给排水毕业设计说明书

河北联合大学毕业设计说明书I摘要本设计的主要任务是唐山市丰润区给水工程初步设计。设计的主要内容包括：给水方案比较、净水厂设计。设计书由设计资料、设计说明书和设计计算书三部分组成。本设计的一期设计规模是12.0万m3/d，以水库水为水源。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、处理构筑物的设计计算以及水厂的平面和高程布置。水厂出水水质要求达到《生活饮用水卫生规范》（2001）。水厂位于该区北部，地面标高为14.20m，，绿化面积约占25％，附属面积约占总面积的15％，内设标准化篮球场和排球场，力争创建一个清新怡人的现代化水厂。关键词净水工程；机械搅拌澄清池；普通快滤池；清水池，河北联合大学毕业设计说明书IIABSTRACTThemaintaskofthisdesignisinfengrunquinTangsanCity,thepreliminarydesignofthecountywatersupplyproject.Thekeyelementsofdesign:watersupplyschemes,watertreatmentplantdesign.Waterdistributionnetworkwiththecalculationandadjustment.Designinformationfromdesigndocuments,designspecificationanddesignofthebookiscomposedofthreepartscalculation.Thisdesignisthesizeoftherecentdesignof120,000m3/d,forthewatertolakewater.Thesurfacewaterdiversionprojectconsistsoftheselectionofwatersourcelocation,theformofwaterdiversionandthedesignofpumpstation.Andsodoesthegroundwaterdiversionproject.Waterplanttomeetwaterqualityrequirements,DrinkingWaterHealthStandards(2001).WenCountyWaterTreatmentPlantislocatedinsuburbancounties,northofthecity,thegroundelevationis14.20m,accountingforabout25%greenarea,subareaofabout15%ofthetotalarea,willincludethestandardizationofthebasketballcourtandvolleyballcourt,andstrivetocreateamodernandpleasantfreshwaterplant.Keywordswatertreatmentproject;mechanicalstirring;highspeedfiltercellClearancepond河北联合大学毕业设计说明书I目录第一章绪论......................................................-1-1.1设计资料介绍..............................................-1-1.1.1任务依据：..........................................-1-1.1.2设计资料：..........................................-1-1.1.3设计范围：..............................错误!未定义书签。1.1.4设计要求：..............................错误!未定义书签。1.1.5毕业设计成果要求：......................错误!未定义书签。1.2各个构筑物工艺概况........................................-3-1.2.1混合工艺............................................-3-1.2.2絮凝过程............................................-3-1.2.3沉淀过程............................................-3-1.2.4过滤过程............................................-3-1.2.5吸附过程............................................-4-1.2.6清水输送过程........................................-4-1.3方案比较与设计计算........................................-4-第二章给水厂设计方案论证........................................-5-2.1方案比较原则..............................................-5-2.2处理工艺流程选择..........................................-5-2.2.1混合设备............................................-7-2.2.2反应絮凝池..........................................-8-2.2.3沉淀池..............................................-8-2.2.4滤池................................................-9-2.2.5吸附池.............................................-10-第三章净水厂构筑物设计计算.....................................-12-3.1设计水量的确定...........................................-12-3.2配水井设计计算...........................................-12-3.3加药及混合反应设计计算...................................-12-河北联合大学毕业设计说明书II3.3.1混凝剂的选择和投加.................................-12-3.3.2投药系统布置.......................................-14-3.3.3混合工艺设计计算...................................-17-3.4絮凝反应设计计算.........................................-20-3.4.1絮凝工艺设计计算...................................-21-3.4.2絮凝池排泥.........................................-25-3.5沉淀池设计计算...........................................-25-3.5.1沉淀设施的设计.....................................-25-3.5.2污泥处理构筑物设计.................................-31-3.6滤池设计计算.............................................-37-3.6.1设计参数...........................................-38-3.6.2滤池的设计与计算...................................-38-3.7活性炭吸附池设计计算.....................................-46-3.7.1设计参数...........................................-47-3.7.2吸附池的设计与计算.................................-47-3.8消毒设计计算.............................................-54-3.8.1液氯的消毒原理.....................................-56-3.8.2加氯量计算.........................................-56-3.8.3加氯设备...........................................-57-3.8.4加氯间的布置.......................................-57-3.8.5液氯仓库...........................................-58-3.8.6液氯储备..........................................-58-3.8.7氯库占地面积......................................-59-3.9清水池设计计算...........................................-59-3.9.1清水池有效容积....................................-59-3.9.2清水池尺寸........................................-60-3.9.3管道布置..........................................-60-3.9.4吸水井布置.........................................-61-第四章水厂平面及高程布置.......................................-63-河北联合大学毕业设计说明书III4.1水厂的平面布置...........................................-63-4.1.1水厂平面布置主要内容...............................-63-4.1.2水厂平面布置要求...................................-63-4.2水厂的高程布置...........................................-64-4.2.1净水构筑物水头损失.................................-64-4.2.2各构筑物连接管线的水头损失.........................-65-4.2.3各构筑物标高计算...................................-65-参考文献........................................................-67-致谢..........................................................-71-附录............................................................-72
