| 摘 要： | 采用微电解/芬顿/厌氧/好氧生物滤池工艺(ME/Fenton/AF/BAF)处理炼油废水,探讨了各工段的工艺参数及工艺整体运行效果。试验得到最佳工艺参数如下:微电解单元的初始pH值为3,Na2SO4投加量为0. 05 mol/L;双氧水的投加量为1. 5 m L/L; AF/BAF工段的水力停留时间为(2+2) h。在上述工艺条件下,ME/Fenton/AF/BAF工艺连续运行处理炼油废水时对COD、氨氮、油的平均去除率分别为85. 2%、85. 0%、90. 1%。

| Abstract: | Refinery wastewater was treated by a combined process of micro-electrolysis/Fenton/anaerobic biological filter/aerobic biological filter,and operational parameters of each section and the treatment effect of the whole process were discussed.The optimal operational parameters were as follows:initial influent pH of the micro-electrolysis unit of 3,Na2 SO4 dosage of 0.05 mol/L,hydrogen peroxide dosage of 1.5 mL/L and hydraulic retention time of AF/BAF section of(2+2)hours.With the above operational parameters,the average removal rates of COD,ammonia nitrogen and oil in the refinery wastewater by the combined process were 85.2%,85.0%and 90.1%,respectively. |
