内蒙古科技大学毕业论文包头市北郊污水厂污水资源化利用可行性研究摘要本论文通过分析国内外城市污水回用现状及存在问题，针对包头市水资源严重短缺和污水再利用的情况，寻求解决污水资源化利用的有效途径。根据包头市水资源规划情况，调研了包头市北郊污水厂二级出水水质及主要用户的水质要求，通过对深度处理技术的比较选择，结合包头市冬季时间长、气温低的特点，确定北郊污水资源化利用的工艺方案为：絮凝—沉淀—过滤。在确定个构筑物尺寸及工艺参数后，对该方案进行环境、社会和经济效益的分析及经济评价，证明该方案具有可行性。经静态投资估算及经济评价后可得出结论：在销售水价为1.0元/吨的基础上，处理水量达到设计水量的29.5%后即可实现收益，即该方案具有较好的经济效益。关键词：污水资源化可行性研究V型滤池经济评价I内蒙古科技大学毕业论文FeasibilityStudyForReuseofBaotouBeijiaoWastewaterTreatmentPlantEffluentAbstractByanalyzingtherecyclingstateofsewageandproblemshomeandabroad,thisthesisseeksaeffectivewaytomakethereuseofreclaimedwatercometrue,onaccountofthesevershortageofwaterresourceinBaotou.AccordingtothestrategiesofwaterresourceinBaotou,thisthesissurveysthequalityofeffluentofBeijiaoWasteWaterTreatmentPlantandthequalityofwaterrequirementofthemainsubscribers.BycomparingthetechnologyofTertiaryTreatment,confirmingthetechnologyofthereclamationofsewageinBeijiaoWasteWaterTreatmentPlantis:flocculation—sedimentation—filtration,basedonthelong-winter,low-temperaturecharacterofBaotou.Indeterminethesizesandprocessparametersofthesestructures,theenvironmentalandsocialassessment,economicevaluationtellusthat:theprojectisfeasible.Aftertheestimationofstaticinvestmentandeconomicevaluation,wecangettheconclusion:Basedonthesalespriceof1.0yuan/t,thewateramounttreatedgetto95%ofthedesignvalue,gainscanberealized.Sotheprojecthasgoodeconomicbenefits.Keywords:ReclamationofSewageFeasibilityStudyV-FilterEconomicEvaluationII内蒙古科技大学毕业论文目录摘要....................................................................................................................................IAbstract................................................................................................................................II目录.................................................................................................................................III第一章绪论..........................................................................................................................1第二章再生水回用的可行性..............................................................................................32.1我国的水污染现状...................................................................................................32.2污水排放量...............................................................................................................32.3水质污染状况...........................................................................................................32.4国内外城市再生水利用简介...................................................................................42.4.1国外城市再生水利用简述.............................................................................42.4.2国内城市再生水利用简述.............................................................................62.4.3我国中水回用技术的发展及现状.................................................................72.5包头市再生水利用的前景...................................................
