| Abstract:The synergisc treatment of papermaking wastewater by using PAFC and potassium ferrate was studied, the initial quality conditions of the wastewater were as follows: pH 7.8, chroma 125, turbidity 950 NTU, CODCr 4125 mg/L, BOD5 2835 mg/L, sulphide 35.7 mg/L. The result showed that the removal rates of chroma, turbidity, CODCr, BOD5, sulfide were 85.4%, 87.8%, 89.7%, 96.5%, 92.6% when the concentrations of the potassium ferrate and PAFC were 10 mg/L and 25 mg/L, respectively. The using cost of potassium ferrate could be greatly reduced and its treatment effect could be enhanced by PAFC. |
