摘要 研究了活性碳在啤酒酿造水处理中的作用厦其对啤酒酿造性能的影响。通过对比分析活性碳处理前后的水质指标,发现活性碳可基本去除原水中的游离奈氯.同时对氯消毒副产物(氯仿指标)也有很好的去除作用;同时能去除有机物(总有机碳和耗氧量指标)、絮凝剂残留(铝离子含量)等;能明显改善水质口感;总碱度、残留碱度、总硬度、暂时硬度等指标有所下降,氯化物指标有所上升;Ca、Mg等指标总体略有下降,电导率指标总体略有上升,但这些指标均呈现波动.差异均不显著;但是活性碳单元吸附了原水中带来的大量有机物,从而极易造成出水水质带菌。用活性碳处理前后的水在实验室规模上进行酿造试验,发现经活性碳处理后的水,其酿造过程双乙酰还原速度明显加快.经t-检验分析具有显著的差异。
