两种UASB+好氧组合工艺处理生活污水试验研究孙朝霞,李清雪(河北工程大学城建学院,河北　邯郸　056038)摘　要:对UASB与跌水曝气和曝气生物滤池种组合工艺对生活污水的处理效果进行研究,并对跌水曝气和曝气生物滤池作为厌氧后处理的可行性作进一步的探讨。研究表明,UASB反应器在厌氧出水后加后续的好氧处理装置如跌水曝气和曝气生物滤池,能有效去除生活污水中的COD,与只用UASB反应器相比去除率分别提高了28.4%和44.1%,总平均去除率约90%。氨氮的浓度也降低,但去除率较低。因此,可以认为UASB厌氧反应器与好氧组合工艺处理生活污水是可行的。关键词:生活污水;UASB;跌水曝气;曝气生物滤池TwoUASBandAerobicCombinedTreatmentofDomesticWastewaterSUNZhao-xia,LIQing-xue(HebeiEngineeringUniversity,CollegeofUrbanConstruction,HebeiHandan056038,China)Abstract:Theeffectoftreatmentofdomestic-sewagebyUASBrespectivelycombinedwithhydralicdropaerationandaerationbiologicalfiltrationwastewatertreatmentprocesswasstudied,andthefeasibilityofpost-processingwasgotfurtherexplored.TheresultshowedthatCODcanberemovedeffectivelybythetreatmentUASBcombinedwithaerobictreatment,suchashydralicdropaerationandaerationbiologicalfiltration.TheremovalefficienciesofCODenhanced28.4%and44.1%whenUASBrespectivelycombinedwithhydralicdropaerationandaerationbiologicalfiltration,com-paredwithonlybyUASB.Thetotalaverager
