This study evaluated an anaerobic fluidized bed reactor (AFBR) that contained polystyrene particles as a support material for the treatment of vinasse that resulted from the alcoholic fermentation of sugarcane molasses. The AFBR was inoculated with sludge from an upflow anaerobic sludge blanket reactor that treated poultry slaughterhouse wastewater. The AFBR was operated with a hydraulic retention time of 24 h at a temperature of 30°C with influent vinasse concentrations that ranged from 2273 to 20,073 mg COD L(-1). The reactor was subjected to increased organic loading rates (OLR) that ranged from 3.33 to 26.19 kg COD m(-3) d(-1), with COD removal efficiencies that ranged from 51% to 70% and maximum removal at an OLR of 13.93 ± 2.18 kg COD m(-3) d(-1). The maximum biogas productivity was 5.37 m(3) CH4 m(-3) d(-1) for an OLR of 25.32 kg COD m(-3) d(-1) (average removal of 51%)..
本研究评估了一种厌氧流化床反应器（AFBR），其中包含聚苯乙烯颗粒作为支持材料，用于处理来自甘蔗糖蜜酒精发酵的酒糟。AFBR 接种了来自处理家禽屠宰废水的上流式厌氧污泥床反应器的污泥。AFBR 在水力停留时间为 24 小时、温度为 30°C 的条件下运行，进水酒糟浓度范围为 2273 至 20073mg COD/L。反应器受到从 3.33 至 26.19kg COD/m³/d 的增加有机负荷率（OLR）的影响，COD 去除效率范围为 51%至 70%，在 OLR 为 13.93±2.18kg COD/m³/d 时达到最大值。对于 OLR 为 25.32kg COD/m³/d 的最大沼气产率为 5.37m³ CH4/m³/d（平均去除率为 51%）。
