摘要 采用Fenton法处理膜提取渗滤液MBR-NF截留液中腐植酸产生的超滤透过液。考察了Fe^(2+)投加量、n(H_2O_2)/n(Fe^(2+))投加比、初始pH等因素对COD及UV_(254)去除率的影响,并在最佳实验条件下对该反应去除COD过程的动力学过程进行分析与讨论。结果表明,最佳反应条件为:Fe^(2+)投加量为0.07mol/L,(H_2O_2)/n(Fe^(2+))投加比为3,初始pH为7.06。在最佳条件下,COD和腐植酸(UV_(254))的去除率分别为61.23%和89.12%。Fenton法处理膜提取腐植酸过程中产生的超滤透过液的COD去除过程符合二级反应动力学方程。
