内蒙古科技大学毕业设计说明书内蒙古科技大学本科生毕业设计计算说明书题目：呼和浩特市造纸厂废水处理工艺设计学生姓名：钱博学号：0714117525专业：环境工程班级：环境07-5指导教师：郑坤灿内蒙古科技大学毕业设计说明书呼和浩特市造纸厂废水处理工艺设计摘要本次设计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，设备图共五张；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、污水提升泵房、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10000m3/d。所选用的污水处理工艺为：废水从进水到格栅和筛网，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；造纸废水。-I内蒙古科技大学毕业设计说明书IIHohhotpapermillwastewatertreatmentprocessdesignAbstract.Thisdesignmaintaskistocompletethewastewaterprocessingdesignandsingleprocessingstructuresdrawings.Inwhichthedesignmanualtocompleteadesigncalculations,aflowchart,asewagetreatmentplantgenerallayout,elevationplansandthemainstructuresoftheonepieceofequipmentplansatotaloffive;asingletreatmenttankconstructiondesign,themainTocompletetheup-flowanaerobicsludgeblanket(UASB),SBRreactor,adjustingsedimentationtank,sludgethickenerplansandsectionsandsomelargedrawing.Thetotalofthewastewatertreatmentprojectis10000m3/d.Thewastewatertreatmentprojectforthewastewatertreatmentprocessis:wastewaterfromtheinlettothegrid,andthentoadjustsedimentationtank,submersiblepumpintothesewagecollectionwellsandthengoup-flowanaerobicsludgeblanket(UASB),re-enteringtheSBRreaction,atlast,itbeingdischargedintothewaterbody.Sludgetreatmentprocess:thesludgefromtheup-flowanaerobicsludgeblanket(UASB)andtheSBRtanksludgeintothewells,throughthesubmersiblepumpintothesewagepoolenrichment,andthenenteredtheroomdehydration,thefinaldisposalofSinotrans.Wastewatertreatmentplantinthesewageeffluenttoachievecomprehensivenationalemissionstandards(GB8978-1996)ofsecondemissionstandards.ThedesignchosentheUASB+SBRprocessfullytoachievethedesiredeffect.内蒙古科技大学毕业设计说明书IIIKeywords:up-flowanaerobicsludgeblanket(UASB);SBR;Papermakingwastewater.内蒙古科技大学毕业设计说明书IV目录摘要………………………………………………………………………………IAbstract…………………………………………………………………………II第一章绪论………………………………………………………………………11.1概论·······································································································11.2工业废水（IndustrialWastewater）的含义和分类···························11.3工业废水的分类、种类、指标····························································11.3.1分类.............................................................................................11.3.2工业废水造成环境污染的种类....................................................21.4处理原则································································································21.5工业废水处理方法概述········································································31.5.1工业废水的物理处理（PhysicalTreatment）..............................31.5.2工业废水的化学处理（ChemicalTreatment）............................31.5.3工业废水的物理化学处理（Physic-chemicalTreatment）.........31.5.4工业废水的生物处理（BiologicalTreatment）............................41.6现状及发展趋势····················································································41.7设计原始资料························································································71.8设计目的及意义····················································································8第二章：方案的比较与选择………………………………………………………92.1厌氧生物处理工艺的选定·····································································92.2好氧生物处理工艺的选定···································································10内蒙古科技大学毕业设计说明书V2.3工艺流程的确定··················································································11第三章：设计计算…………………………………………………………………133.1格栅计算······························································································133.1.1设计说明....................................................................................133.1.2设计参数....................................................................................153.1.3设计计算....................................................................................153.2筛网的设计说明·················································································183.3配水井设计计算··················································································183.3.1设计说明....................................................................................183.3.2设计计算....................................................................................193.3.3泵位及安装................................................................................203.4提升泵房······························································································203.4.1泵房的设计依据：.....................................................................203.4.2设计说明....................................................................................223.4.3设计计算....................................................................................233.5调节沉淀池··························································································233.5.1设计说明....................................................................................233.5.2设计计算.................................
