1、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
2、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、构筑物平面及高程、主要构筑物共四张图纸。关键词：啤酒废水；UASB；生物接触氧化；AbstractThisarticleswastomakeapreliminarydesigndealingw
