摘　　要：为了考察生物流化床处理乙二醇废水的效果,把进入氧化沟前的乙二醇生产废水引入生物流化床中进行处理,并与氧化沟的处理效果进行对比。试验结果表明,生物流化床和氧化沟的HRT分别为15和70 h,CODCr平均去除率分别为85%和77%,去除容积负荷分别为4.16和2.85 kg/(m3.h)。单级流化床工艺出水CODCr的质量浓度大于60 mg/L,而两级串联生物流化床处理后的出水CODCr的质量浓度小于60 mg/L,平均去除率为96%,平均去除容积负荷为4.56 kg/(m3.h)。当进水水质波动范围较大时,生物流化床处理工艺比氧化沟具有更强的抗冲击负荷能力,出水水质更加稳定。In order to investigate the effect of biological fluidized bed on glycol wastewater treatment, the wastewater from glycol production was leaded into biological fluidized bed for processing before it entered the oxidation ditch, and the treatment effect was compared with that by the oxidation ditch. The test results showed that, when the HRT of the biological fluidized bed and oxidation ditch were 15 and 70 h respectively, the removal rates of CODCr were 85% and 77% respectively, the removal volume load were 4.16 and 2.85 kg/（m3·h） respectively. Using single-stage fluidized bed to treat glycol wastewater, the mass concentration of CODCr in the effluent water was above 60 mg/L. However, the mass concentration of CODCr in the effluent water from two-stage series-connected biological fluidized bed was lower than 60 mg/L, the average removal rate was 96%, and the average removal volume load was 4.56 kg/（m3· h）. Under the condition that the fluctuation range of the infuent water quality was wider, biological fluidized bed had a stronger anti-impact capability than oxidation ditch, and the effluent water quality was more stable too.
