某小区日生活污水处理工艺设计

专利私有，盗版必究！摘要城市污水包括生活污水、工业污水两种。城市污水的性质特征与人们的生活习惯；环境气候条件；生活污水与工业污水所占比例；所采用的排水体制以及国家、地方部门对水质的要求等方面有关。城市污水排放至下水道时要满足《污水排入城市下水道水质标准》（CJ3082-1999），排放到水体时要满足《污水综合排放标准》（GB8978-96）。本文主要是对某小区3000m3/d生活污水采用SBR工艺进行处理并回用。SBR是序列间歇式活性污泥法（SequencingBatchReactorActivatedSludgeProcess）的简称，是一种按间歇曝气方式来运行的活性污泥污水处理技术，又称序批式活性污泥法。SBR与传统污水处理工艺不同，SBR技术采用时间分割的操作方式替代空间分割的操作方式，非稳定生化反应替代稳定生化反应，静置理想沉淀替代传统的动态沉淀。它的主要特征是在运行上的有序和间歇操作，SBR技术的核心是SBR反应池，该池集均化、初沉、生物降解、二沉等功能于一池，无污泥回流系统。经过这个废水处理工艺的废水可达到设计要求，可以直接排放。产生的污泥经过浓缩、压滤等处理后，进行堆肥产生一定的经济效益。关键词：城市污水；SBR工艺；传统污水处理工艺专利私有，盗版必究！AbstractCitysewageincludingsanitarysewage,industrialsewagetwokinds.Citysewagenaturecharacteristicandpeople'shabitsandcustoms;Environmentclimaticconditions;Thesanitarysewageandthesanitarysewageaccountfortheproportion;Usesthedrainingwatersystemaswellasnational,aspectsandsoonplacedepartmentaddingwaterarcherytargetrequestconcern.CitysewageemissionstosewerwhenmustsatisfySewageTodisperseintoCitySewerWaterqualityStandard(CJ3082-1999),dischargeswhenthewaterbodymustsatisfySewageSynthesisEmissionsStandard(GB8978-96).ThisarticlemainlyisusetheSBRcrafttosomeplot3000m3/dsanitarysewagetocarryonprocessingandthesalescommission.SBRisthesequenceintermittencetypeactivesludgelaw(SequencingBatchReactorActivatedSludgeProcess)theabbreviation,isonekindtheactivesludgesewagetreatmenttechnologywhichmovesaccordingtotheintermittentaerationway,alsocalledtheforewordapprovesthetypeactivesludgelaw.SBRandthetraditionsewagetreatmentcraftisdifferent,theSBRtechnologyusesthetimedivisiontheoperatingmodesubstitutionspacedivisionoperatingmode,decidesthebiochemistrytorespondunstablethesubstitutionstablestatebiochemistryresponded,settlementidealprecipitationsubstitutiontraditiondynamicprecipitation.Itsmaincharacteristicisinthemovementorderandthebatchoperation,theSBRtechnologycoreistheSBRresponsepond,thiscollectionequalization,initiallysinks,thebiodegradation,twosinksandsoonthefunctionsinone,non-sludgerecirculatingsystem.Afterthiswastewaterprocessingcraftwastewatermayachievethedesignrequest,maydischargedirectly.Producesthesludgeafterprocessingandsoonconcentration,filterpressing,carriesonthecomposttohavecertaineconomicefficiency.Keywords:Citysewage;SBRcraft;Traditionsewagetreatmentcraft专利私有，盗版必究！目录前言..................................................................1第一章城市污水处理....................................................31.1城市污水概述....................................................31.2污水分类........................................................31.3污水处理程度的划分及处理方法....................................31.3.1处理程度的划分............................................31.3.2常用污水处理方法..........................................41.4我国城市污水处理现状............................................51.5我国污水处理存在的问题..........................................51.6我国污水处理今后发展趋势........................................6第二章序批式活性污泥法（SBR）工艺.....................................92.1SBR工艺简介....................................................92.2SBR工艺设计的特点..............................................92.3SBR工艺的适用范围.............................................102.4工艺选择原则...................................................102.5活性污泥的性能及其评价指标.....................................102.6SBR工艺的流程.................................................11第三章污水处理构筑物的设计计算.......................................123.1原始设计参数...................................................123.2格栅...........................................................123.2.1设计说明.................................................123.2.2设计参数.................................................133.2.3设计计算.................................................133.2.4常用格栅.................................................153.3一级提升泵的设计...............................................163.4调节池的设计...................................................183.4.1设计说明.................................................183.4.2设计计算.................................................18专利私有，盗版必究！3.5曝气沉砂池.....................................................193.5.1设计说明.................................................193.5.2设计参数.................................................193.5.3设计计算.................................................203.6SBR反应池.....................................................233.6.1设计说明.................................................233.6.2设计计算.................................................243.6.3SBR反应池运行时间与水位控制..............................263.6.4排水口高度和排水管管径...................................263.6.5排泥量及排泥系统.........................................263.6.6需氧量及曝气系统设计计算.................................273.6.7空气管计算...............................................303.6.8滗水器...................................................303.7鼓风机房.......................................................31第四章污泥处理系统...................................................324.1污泥水分去除的意义和方法.......................................324.2各部分尺寸计算.................................................324.3污泥浓缩池.....................................................334.4污泥脱水池..............
