I摘要我国是一个极其缺水的国家，国家出台了许多政策，要求生产节水产品，并要求增强居民节水意识。在国家大力号召下，许多生产厂家下大力度研发节水产品，来满足人们的需要，给人们带来更多的收益，节水产品在家庭生活中取得了良好的效果，人们从一系列的变化数字中领悟到节水减少了部分生活开支。实际生活中，我们有部分水是可以在再利用的。本设计基于中水回用的相关技术，通过集水箱收集家庭废水并进行简单处理，再输送至蓄水箱，最终用于厕所冲水、家庭浇花拖地以及厨房消防。该设计主要解决家庭废水回收利用的问题，意义旨在节约家庭用水，提高水的回收利用率，为环保节能献力。关键词：家庭废水回收利用IIAbstractOurcountryisaextremelywater-shortcountry.Thecountryhasissuedamanypolicies,callingontheproductionwatersavingproductrequirements,andenhancingresidentswatersavingconsciousness.Incountriesunderthecallvigorously,manymanufacturersofwatersupplyproductsresearchanddevelopment,tomeettheneedsofthepeople,givepeoplemoreearnings.Watersavingproductsinfamilylifehasobtainedgoodeffect.Peoplefromaseriesofchangesinthenumberofwatersavingawakentoreducethecostsofliving.Inreallife,wehavepartofthewatercanbeinrecycled.Thisdesignbasedonthewaterreuserelatedtechnology,throughthecollectionofwatertankcollectionandsimplefamilywastewatertreatmentandthentransportedtothewaterstoragebox,eventuallyusedintoilet,familywateringtheflowers，moppingthefloorandkitchenfire.Thisdesignismainlytosolvetheproblemofwastewaterrecyclingfamily,meaningthefamilytosavewaterandimprovewaterrecycling,environmentalprotectionandenergysavingfortheirpower.Keywords:FamilywastewaterRecyclingIII目录第一章绪论.................................................................................................................11.1设计背景...........................................................................................................11.2家庭废水情况...................................................................................................11.2.1家庭废水统计.........................................................................................11.2.2家庭废水特点.........................................................................................21.2.3家庭污废水的分类.................................................................................21.2.4家庭废水的处理要求.............................................................................21.3家庭废水的处理...............................................................................................31.3.1中水回用的概念.....................................................................................31.3.2中水水质要求.........................................................................................31.3.3中水的分类.............................................................................................31.3.4中水处理方法.........................................................................................41.4家庭废水处理中存在的问题...........................................................................51.5中水回用技术的现状与发展...........................................................................51.6本文主要研究内容及各章节安排...................................................................6第二章家庭废水回收利用装置的总体设计说明.......................................................82.1总体设计方案及定位.......................................................................................82.1.1家庭废水水质标准.................................................................................82.1.2中水回用水质标准.................................................................................92.2装置设计方技术比较与选择.........................................................................102.3家庭废水回收利用装置外观及内部详细图解.............................................112.4本章小结.........................................................................................................15第三章小型饮用水应急处理装置各类材料的选择及介绍.....................................163.1家庭废水回收利用装置材料的选择.............................................................163.1.1砂滤料的选择.......................................................................................163.1.2除油材料的选择...................................................................................163.1.3活性炭的选择.......................................................................................173.1.4活性炭应用的安全问题.......................................................................183.1.5装置结构材料的选择.......................................................................183.1.6装置管材的选择...................................................................................183.1.7液位继电器的选择...............................................................................193.2家庭废水回收利用装置详解.........................................................................193.3本章小结.........................................................................................................23第四章家庭废水回收利用装置计算书.....................................................................244.1装置尺寸的设计计算.....................................................................................244.1.1集水箱（处理箱）部分.......................................................................244.1.2提升水泵选择.......................................................................................254.1.3蓄水箱部分...........................................................................................254.1.4消防泵的选择.......................................................................................264.1.5管径的选择................
