[湖南]5万吨净水厂给排水工艺全套图纸(附170页计算说明)VIP免费

X1市给水工程初步设计摘要X1市位于湘南省西部，是一个古老而美丽的城镇，位于溆水中游，近期规划人口12万人，远期发展到20万，市区已建了一座3万m3/d的水厂。随着经济的发展、用水量的增长，现有供水能力已满足不了正常的生产和生活所需。根据城市总体规划，拟在溆水上游建设一新水厂。新水厂建成后，与老厂联合向管网供水，形成统一供水的局面。本设计的主要内容包括：取水构筑物设计；净水厂设计；输配水管网设计；工程概预算四部分。根据城市管网供水的需要，计算得新水厂近期供水规模为5万m3/d，远期为10万m3/d。为保证出水水质，所以新水厂处理工艺采用常规处理＋深度处理（臭氧－生物活性炭），增加深度处理后，能使出厂水水质明显提高。工程建设总投资为9373.65万元,单位制水成本为0.85元/。关键词：取水构筑物，净水厂，常规处理工艺，V型滤池，配水管网，概预算AbstractAsanancientandbeautifulcity,X1cityislocatedinthewestofHunan.OnthemiddlereachesofXuRiver,thecityhasaplanningpopulationof120,000which,inlongterm,willbeexpandedto200,000.Therehasalreadybeena30,000m3/dwaterworksinthedowntownarea.Withthedevelopmentofeconomyandtheincreasingdemandofwater,itscurrentwatersupplyingcapacitycannotmeettherequirementofregularproductionandpeople’sdailylife.Accordingtothecity’scomprehensiveplanning,itisproposedthatanewwaterworksshouldbeconstructedontheupperreachesofXuRiver.Whenitiscompleted,thenewwaterworkswillbejoinedbytheoldonetosupplywatertothepipenetwork,thusmakingastateofunifiedwatersupply.Thisdesignmainlycoversfourpartswhichare:thewaterintakeworks,thepurificationplant,thetubewebsystemofcarryingandprovidingwater,andthebudgetaryestimationofthedesign.Accordingtothedemandofthepipenetwork,itiscalculatedthattheshort-termwatersupplyscaleofthenewwaterworksis50,000m3/dandthelong-termoneis100,000m3/d.Thewatertreatmentprocessofthenewwatertreatmentplantintroducesboththeconventionaltreatmentandtheadvancedtreatmentsoastoremovethehazardoussubstances;Addingadvancedtreatment,thequalityoftheeffluencewillbeimprovedobviously.Thetotalinvestmentofthedesignis93,736,500Yuanandthecostanalysisperunitis0.85Yuan/m3.Keywords：waterintakeworks，purificationplant，routinelyprocessing，V-shapedfilterchamber，waterdistributionnetwork，budgetaryestimation目录1设计原始资料及设计任务.........................................................................................11.1原始资料...........................................................................................................11.1.1自然条件.................................................................................................11.1.2城市概况及供水现状.............................................................................11.1.3供水规划.................................................................................................21.2设计目的和要求...............................................................................................21.2.1设计目的.................................................................................................21.2.2设计要求.................................................................................................31.3设计范围...........................................................................................................31.4设计依据...........................................................................................................42设计水量计算...............................................................................................
