Pretreatment of Pharmaceutical Wastewater by Microelectrolysis of Iron and Fenton Reagent

Abstract:

The characteristics of raw pharmaceutical wastewater was as follows: COD_Cr 30000~32000 mg/L, BOD₅ 4050~4360 mg/L, B/C: 0.12~0.14, Fe-C micro-electrolysis with Fenton reagent was adopted to pretreat this wastewater. Through static experiments analysis, optimal parameters of iron-carbon microelectrolysis Fenton pretreatment process are listed as follows: raw water pH, iron-carbon mass ratio (i.e. 2:3), the mass of iron-carbon (i.e. 500 g/L) and reaction time (i.e. 2 h). The optimal operation conditions (i.e. H₂O₂ dosage is12 mg/L, pH is 3.5, reaction time is 80 min) of Fenton reagent oxidation were confirmed.
