摘　　要：针对石碑岭垃圾场渗滤液水质特性,采用以高效生物陶粒为填料的UBF反应器作酸化相,以UASB反应器作甲烷相的两相厌氧系统进行了处理垃圾渗滤液的实验研究。实验结果表明:在系统进水CODCr和BOD5质量浓度分别为3 887mg/L和819mg/L,UBF与UASB的HRT分别控制在10.3h和61.7h时,CODCr和BOD5总去除率分别为85.4%和90.1%,UBF酸化率达42.9%,BOD5/CODCr比值由0.21提高到0.39。According to the properties of Shibeiling landfill leachate, a two-phase anaerobic system composed of UBF acidification reactor with highly efficient biology ceramsite filter and UASB mechanization reactor was used to treat the leachate. The experiment results showed that when influent CODer and BOD5 concentration were 3 887 mg/L and 819 mg/L respectively, the HRT of the UBF and UASB was control at 10.3 h and 61.7 h respectively; the total removal rate of CODcr and BOD5 was 85.4% and 90.1% respectively, the acidogenic-rate of UBF was about 42.9 % and the ratio of BOD5/CODcr was increased from 0.21 to 0.39.
