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，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SBR 处理啤酒废水，UASB＋SBR 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UASB+SBR 。UASB+SBR 的主要组成部分是UASB反应器。本文介绍了有关UASB+SBR 的处理流程和设计的计算、对格、调节池、UASB 池、SBR池、接触氧化池、气浮池、污泥浓缩池等进行了精细的设计和计算。并对主要构筑物UASB池、接触氧化池做了详细的说明。UASB+SBR 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。 关键字 ： 啤酒工业 废水处理 UASB SBR 沼气回收 Abstract Being liquid containing high organic 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 a comparison 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 the combination 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,UASB+SBR 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. UASB the brewery of the treatment, and so on. Through several treatments studying, I make the best way to treatment the wastewater from brewery—UASB+SBR. UASB+SBR is made of reactor. From this literary you can achieve a lot of ways about UASB+SBR .The treatment of calculation, for example, grid accommodator; the engage oxidize of biology flatulence reactor. Concentrate mud pool and make a detailed explanation for the main building. UASB pool and the engaged oxidize of biology flatulence reactor.
