酒精清液资源化利用污染物减排技术应用

Application of Pollutant Reduction Technology for Resource Utilization of Alcohol Liquor

发酵酒精醪液经过固液分离后的清液(即压榨滤液或离心清液),污染物浓度高,直接进入污水处理系统处理,处理难度大、成本高、污泥产量大。为进一步提取清液中的有机物,采用管束烘干机和五效蒸发系统处理清液,实现了清液资源化利用污染物减排的目标,实际运行证明,此种方式经济可行,环境减排效果显著。

Alcohol fermentation mash after solid-liquid separation of the supernatant(i.e.squeezing filtrate or centrifugal clear liquid),high concentrations of pollutants,directly into the sewage treatment system,treatment is difficult,high cost and sludge production is big,to extract the organic matter in the supernatant further,using tube bank dryer and five effect evaporation system processing solution,to achieve the goal of clear liquid recycle pollutant emissions,The practical operation proves that this method is economical and feasible,and the effect of environmental emission reduction is remarkable.
