酒精废水处理主要方法 The main method of alcohol wastewater treatment 酒精糟虽然无毒，但是污染负荷高成酸性。根据酒精生产的原料不同，其酒精糟的综合利用和处理采用不同的方法。 Although the alcohol is not toxic, the pollution load is highly acidic. Depending on the ingredients of alcohol production, the combined use and treatment of alcohol is different. 1、玉米酒精糟的综合利用 The comprehensive use of corn ethanol 玉米酒精糟生产DDGS，既能较彻底的消除污染，使废水处理达标，又能获得高质量的蛋白饲料。但是DDGS生产设备投资大，能耗高（1tDDGS需要200kw?h电耗，蒸汽2.7t，水耗250t），技术要求高，所以国内只有一部分企业实现DDGS生产，部分企业仍采用先进行固液分离，滤渣生产DDG，做饲料，滤液部分回用生产，部分经生化处理，逐步实现酒精糟生产DDGS。 The production of the DDGS, the corn ethanol, can eliminate the pollution completely, make the waste water to meet the standards, and obtain the high quality protein feed. But DDGS production equipment investment is big, high energy consumption (1 200 kw TDDGS need? H power consumption, steam 2.7 t, water consumption of 250 t), high technical requirements, so only part of domestic enterprises realize DDGS production, some enterprises still adopt to solid-liquid separation, filter residue production DDG, do feed and filtrate part recycle production, part of the biochemical treatment, to gradually realize the alcohol producing DDGS. 2、薯干酒精糟的综合利用 2, the comprehensive use of the dry alcohol 部分企业将薯干酒精糟经厌氧+好氧处理，该方法COD去除率可达到80%。还有企业将酒精糟采用固液分离，滤液回用生产或者经生化处理达标，滤渣直接做饲料。 Some enterprises have treated the dioxy alcohol, which is treated by anaerobic and aerobic, which can be removed by 80% of COD. There is also a company that USES the solid liquid to separate the alcohol, and the filtrate is recycled into the production or the biochemical treatment, and the filter is used directly for the feed. 用厌氧消化处理酒精废醪经过30多年的研究实践，已证明是一种切实可行的高效产能的处理方法，得到国内外普遍的承认和应用。我国现行的酒精废醪治理工程中绝大多数采用了厌氧消化工艺。 Deal with waste mash with anaerobic digestion after 30 years of research practice, has been proved to be a practical and efficient production capacity of processing method, get general recognition and application at home and abroad. In our country, the majority of the existing alcohol waste mash management project adopts anaerobic digestion process. 3、糖蜜酒精废水处理方法 The method of treating the sugar and honey liquor 目前，对糖蜜酒精糟采用浓缩燃烧或者浓缩后制作颗粒肥料用，对综合废水仍采用二级生化处理技术。 At present, the use of concentrated combustion or concentrated production of granule fertilizer for the use of sugar and honey is still used in the secondary biochemical treatment.
