乳制品废水处理的毕业设计 SHANDONGUNIVERSITY OF TECHNOLOGY Abstract In recent years, Chinas dairy industry has been rapid development, accompanied dairy wastewater pollution problems. The dairy waste water is from the containers, equipment, pipelines, plant, and floor cleaning wastewater, as well as some factory sewage. Characteristics of dairy wastewater showed:1. Water quality and quantity changes over time;2. Concentration of organic pollutants is high and easily biodegradable;3. the biodegradability of the waste water is better. There are many ways to treat dairy wastewater. This design uses the approach of the anaerobic and aerobic. The specific process is as follows: Sewage flows through grille、Sewage upgrade pumping stations、regulation pool、Hydrolysis tank、UASB、CASS;and then discharge sewage into river. The process is flow,good effected, small footprint, and cost savingsThis graduation project include: design and calculation of structures, floor plan layout, elevation layout, project budget, and drawings Key Words:Dairy Wastewater Hydrolysis and Acidification UASB CASS 目 录 摘 要 I Abstract II 目 录 III 第一章 设计说明书 - 1 - 1.1 工程概况 - 1 - 1.2 工艺流程的确定 - 1 - 1.2.2几种处理工艺对比分析 - 1 - 1.2.3.处理构筑物 - 4 - 第二章 设计计算书 - 7 - 2.1.格栅的设计计算 - 7 - 2.1.1确定栅前水深 - 7 - 2.1.2格栅间隙数 - 7 - 2.1.3栅槽总宽度 - 7 - 2.1.4过栅水头损失 - 7 - 2.1.5栅后槽总高度 - 8 - 2.1.6格栅总长度 - 8 - 2.1.7每日栅渣量 - 9 - 2.2 调节池设计计算 - 9 - 2.2.1设计参数 - 9 - 2.2.2有效容积 - 9 - 2.3 水解酸化池 - 9 - 2.3.1水解酸化池的容积: - 9 - 2.3.2配水方式 - 10 - 2.4 UASB反应器设计计算 - 10 - 2.4.1 反应区有效容积 - 10 - 2.4.2 反应器的形状和尺寸 - 10 - 2.4.3 反应器上升流速 - 11 - 2.4.4 UASB反应器进水配水系统设计 - 11 - 2.4.5 三相分离器的构造设计 - 12 - 2.4.6回流缝设计 - 12 - 2.4.7 气液分离设计 - 14 - 2.4.8出水系统设计计算 - 15 - 2.4.9 排泥系统的设计 - 15 - 2.4.10 产气量计算 - 15 - 2.4.11 产泥量计算 - 15 - 2.5 CSAA池设计计算 - 16 - 2.5.1 CASS池容积 - 16 - 2.5.2滗水深度计算 - 17 - 2.5.3联通孔口尺寸 - 17 - 2.5.4 需氧量计算 - 18 - 2.5.5曝气系统布设 - 19 - 2.5.6 剩余污泥量计算 - 19 - 2.6 污泥浓缩池设计计算 - 20 - 2.6.1浓缩池面积 - 20 - 2.6.2浓缩池直径 - 20 - 2.6.3.浓缩池工作部
