成都理工大学中水工程方案设计作者姓名:邵俊学号:200303020106专业:环境工程(水污染控制方向)指导教师:刘清华【摘要】本设计以成都理工大学生活污水为主要水源,设计中水回用系统的主要处理流程。在采样分析和估算水量的基础上,比较了现有的多种中水回用工艺,最终确定了以膜生物反应器(MBR)为主要处理工艺的中水处理流程。通过计算确定了工艺流程中主要设施的尺寸以及设备的型号。计算分析表明,设计处理出水水质达到且优于国家相关标准。通过对设施运行成本的估算证明,该流程在处理成本上有实施的可能。【关键词】污水;中水;中水系统;膜生物反应器DesignoftheengineeringprojectforReclaimedWaterSystemofChengduUniversityofTechnologyName:JunShaoStudentNo.:200303020106Major:EnvironmentalEngineering(Waterpollutioncontrol)Supervisor:LiuQinghuaAbstract:Amaintreatmentflowofthereclaimedwatersystemwillbedesignedinthisdissertation.Thereclaimedwatersystemselectsthewastewaterflew-downfromthedormitoriesofChengduUniversityofTechnologyasraw-waterofreclaimedwater.Afteranalysingtherawwaterandinvestigatingthewastewater-producting,atreatmentflowhasbeendesignedbasedoncomparingcurrentreclaimedwatertreatmentmethods.Theflowdesignedchoosesthemembranebioreactor(MBR)asthemaintreatmenttechnology.Thearticledesignsandcalculatestheparametersaboutthestructuresandtheequipmentsinthetreatment.TheresultsofcalculationsandanalysisonReclaimedWatertreatmenttechnologyindicatesthatthetreatedwatercanachievetherelevantstandards.Byanalyzingthehandlingcosts,itisprovedthatthetreatmentflowislogicalandalsopossibletobeputinpracticed.Keywords:Wastewater;Reclaimedwater;Reclaimedwatersystem;Membranebioreactor成都理工大学毕业设计i目录第1章前言..............................................................................................................11.1本课题的选题背景........................................................................................11.2本课题的意义................................................................................................11.3本人工作量....................................................................................................1第2章中水概述..........................................................................................................22.1中水概念.......................................................................................................22.2中水用途.......................................................................................................22.3中水系统组成...............................................................................................22.4中水的水质要求............................................................................................32.5中水回用情况...............................................................................................32.5.1国外中水回用情况................................................................................32.5.2我国中水回用情况................................................................................3第3章设计项目概述..................................................................................................53.1成都理工大学校园生活污水处理现状.......................................................53.2设计项目中水水源........................................................................................53.3中水处理目标及标准...................................................................................53.4设计依据.......................................................................................................53.5设计原则.......................................................................................................63.6设计范围.......................................................................................................6第4章方案选择及论证..............................................................................................84.1中水回用处理的基本方法............................................................................84.2中水回用处理工艺概述................................................................................84.1.1以优质杂排水为原水的中水工艺..................................................84.1.2以生活污水为原水的中水工艺....................................................114.3方案比较.....................................................................................................144.4方案论证.....................................................................................................15第5章设计计算........................................................................................................175.1原水水质.....................................................................................................175.2水量计算.....................................................................................................175.2.1回用水需求量.................................................................................185.2.2水量校核........................................................................................19成都理工大学毕业设计ii5.3构筑物设计计算.........................................................................................195.3.1格栅设计计算................................................................................195.3.2调节池设计计算............................................................................225.3.3沉砂池设计计算............................................................................235.3.4膜生物(MBR)反应池设计计算................................................245.3.5消毒池设计计算................................................................
