兰州交通大学毕业设计（论文）摘要该市区属温带季风型大陆性气候，春季多风干燥，夏季受北太平洋暖流影响，温暖而潮湿，秋季温润凉爽，冬季受蒙古和西伯利亚高气压带控制，寒冷干燥。年平均降水量约550毫米，年平均气温8℃。故使用SBR工艺设计一个东北某市的污水处理厂。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：东北某市；SBR工艺；生活污水；污泥AbstractThecitybelongstothetemperatezonemonsoontypecontinentalclimate,Springiswindyanddry,AffectedbythenorthPacificwarminsummer,Warmandhumid,Coolautumnwarmth,ControlledbyMongoliaandSiberiahighpressurebelt,wintercoldanddry.Averageannualrainfallofabout550mm,Averageannualtemperature8℃.SotheuseofSBRprocessdesignanortheastcitysewagetreatmentplant.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:AcityinnortheastChina;SBRcraft;sanitarysewage;mud兰州交通大学毕业设计（论文）目录TOC\o"1-3"\h\z\uHYPERLINK\l_Toc4321.设计任务及资料PAGEREF_Toc4321HYPERLINK\l_Toc307291.1设计任务
