- Abstract:
- Refinery wastewater was treated by a combined process of microelectrolysis/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 microelectrolysis unit of 3, Na2SO4 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.
