采用Fenton氧化法深度处理经生化降解后的纤维素乙醇废水,考察了初始pH值、Fe2+与H2O2的投加比例(物质的量之比)、H2O2投加量与COD的比例(质量之比)以及反应时间对COD和浊度去除的影响,并通过正交实验确定了反应的最佳条件.研究表明:初始pH值、Fe2+/H2O2、H2O2/COD以及反应时间对深度处理效果有不同程度的影响;在初始pH值为3.0、Fe2+/H2O2为2∶3、H2O2/COD为2.8、反应时间为3h的最佳反应条件下,出水COD为45～56 mg·L-1,浊度为2～3 NTU,达到了纤维素乙醇废水的排放标准.“,”Fenton oxidation was employed in the advanced treatment of cellulose ethanol wastewater after biochemical degradation.The influence of initial pH,ratio of Fe2+/H2O2 (molar ratio),ratio of H2O2/COD (mass ratio),and reaction time on the COD and turbidity removal efficiencies were investigated.These parameters were selected as the variables in the orthogonal experiment performed to determine the optimum reaction conditions.The research showed that initial pH,Fe2+/H2O2,H2O2/COD,and reaction time influenced the COD and turbidity removal efficiencies to different degrees.Under the optimum reaction conditions (initial pH of 3.0,Fe2+/H2O2 of 2 ∶ 3,H2O2/COD of 2.8,and reaction time of 3 h),the effluent COD was 45 to 56 mg · L-1,and the effluent turbidity was 2 to 3 NTU,both of which measured up to the state standards of cellulose ethanol wastewater.
