荣成市污水处理厂初步设计摘要荣成市地处山东半岛最东端，三面环海，海岸线长500公里。拥有石岛、龙眼两个一类开放口岸，山东省GDP排名第一的县级市（威海市代管），中国魅力城市，优秀旅游城市，生态园林城市，人居范例城市，环保模范城市，新兴工业强市，沿海开放城市，海洋经济大市，国家级海洋食品名城，人口较多。所以使用SBR工艺设计一个荣成市的污水处理厂。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态生化反应，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：荣成市；SBR工艺；生活污水；污泥City25,000m3/dsanitarysewageSBRofRongchengdealswithtechnologicaldesignAbstractRongchengislocatedintheeasterntipofShandongPeninsula,surroundedbythesea,acoastlineof500km.RongchenghasShidao,longanwhichareone-classopenport,anditisthefirstcounty-levelcityGDPrankings(WeihaiCityhosted)inShandongProvince.ItwasHewasknownastheChinesecharmofthecity,excellenttouristcity,eco-gardencity,livingexamplescities,environmentalprotectionmodelcity,theemergingstrongcity,coastalopencities,theGreatCityNationalOceanmarinefoodcity.However,ithaslagerpopulation.SousetheSBRprocessdesignofasewagetreatmentplantinRongcheng.SBRistheabbreviationoftheintermittencetypeactivemudlaw(SequencingBatchReactorActivatedSludgeProcess)ofthearray,itisonekindthatexposestothesuntheactivemudsewagetreatmenttechnologythattheangrywayoperatesaccordingtotheintermittence,alsocalledthecriticizingtypelawofactivemudofpreface.Differentfromtraditionalsewagedisposalcraft,SBRtechnologyadoptoperationmodethattimecutapartsubstituteoperationmodethatspacecutapart,stabilizebiochemistryisitsubstitutestablestatebiochemistryreact,quiettoputidealprecipitateandsubstitutethetraditionaldynamicsedimenttoreact.Onmaincharacteristicofitoperateinorderandintermittenceoperate,core,SBRoftechnologythatSBRreactsinthepool,thispoolcollectsmelting,sinkingforthefirsttime,functionthatbiodegradation,twosink,etc.inonepond,thereisnomudbacksetcurrentsystem.Canreachthedesigningrequirementthroughthewastewaterofthiswastewatertreatmentcraft,candischargedirectly.Mudthatproduceafterconcentrating,pressingandstrainingetc.dealingwith,gooncompostproducesureeconomicbenefits.Keywords:Rongcheng；SBRcraft；sanitarysewage；mud0引言.................................................................11概述.................................................................21.1设计任务和依据.................................................21.1.1设计任务..................................................21.1.2设计依据..................................................21.2设计要求......................................................21.2.1污水处理厂设计原则........................................21.2.2污水处理工程运行过程中应遵循的原则........................31.3原始数据........................................................31.4荣成市城市环境条件概况..........................................41.4.1地理位置..................................................41.4.2气象水文..................................................42工艺比较分析.........................................................53设计计算.............................................................83.1原始设计参数...................................................83.2中格栅.........................................................83.2.1设计说明..................................................83.2.2设计参数..................................................83.3污水提升泵房和集水井...........................................113.3.1提升泵...................................................113.3.2集水井...................................................113.5沉砂池........................................................143.5.1设计说明.................................................143.5.2设计参数.................................................143.5.3设计计算.................................................143.6配水井设计.....................................................163.6.1配水井设计要求...........................................163.6.2配水井设计计算...........................................173.7SBR反应池.....................................................183.7.1设计说明.................................................183.7.2SBR反应池容积计算.......................................203.7.3SBR反应池运行时间与水位控制.............................213.7.4排水口高度和排水管管径...................................223.7.5排泥量及排泥系统.........................................223.7.6需氧量及曝气系统设计计算.................................233.7.7空气管计算...............................................253.7.8滗水器...................................................263.8鼓风机房.......................................................263.9接触消毒池.....................................................273.9.1设计说明.................................................273.9.2设计参数.................................................283.9.3设计计算.................................................283.10污泥处理系统的设计............................................293.10.1污泥水分去除的意义和方法................................293.10.2产泥量..................................................293.10.3集泥井..................................................304污水处理站平面布置和高程布置........................................314.1污水处理厂平面布置............................................
