1、设计总说明木设计为某啤酒厂啤酒废水处理工艺设计。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，故其牛化需氧量也较大。该啤酒废水处理厂的处理水量为5000m3/do原污水中各项指标为：BOD浓度为1200mg/L,COD浓度为2000mg/L,SS浓度为700mg/Lo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<20mg/L,COD<100mg/L,SS<70mg/Lo经分析知该处理水质属易牛物降解又无明显毒性的废水，可采用两
2、级牛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，可有效去除污水屮的BOD、CODo本设计工艺流程为：啤酒废水T格栅T污水提升泵房T调节沉淀池TUASB反应器T预曝气沉淀池-SBR池一>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GeneralinformationofdesignThisde
