UASB王 夙1, 张利群2, 吴 敏1, 杨 健1(1.同济大学环境科学与工程学院,上海200092;2.上海同远环境科技有限公司,上海200092)   : 采用UASB反应器处理棉浆粕黑液,比较分析了近4个月的运行中加聚合氯化铝(PAC)组与未加PAC对照组的运行过程和结果,以及有机负荷、停留时间和pH值等对两组UASB反应器运行的影响。试验结果表明,在处理棉浆粕黑液的UASB系统中投加PAC可有效加快系统的启动,并使系统具有较好的稳定性和抗冲击能力,且投加PAC对系统的产甲烷活性无不良影响。  : UASB反应器; 快速启动; 棉浆粕黑液; 聚合氯化铝:X703.1  :C  :1000-4602(2007)03-0053-04StudyonQuickStart-upofUpflowAnaerobicSludgeBlanketReactorforTreatingCottonPulpBlackLiquorWANGSu1, ZHANGLi-qun2, WUMin1, YANGJian1(1.SchoolofEnvironmentalScienceandEngineering,TongjiUniversity,Shanghai200092,China;2.ShanghaiTongyuanEnvironmentalTechnologyCo.Ltd.,Shanghai200092,China)  Abstract: TheUpflowAnaerobicSludgeBlanket(UASB)reactorwasusedtotreatcottonpulpblackliquorfornearlyfourmonths.TheoperationresultsofthegroupswithPACandwithoutPACwerecompared.Theinfluenceoforganicloadings,retentiontimes,pHvaluesandotherfactorsontheopera-tionofthetwogroupsofUASBreactorswasinvestigated.ThetestresultsshowthattheadditionofPACintotheUASBsystemtreatingcottonpulpblackliquorcaneffectivelyacceleratethesystemstart-upandallowthesystemtohaveabetterstabilityandahigherresistancetoshockloading,withoutsideeffectonthemethanogenicactivityofthesystem.
