某大学 本科生毕业设计说明书 题 目：包头市某腐乳厂污水处理工艺设计 学生姓名： 学 号： 专 业：环境工程 班 级：环境 指导教师： 包头市某腐乳厂污水处理工艺设计 摘 要 此次毕业设计的题目是包头市某腐乳厂污水处理工艺设计。其主要任务是完成该废水处理设计及单项处理构筑物图纸设计。 其中设计要完成设计计算说明书一份、污水处理厂总平面图一张，高程图一张以及主要构筑物各一张，设备图共七张；单个处理构筑物施工图设计中，主要是完成升流式厌氧污泥床（UASB）、SBR反应池、调节沉淀池、污泥浓缩池平面图和剖面图及部分大样图。 该废水处理工程总规模为4000m3/d。 所选用的污水处理工艺为：废水从进水到格栅，再到调节沉淀池，由污水泵进入集水井，然后进入升流式厌氧污泥床（UASB），再进入SBR反应池，最后排入水体。污泥处理流程为：从升流式厌氧污泥床（UASB）和SBR反应池排出的污泥进入污泥井，通过潜污泵送入浓缩池，然后进入脱水机房，最后外运处置。 废水处理厂处理后的出水要达到国家污水综合排放标准（GB8978—1996）中的二级排放标准。 本设计所选择的UASB+ SBR工艺完全能达到所期望的处理效果。 关键词：升流式厌氧污泥床（UASB）；SBR；腐乳废水。 The design of fermented bean curd factory in Baotou City Abstract The graduation project is the subject of a bean curd factory in BaoTou City sewage treatment process design. Its main task is the completion of the wastewater treatment project design and construction of structures dealing with individual design plans. The design is to complete seven maps ,they are the design specification of a calculation,a sewage treatment plant a total floor plan, an elevation map and the main structures of an equipment map; individual structures dealing with the design of construction plans, mainly to complete up-flow Anaerobic sludge blanket (UASB), SBR tank, regulating sedimentation tanks, sludge thickening pool of floor plans and profiles and some big-like map. the total of the wastewater treatment project is 4000 m3 / d. The wastewater treatment project for the wastewater treatment process is: wastewater from the inlet to the grid, and then to adjust sedimentation tank, submersible pump into the sewage collection wells and then go up-flow anaerobic sludge blanket (UASB), re-entering the SBR reaction, at last,it being discharged into the water body. Sludge treatment process: the sludge from the up-flow anaerobic sludge blanket (UASB) and the SBR tank sludge into the wells, through the submersible pump into the sewage pool enrichment, and then entered the room dehydration, the final disposal of Sinotrans.
