摘要

豆制品营养丰富，含有大量的蛋白质和氨基酸，营养价值高，具有很好的保健功能，豆制品的销量增加会导致豆制品加工厂的废水量增加，废水处理应该得到重视。

经过对某豆制品加工企业产生的废水水质水量进行综合分析，在查阅国内和国外处理实例的基础上，本设计拟采用“UASB反应器+A2O池”组合工艺对该企业豆制品加工废水进行处理。设计豆制品企业废水处理规模为800m3/d，处理后水质需要达到《污水综合排放标准》（GB8978-1996）一级标准要求。本设计对污水处理的主要构筑物尺寸进行设计计算与选型，对污水处理设备的规格、数量、型号等进行选择分析，完成A2O池工艺图、整体平面布置图、主要污水处理构筑物设计详图以及带高程标注的工艺流程图的绘制。最后，对该设计的总体投资和单位运行成本进行了估算。
