摘　　要：试验表明，自制厌氧流化床（AFB）反应器对温度的变化、上升流速等环境的变化都具备良好的稳定性。它的处理温度控制在30±2℃范围，上升表观流速控制为19．1m／h左右，回流比控制为8：1，水力停留时间在6．9h左右，废水COD去除率可达80％以上。该AFB反应器能够承受高达30．65kgCOD／m^3·d的有机容积负荷，其COD去除率也达到了73％～81％，产气速率系数为0．55～0．612m^3／kgCOD。同时，也对实验中出现的偏析现象进行了分析。The experiment shows that the self-made anaerobic fluid blanket（AFB） reactor is steady when the conditions such as temperatures, up-speed and so on are changed. The COD removal rate of brewery wastewater can reach above 80% when the temperature is remained at 30 ± 2℃ ,apparent up-speed is 19.1 m/h, reflux ratio is 8： 1, and HRT is about 6. 9 h. Its COD removal rates reach 73% -81% and the speed coefficient of gas production is 0. 55 -0. 612 m^3/kg COD when the organic volumetric load is high to 30. 65 kg COD/m^3 · d. At the same time,a segregation phenomenon appearing in the experiment is analyzed.
