某小区生活污水中水回用处理工程设计中北大学分校毕业设计---PAGEIII-摘要目前由于需水量激增以及水资源的浪费和污染，水资源短缺的危机很严重。设置中水回用可以有效地利用和节约淡水资源，减少污、废水排放量，减少水环境污染。在结合某生活小区基本资料，认真分析小区所排放的污水现状的基础上，明确了建设中水处理回用站的必要性。根据项目设计要求，经过对当前多种常见中水处理回用工艺的分析对比后得出选择结果，提出了应用CASS工艺处理污水的方案，重点阐述了CASS工艺原理及处理生活污水并回用的工艺流程。为使污水中主要参数达标以实现小区污水再生利用，对包括格栅、调节池、潜污泵、CASS池、快滤池、加药消毒及贮水池等具体的工艺设计部分进行了详细计算。按照设计原则与规范完成污水处理站的总平面布置及高程布置，参考相关资料对处理站进行了人员编排及运行成本分析，并就安全生产等问题制定说明。根据设计结果完成工程制图，对该处理站工程的施工建造提供了明确的图纸依据。关键词：生活污水；中水回用；CASS工艺；消毒ACommunityLivingInSewageWaterTreatmentProjectDesignedToUseAbstractContaminateatpresentsincethewaterrequirementincreasessharplybyandthewaterresourcedissipationdraws,waterresourceshortagecrisisisverygrave.Setupmiddlewaterusingtimebeingabletomakeuseoffreshwaterresourcesandsaveeffectively,cutdownthefilth,wastewaterdischargingamounts,cutdownwaterenvironmentalpollution.Housingestatefundamentaldatainlivingcombiningwithsome,havemadeclearthatwatertreatmentreturnstothenecessityusingastationinconstructiononthebasisanalysingfoulwatercurrentsituationdischargedbyhousingestatecarefully.Accordingtoprojectdesigndemand,thequeenreachestheresultchoosingbythatwatertreatmentreturnstotheanalysiscontrastusinghandicrafttocurrentlyvariouscommonmiddle,schemehavingsuggestedthatthehandicraftapplyingCASSdisposesofsewage,priorityhassetforthCASShandicraftprincipleandtheprocessflowhandlingadomesticsewageandusingtime.Havewaitedfortheconcreteprocessdesignparttobeinprogressforthemainparameterreachesthestandardtorealizehousingestatefoulwaterregeneratingthedegassingandpondforstoringwatermakinguseofmedicine,addingtothefilthpump,CASSpool,quickfilterchamberincludingagrille,adjustingpool,sneakingintoinusingfoulwater,detailedsecretlyschemeagainst.Generalflatsurfacearrangementandelevationarrangementstandingaccordingtothatdesignphilosophyandthenormaccomplishsewagetreatment,thepersonnelthereferencerelevancedatahasbeencarriedoutontohandlingastationarrangesandrunscostanalysis,andsafetyatworkwaitsforaproblemtoworkoutexplanationrightaway.Accordingtotheeng
