UASB/SBR陈明忠1, 岳 春2, 高艾香1(1.河南天冠燃料乙醇有限公司,河南南阳473000;2.南阳理工学院生物与化学工程系,河南南阳473004) : 对燃料乙醇生产废水进行了分质处理,对高浓度废水采用UASB/SBR工艺处理,对于低浓度废水则在其水质满足设计值时,经格栅处理后直接进入预曝池进行好氧处理即可,当其水质高于设计值时则经格栅处理后与高浓度废水一并处理。运行结果表明,在实际进水浓度高于设计值的情况下,出水水质达到了《污水综合排放标准》(GB8978—1996)的一级标准,表明工艺设计合理,处理效果良好。 : 燃料乙醇废水; 工程设计; UASB; MIC; SBR:X703 :C :1000-4602(2009)08-0049-03DesignofFuelAlcoholWastewaterTreatmentEngineeringbyUASB/SBRProcessCHENMing-zhong1, YUEChun2, GAOAi-xiang1(1.He'nanTianguanFuelAlcoholCo.Ltd.,Nanyang473000,China;2.DepartmentofBiochemistry,NanyangInstituteofScienceandTechnology,Nanyang473004,China) Abstract: Thequality-basedtreatmentoffuelalcoholwastewaterwasperformed.Thehighcon-centrationwastewaterwastreatedbyUASB/SBRprocess.Thelowconcentrationwastewaterdirectlyen-teredintopreaerationtankafterscreenwhenitsqualitymetthedesignvalue,andwastreatedinconjunc-tionwithhighconcentrationwastewaterafterscreenwhenitsqualitydidnotmeetthedesignvalue.Theoperationresultsshowthatwhentheinfluentconcentrationishigherthanthedesignvalue,theeffluentqualityachievesthefirstlevelcriteriaspecifiedintheIntegratedWastewaterDischargeStandard(GB8978-1996),indicatingthattheprocesshasrationaldesignandgoodtreatmenteffect.
