Treatment of Sodium Formate Wastewater by Fenton Oxidation Process

Article Preview

Abstract:

In this study, in order to reduce the sodium formate concentration thereby reducing toxicity, the treatment of this wastewater by Fenton process was investigated. The effects of initial PH value, reaction time, concentration of FeSO4• 7H2O, and H2O2 dosage on the removal efficiency of COD were studied respectively. The experiment results show that when using Fenton oxidization pretreatment process, with pH 2.0, FeSO4•7H2O concentration 4000mg/L, H2O2(30 % ) portion 4ml/L, and reaction time 20min, COD removal efficiency was more than 50%, oxidization efficiency was good.
