摘　　要：两相UASB反应器处理含高浓度硫酸盐黑液,酸化相为8.87L的普通升流式反应器,甲烷相为28.75L的UASB反应器,系统温度(35±1)℃。当酸化相进水COD为(6.771～11.057)g/L,SO42-为(5.648～8.669)g/L,pH值为5.5时,整个系统COD去除率平均值为74.42%;系统对负荷的冲击有较强的耐受能力。Black liquor containing a high level of sulfate was treated in two-phase anaerobic digestion. A general upflow reactor with 8.87L was used as acidification phase, the UASB reactor with 28.75L was used as methane phase. The reaction temperature was (35±1)℃.When the COD of influent in acidification phase was (6.771～11.057)g/L, SO42- was in the concentration of (5.648～8.669)g/L and pH was 5.5,the COD total removal efficiency in two-phase system was 74.42%.The system could afford fairly strong impact of loading.
