Removal Effect of Potassium Ferrate to COD in Different Wastewater

Abstract:

In order to research the removal effect of potassium ferrate to COD in the different wasterwater, the papermaking wastewater and the tanning wastewater were used as research objects. This paper was focused on evaluating the effectiveness of potassium ferrate preoxidation on COD removal by coagulation in different wastewater of papermaking and tanning. Potassium ferrate is a strong oxidant in the entire pH range: its redox potentials are 2.20 and 0.72 V in acidic and basic media, respectively ferrate (VI) ions will be reduced to Fe (III) ions or ferric hydroxide during the oxidation process, potassium ferrate has also the ability to act as coagulant. The removal efficiency was 78.21% to the papermaking wastewater and 85.51% to the tanning wastewater, respectively, when the dosage concentration of potassium ferrate was 20 mg/L. Altogether, potassium ferrate is a perfect sewage treatment agent to papermaking wastewater and tanning wastewater.
