给排水专业毕业设计

摘要I摘要按照教学任务，本学期是大四学生进行毕业实习和毕业设计的时间，其中毕业设计是本科四年学习计划的最后一个重要的实践性学习环节，是对前期所学基础理论、基本技能及专业知识的综合应用。通过毕业设计，让同学们在即将走向工作岗位前进行最后一次模拟演练，培养学生们的积极性和主动性，以及解决实际问题的能力，提高自己的查阅资料和绘图能力，进一步巩固大学期间所学的专业知识，增强同学们的合作意识和创新意识，为同学们即将从事专业工作奠定基础。因此，做好本次毕业设计就显得相当重要，所以我们每位同学都应怀着积极认真的态度来对待这次毕业设计。给水工程设计，一般包括取水工程，二泵站设计，水厂设计以及管道工程的设计，是给排水的重要组成部分。本工程是华南地区湖南省衡阳市给水工程设计，供水规模是10万吨每天，衡阳市在全国属于特大城市，各用水户对水质没有特别要求。其中取水工程为地表水取水工程.地表水取水工程的设计内容包括地表取水位置的选择,取水形式的确定及取水泵站的设计计算。输配水工程主要包括管网的定线和管网的水力平衡计算。净水厂的设计是指净水厂的位置选择，水处理工艺流程的确定，水处理构筑物的设计计算，送水泵站的设计以及水厂的平面和高程布置。通过本次毕业设计将自己课堂上所学的知识进一步系统化，培养自己独立思考的能力，提高自己对专业软件的使用能力，以及查阅资料，解决问题的能力。同学们应积极配合老师，独立按时完成老师要求的任务，认真阅读设计规范，努力认真的做好相关图纸的绘制。关键词：毕业设计、衡阳市、给水工程、净水工艺、泵站河南城建学院本科毕业设计摘要IISummaryAccordingtotheteachingtask,isaseniorstudentthissemesterforgraduationpracticeandgraduationdesign,thegraduationdesignisthelastfouryearsofundergraduatestudyplanimportantpracticallearninglink,istoearlytowhattheyhavelearnedthebasictheory,basicskillsandprofessionalknowledgeofcomprehensiveapplication.Throughthegraduationdesign,lettheclassmatesbeforecomingtoworkforthelasttimesimulationexercises,tocultivatethestudents'enthusiasmandinitiative,aswellastheabilitytosolvepracticalproblems,toimprovetheiraccesstoinformationanddrawingability,furtherconsolidatewhattheyhavelearnedduringtheperiodofuniversityprofessionalknowledge,enhancestudents'cooperationconsciousnessandinnovationconsciousness,andlaythefoundationforstudentstoengageinprofessionalwork.So,dothegraduationdesignisquiteimportant,soweeveryoneshouldbetreatedwithapositiveandseriousattitudetothegraduationdesign.Watersupplyengineeringdesign,generallyincludingwaterengineering,2pumpstationdesign,plantdesignandthedesignofpipelineengineering,isanimportantpartofwatersupplyanddrainage.ThisprojectisthehengyangcityofhunanprovinceinsouthChina,watersupplyengineeringdesignscaleofwatersupplyis100000tonseveryday,hengyangbelongstomegacitiesacrossthecountry,allthewateronwaterqualityandnospecialrequirements.Ofwhichobtainingwaterengineeringforsurfacewater.Surfacewaterintakeengineeringdesigncontentincludesthesurfaceofwaterintakelocationselection,thedeterminationofwaterform,andthecalculationinthedesignofwaterintakepumpstation.ShuPeiShuiengineeringmainlyincludenetworkrouting,andpipenetworkhydraulicbalancecalculation.河南城建学院本科毕业设计摘要IIITreatmentofwatertreatmentworksdesignreferstothelocationselection,thedeterminationofwatertreatmentprocessflow,designcalculationforwatertreatmentstructures,waterpumpingstationdesignandwaterworksplaneandelevationarrangement.Throughthegraduationdesignwillleadtoafurthersystematicknowledgetheylearnedinclass,cultivatetheirindependentthinkingability,improvemyself'sabilitytouseprofessionalsoftware,anddataaccess,theabilitytosolvetheproblem.Studentsshouldactivelycooperatewiththeteacher,independentontimecompletethetasktheteacherasked,readdesignspecifications,effortearnestcompletestherelateddrawingsofthedraw.Keywords:thegraduationdesign,hengyang,watersupplyengineering,waterpurificationprocess,thepumpstation河南城建学院本科毕业设计摘要IV河南城建学院本科毕业设计目录V目录摘要Summary前言..............................................................................................................................-1-第一章水量及给水管网设计计算..........................................................................-7-1.1用水量计算...................................................................................................-7-1.2管网水力计算...........................................................................................-12-第二章阀门及管道附件......................................................................................-32-2.1阀类...........................................................................................................-32-2.2管道附件...................................................................................................-32-第三章净水厂设计................................................................................................-33-3.1设计资料及设计原则..................................................................................-33-3.1.1设计基础资料..................................................................................-33-3.1.2设计原则..........................................................................................-34-3.2总体设计.....................................................................................................-35-3.2.1水厂规模的确定............................................................................-35-3.2.2净水工艺流程的确定......................................................................-35-3.2.3处理构筑物及设备型式选择..........................................................-36-3.3加药设施的设计计算.................................................................................-38-3.3.1混凝剂投配设备的设计..................................................................-38-3.3.2溶液池的计算..................................................................................-39-3.3.3溶解池的计算..................................................................................-39-3.3.4投药管的计算..........................................................................
