广东20万吨给水厂工艺设计全套图纸附70余页设计说明给水

水厂工艺设计摘要近年来由于农业对地下水的开采，工农业争水矛盾越来越大。另外，城市生产及生活用水量也在逐年增加，且增长速度很快，原有的供水设施在常年负荷下运行也不能满足需要。这种现状已严重影响了城市各行业的发展及居民的正常的生活。为了缓解供水紧张状况，除考虑有效的利用水资源及节约用水以外，必须尽快兴建新的供水设施。考虑到的经济结构调整和持续发展的需要和镇的自然条件（地理位置、地形及气象条件）的特点,进行给水厂设计。选择东江作为水厂的水源。水厂的工艺如下：↓混凝剂↓加氯原水→网格絮凝池、平流沉淀池（合建）→普通快滤池→清水池→二泵站出水设计过程中充分考虑各工艺在实际运行中的应用情况,以及结构的复杂情况等。本设计说明书主要内容包括：设计原始资料，净水厂工艺流程，生产自用水回收工艺，总体布置，建筑物、构筑物设计。关键词：水量絮凝沉淀池普通快滤池水处理工艺AbstractInrecentyears,industrialandagriculturalwateranincreasinglyseriousconflicts，astheexploitationofagricultureongroundwater.Inaddition,productionandurbanwaterconsumptionhasincreasedyearbyyearandthegrowthratesoon,theoriginalwatersupplyfacilitiesintheyearsrunningloadcannotmeettheneed.Thisstateofaffairshasseriouslyaffectedthecitiesofthedevelopmentoftheindustryandtheresidentsofanormallife.Inordertoalleviatethesupplytension,inadditiontoefficientuseofwaterresourcesandwaterconservationmustassoonaspossibletheconstructionofnewwatersupplyfacilities.AccordingthecharacteristicofthenaturalconditionsofandthestonetonetablettownofeconomicrestructuringandsustainabledevelopmentofDongguan(geographicalposition,topographyandmeteorologicalcondition),forthewaterworkstodesign.ChooseDongjiangasthesourceofwaterofthewaterworks.Thecraftofthewaterworksisasfollows:.↓CoagulantRawwater→Gridflocculationpond,rapidfilter↓Chlorination(Jointlybuilt)→Ordinaryquickfiltertank→clearwaterreservoir→twowaterpumpingstationTheprocessofdesigningfullyconsiderallofthepracticaloperationofthesituationandstructureofthecomplexsituation.Thespecificationofthedesignincludingtheoriginaldesigninformation,waterpurification,designofwatermainstructures.Keywords:Storage;Flocculationsedimentationtanks;rapidfilter;Watertreatmenttechnology目录摘要..............................................................................................................................1Abstract........................................................................................................................2第一章设计说明书....................................................................................................71.1总论...................................................................................................................71.1.1项目建设背景.......................................................................................71.1.2编制目的、范围和依据.......................................................................71.1.3工程概况...............................................................................................81.1.4自然条件...............................................................................................81.2总体规划和方案制定.......................................................................................91.2.1水源选择一般原则...............................................................................91.2.2净水厂厂址选择和方案确定.............................................................101.3工程方案内容..................................................................................................101.3.1设计原则............................................................................................101.3.2工程项目规模及内容.........................................................................111.4净水厂构筑物设计说明.................................................................................111.4.1取水构筑物.........................................................................................111.4.2絮凝池.................................................................................................121.4.3平流沉淀池........................................................................................131.4.4普通快滤池.........................................................................................131.4.5清水池.................................................................................................141.4.6送水泵站（二级泵站）.....................................................................141.4.7加氯间.................................................................................................15第二章取水构筑物设计..........................................................................................162.1取水构筑物位置的选择..................................................................................162.2取水构筑物形式的设计..................................................................................172.3集水井设计......................................................................................................172.4一泵站的设计..................................................................................................192.4.1设计流量和扬程的确定.....................................................................192.4.2选择水泵.............................................................................................202.4.3基础尺寸.............................................................................................202.4.4吸水管路和压水管路的计算.............................................................202.4.5水泵安装高度的确定与泵房高度计算.............................................212.4.6辅助设备的确定.................................................................................21第三章净
