摘要
对酸性α-淀粉酶应用于拌料酒精废水全回流技术进行了研究,结果表明,采用中温蒸煮,对拌料废水的淀粉质原料直接进行液化糖化,酒精废水全回流循环使用6次为佳,酒精的产量和质量不受影响,从而节约了水资源,降低了生产成本,减轻了废水对环境的污染。
Effect of application of a novel acid-stable a-amylase in recycling of ethanol filtrate was studied. It is showed that the optimum conditions were： cooking by medium temperature, starches in wastewater from mixing of raw materials liquefied and saccharified directly, wastewater from al- cohol recycled 6 times. Application of enzyme could efficiently reduce the pollution of ethanol distilled wastewater, decrease cost of ethanol produc- tion, and didn＇t influence the yield and quality of ethanol, as well.
