强化UASB处理垃圾渗沥液的快速启动*李毓1,赵珊2,张春青1,费学宁1,池勇志1(1.天津城市建设学院环境与市政工程系,天津300384;2.天津市城市规划设计研究院,天津300201)摘要:实验研究了强化UASB反应器处理垃圾渗沥液的启动及其影响因素。结果表明:在启动温度为(35±1)℃,进水pH为7.3,CODCr为1122.40～2683.72mg/L时,通过一次投加粉煤灰和间歇投加阳离子聚丙烯酰胺,在运行20d左右开始出现颗粒污泥,40d左右基本颗粒化;对比实验表明,投加优势菌的UASB反应器较未投加优势菌的UASB反应器CODCr去除率可提高10%。关键词:垃圾渗沥液;UASB反应器;启动;厌氧颗粒污泥;优势菌中图分类号:X703文献标识码:A文章编号:1005-8206(2008)03-0010-03QuickStartupofReinforcedUASBinTreatingWasteLeachateLiYu1,ZhaoShan2,ZhangChunqing1,FeiXuening1,ChiYongzhi1(1.DepartmentofEnvironmentalandMunicipalEngineering,TianjinInstituteofUrbanConstruction,Tianjin300384;2.TianjinUrbanPlanningandDesignInstitute,Tianjin300201)Abstract:StartupofreinforcedUASBreactorsfortreatingwasteleachateanditsimpactfactorswerestudied.Theresultsshowedthatanaerobicgranularsludgeemergedin20daysandanaerobicsludgecouldrealizegranulationbasicallyinabout40daysinUASBreactorsthroughaddingflyashonceandcationicpolyacrylamideintermittently,whilestartuptemperaturewas(35±1)℃,pHofintakeleachatewas7.3,concentrationofCODCrwas
