ethanol three tons of corn were required,and approximately 12 cubic meters of waste liquor were discharged.
