给水工程毕业设计说明书

广州大学毕业设计I摘要本次设计为广东新华地区给水工程初步设计，设计内容主要包括三个部分，即取水工程、给水管网设计和净水厂设计。根据设计资料，取水构筑物采用岸边合建式取水构筑物，给水管网设计经过技术经济比较采用统一供水方案，净水厂处理工艺采用常规处理+深度处理，即“混凝-沉淀-过滤-臭氧氧化-活性炭吸附-消毒”。混凝包括混合和絮凝两部分。混合是在静态混合器投加聚合氯化铝，絮凝采用网格絮凝池，选用平流沉淀池进行沉淀，过滤设备采用均质滤料滤池，臭氧氧化选用臭氧接触池，再通过活性炭滤池，最后投加液氯进行消毒。经过净水厂中各构筑物处理后，出厂水达到优质饮用水要求。关键词取水工程；给水管网；净水厂；常规处理；深度处理ABSTRACTThisdesignisthewatersupplypreliminarydesignofXinhuaGuangdongprovince.Itmainlyincludesthreeparts:theintakeworks,thewaterpipenetworkdesignandthewatertreatmentplantdesign.Accordingtothedesigninformation,takesthewaterconstructiontousetheshoretobuildthetypetotakethewaterconstruction,theservicepipenetdesignusestheunificationwatersupplyplanafterthetechnicaleconomycomparison,thewaterpurificationfactoryprocessingcraftusestheconventionalprocessing+advancedtreatment,namelyflocculation-sedimentation-filtration-Ozoneoxide-activatedcarbonadsorption–disinfection.Coagulationincludingmixandflocculationtwoparts.Themixisthrowsinthestaticmixercongenialpolymerizationaluminumchloride,theflocculationusesthegridflocculationpond,selectstheadvectionsedimentationpondtocarryontheprecipitation,thefilterplantusesisotropicfiltersthematerialfiltertank,theozoneoxidationselectstheozonecontactpond,throughtheactivatedcharcoalfiltertank,throwsfinallyagainaddstheliquidchlorinetocarryonthedisinfection.Afterwaterpurificationfactoryinvariousconstructionsprocessing,theleavingtheplantwatermeetsthehighqualitytapwaterrequirements.KEYWORDSintakework;waterpipenetwork;watertreatmentplant;conventionalprocessing;advancedtreatment广州大学毕业设计II目录前言........................................................................................................................................................1第一章绪论............................................................................................................................................21.1原始资料...................................................................................................................................2第二章给水管网方案设计与计算.........................................................................................................42.1管网定线...................................................................................................................................42.2用水量计算...............................................................................................................................62.2.1统一供水用水量计算....................................................................................................62.2.2分区供水用水量计算....................................................................................................72.3管网水力计算............................................................................................................................92.3.1统一供水水力计算........................................................................................................92.3.2分区供水水力计算......................................................................................................132.4管网平差.................................................................................................................................182.4.1统一供水管网平差......................................................................................................182.4.1分区供水管网平差......................................................................................................20第三章方案经济技术比较...................................................................................................................223.1经济比较.................................................................................................................................223.1.1统一供水方案管网造价..............................................................................................223.1.2分区供水方案管网造价..............................................................................................223.2技术比较.................................................................................................................................233.3确定方案.................................................................................................................................23第四章净水厂的设计...........................................................................................错误！未定义书签。4.1工艺流程确定..........................................................................................错误！未定义书签。4.2处理构筑物及设备型式选择..................................................................错误！未定义书签。4.2.1混凝剂的选择..............................................................................错误！未定义书签。4.2.2混凝投加方式的选择.................................................................错误！未定义书签。4.2.3絮凝设备......................................................................................错误！未定义书签。4.2.4沉淀池..........................................................................................错误！未定义书签。4.2.5滤池.............................................................................................错误！未定义书签。4.2.6消毒.....................................................................................
