摘要
啤酒废水中有机物含量较高,如直接排放,既污染环境又降低啤酒工业的原料利用率,为此,许多学者和厂家对啤酒废水的处理和利用技术进行研究,对几种常见的处理利用技术进行了比较,得出结论:单一的处理和利用技术不能从根本上解决啤酒废水的污染问题,只有将多种技术结合使用,才能达到经济效益和环境效益的统一。本文根据前人的研究成果综述了啤酒废水处理和利用的现状,有针对性的对啤酒废水自身的特性,通过对酸化―SBR 处理啤酒废水,EGSB+CASS 法处理啤酒废水,新型接触氧化法处理啤酒废水,生物接触氧化法处理啤酒废水,上流式厌氧污泥床(UASB )等处理啤酒废水的几种处理方法的详细分析,确定最佳方案即用EGSB+CASS 。EGSB+CASS 的主要组成部分是EGSB反应器。本文介绍了有关EGSB+CASS 的处理流程和设计的计算、对格、调节池、EGSB 池、CASS池、污泥浓缩池等进行了精细的设计和计算。并对主要构筑物EGSB池、CASS做了详细的说明。EGSB+CASS 处理高浓度有机废水,其关键是培养出沉降性能良好的厌氧颗粒污泥。采用此工艺,不但使处理流程简洁,也节省了运行费用,在降低废水浓度的同时,还可以回收在处理过程中所产沼气作为能源的利用。以便我为进一步探讨效益资源型处理技术提供借鉴。
本设计工艺流程为:
啤酒废水→格栅→污水提升泵房→调节沉淀池→EGSB反应器
→ CASS池→处理水
整个工艺具有总投资少,处理效果好,工艺简单,占地面积省,运行稳定,能耗少的优点。

Abstract
Being liquid containing anic pollutants, brewery wastewater may not only lead to environmental pollution, but also decrease the utilization ratio of raw material used in beer production. Therefore, many scholars and breweries have paid much attention to developing new techniques for treating and making use of brewery wastewater. This paper makes parison among various new techniques on the basis of analyzing the sources and characteristics of brewery wastewater. It is concluded that a single technique can not effectively remove the contamination from brewery wastewater, and only bination of various techniques can achieve great benefits both in economy and in environment. Thus, used the present conditions. Make a focalization, for the character of the wastewater of the brewery, with the acid-SBR the brewery of treatment,EGSB+CASS the brewery of the treatment ,the new type of the brewery of the treatment ,the engage oxidize of biology to the brewery of the treatment. EGSB the brewery of the treatment, and so on. Through several treatments studying, I make the best way to treatment the wastewater from brewery—EGSB+CASS. EGSB+CASS is made of reactor. From this literary you can achieve a lot of ways about EGSB+CASS .The treatment of calculation, for example, grid modator; the engage oxidize of bi
