1、毕业论文毕业设计（论文）题目：啤酒废水处理设计58毕业论文设计总说明本设计为xx市xx啤酒有限公司啤酒废水处理设计。设计程度为初步设计。啤酒废水水质的主要特点是含有大量的有机物，属高浓度有机废水，故其生化需氧量也较大。该啤酒废水处理厂的处理水量为3000m3/d，不考虑远期发展。原污水中各项指标为：BOD浓度为1200mg/L,COD浓度为1500mg/L，SS浓度为300mg/L。因该废水BOD值和COD值较大,不经处理会对环境造成巨大污染，故要求处理后的排放水要严格达到国家二级排放标准,即：BOD≤30mg/L，COD≤100mg/
2、L，SS≤70mg/L。经分析知该处理水质属易生物降解又无明显毒性的废水，可采用两级生物处理以使出水达标。一级处理主要采用物理法，用来去除污水中的悬浮物质和无机物。二级处理主要采用生物法,包括厌氧生物处理法中的UASB法和好氧生物处理法中的SBR法，可有效去除污水中的BOD、COD。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→UASB反应器→预曝气沉淀池→SBR池→处理水（污泥）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。关键词：啤酒废水处理,高浓度有机废水,UASB法,SBR法58毕
