化学工程与工艺专业毕业论文--3000吨每天啤酒废水处理装置工程设计 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EGSBCASS EGSBCASS 的主要组成部分是EGSB反应器本文介绍了有关EGSBCASS 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EGSBCASS 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 关键字 啤酒工业 废水处理 EGSB CASS 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 treatmentEGSBCASS 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 breweryEGSBCASS EGSBCASS is made of reactor From this literary you can achieve a lot of ways about EGSBCASS The treatment of calculation for example grid accommodator the engage oxi
