糖蜜酒精废液经蒸发浓缩后制成干粉减水剂、配制生物有机肥等资源化利用是行业内推荐采用的成熟工艺技术。但酒精废液蒸发浓缩通洗罐水水量大、挥发酸高、COD 含量高是一直困扰该工艺的问题。本技术通过对通洗罐水进行沉降、油质分离、灭菌处理等工序，使其挥发酸达到工艺用水指标要求，把处理后的通洗罐水作为工艺用水添加至糖蜜稀释箱，使糖蜜酒精厂的废水产生量削减20%，单位成品废水产生量小于10 m3/kL，达到酒精制造业清洁生产(HJ581-2010)一级水平。

Molasses alcohol wastewater after evaporation and concentration could be made into water reducing agent and compounded into bio-organic fertilizer, which is a mature process recommended by industry. But the problems including huge water consumption, high volatile acid and massive content of COD are making it very difficult for the process. Through a series of process, such as settlement, oil separation and sterilization, this technology makes the volatile acid of cleansing water reach the requirements for industry consumption. At the meantime, the wastewater production reduces by 20%and the wastewater amount per final product is less than 10 m3/kL with treated wastewater added to molasses dilution tank, which achieves the first grade of clean production for alcohol manufacturing (HJ581-2010).
