1、啤酒车间废水处理工艺初步设计毕业设计摘要本文针对啤酒车间废水处理工艺进行初步设计。啤酒废水含有许多有机的物质，这些有机物浓度较高，虽然无毒，但易于腐败，排入水体要消耗大量的溶解氧，对水体环境造成严重危害。啤酒废水中BOD5/CODcr值高，在50％及以上，非常有利于生化处理。同时生化处理与物理法、化学法相比较；一是处理工艺比较成熟；二是处理效率高，CODcr、BOD5去除率高，一般可达80％~90％以上；三是处理成本低（运行费用省）；经过对各种处理工艺的对比，最终选择UASB+生物接触氧化作为处理工

2、艺。本工艺流程设有格栅、调节池，对污水进行预处理，去除水中较大的悬浮颗粒和调节水质水量。生化处理采用生物接触氧化法，可提高有机物去除效率。沉淀池用来进行泥水分离。本流程简单稳定，对水量、水质的变化有很强的适应能力，同时确保出水的COD、BOD和SS以及总氮，总磷指标达到广东省地方标准《水污染排放限值》一级标准。通过初步预算，该工艺也将带来可观的经济效益和良好的环境效益。本文对格栅、调节池、UASB反应器、生物接触氧化池、二沉池、污泥池等主要构筑物进行计算，编制设计说明书，并绘制工艺流程、构筑物平面及
