UASCB-SMBR处理垃圾渗滤液的试验研究

Treatment of Landfill Leathate by UASCB-SMBR

研究了厌氧污泥复合床 (UASCB) 序批式膜生物反应器 (SMBR)串联工艺 ,处理垃圾渗滤液的工艺性能及影响因素 ,并与单纯的SMBR工艺进行了对比。试验结果表明 ,在进液COD浓度平均为 2 50 0mg/L ,NH+ 4-N平均浓度为 360mg/L ,厌氧反应器COD的负荷为 7～2 0kgCOD/m3·d ,SMBR负荷为 1～ 5kgCOD/m3·d,系统总水力停留时间为 1 4～ 2 8h时 ,该串联工艺COD去除率达到 92 %以上 ,NH+ 4-N的去除率在 80

The process characteristics and influence factors of combined upflow anaerobic sludge compound bed(UASCB) and sequencing membrane bioreactor(SMBR) were investigated for landfill leathate. With infuluent COD average 2500mg/L, NH^+_4-N average 360mg/L, volumetric organic loading in UASCB 7～20kgCOD/m^3\5d, in SMBR 1～5kgCOD/m^3\5d, total HRT of the system was 14～28h, the total removal rate of COD and NH^+_4-N of the process were more 92% and 80%.
