1、青岛理工 大 学毕业设计用纸 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，最终选择水解酸化 +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
2、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、水解池、生物接触氧化池、沉淀池、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、主要构筑物共八张图纸。 关键词： 啤酒废水；水解酸化；生物接触氧化； 青岛理工 大 学毕业设计用纸 2 Abstract According to the beer effluent treat
