摘　　要：在(38±2)℃条件下,分别采用UASB和UBF厌氧反应器技术对生活垃圾渗滤液进行处理。结果表明:在厌氧运行过程中,有机负荷提升至15 kg COD(m^3·d),HRT为5 d,UASB厌氧反应器原料产气率为25.4~29.6 mm^3/t,COD去除率高于94%,容积产气率为5.77~6.02 m^3/m^3,CH_4含量70%以上,pH值为7.21~8.25;UBF厌氧反应器原料产气率为22.7~25.4 m^3/t,COD去除率高于90%,容积产气率为4.99~5.60 m^3/m^3,CH_4含量66%左右,pH值为7.29~8.01。UASB厌氧反应器处理生活垃圾渗滤液效果优于UBF厌氧反应器。Under the condition of（ 38 ± 2） ℃,landfill leachate was treated by UASB and UBF anaerobic technology under high organic loading rate. Results showed that in the anaerobic process,the organic loading rate increased to 15 kg COD/（ m^3·d）and HRT was 5 d. In UASB anaerobic reactor,raw material gas production rate was 25. 4 ~ 29. 6 mm^3/t,the removal rate of COD could be more than 94%,volumetric biogas production rate was 5. 77 ~ 6. 02 mm^3/m^3,content of CH_4 was more than 70%,and pH was 7. 21 ~ 8. 25. In UBF anaerobic reactor,raw material gas production rate was 22. 7 ~ 25. 4 mm^3/t,removal rate of COD could be more than 90%,volumetric biogas production rate was 4. 99 ~ 5. 60 m^3/m^3,content of CH_4 was about 66%,and pH was 7. 29 ~ 8. 01. UASB anaerobic technology was better than UBF anaerobic technology in the treatment of landfill leachate.
