| 摘 要： | 酒精糟液中含有大量可供酵母吸收利用的物质,经过滤处理后的上清液可以回用至酒精生产.该文以河南省某发酵酒精生产企业酒精生产线为例,通过对影响酒精糟液回用的因素进行分析,确定了最佳回流比和新鲜水添加比例,当回流比为50％,过滤液与清水的比值在1∶2.33左右时,发酵效果最好,提高了酒精糟液的回收利用率.酒精糟滤液回用技术的实施,将减少污染、合理利用资源、实现经济效益和环境效益相统一.

| Abstract: | Alcohol waste contains large amounts of material which is available for yeast;filtered supernatant can be recycling for ethanol production.This paper selected Tianguan Biological Chemical Co.,Ltd.,alcohol production line for the study,some parameters were selected to study the effect on the recycling technology.The results showed that when the reflux ratio was 50% with culture filtrate/fresh water ratio of 1：2.33,the fermentation effect was remarkable.If the recycling technology is implemented,it will reduce pollution,make the resources used reasonably and achieve the unification of the economic and environmental benefits. |
