Study on the Effect of Advanced Treatment of Pharmaceutical Wastewater by Coupling of Micro-Electrolysis-Catalytic Oxidation

Abstract:

Pharmaceutical wastewater was treated by coupling of micro-electrolysis-catalytic oxidation, using porous multicomponent alloys as packing. Influence of initial pH of wastewater, micro electrolysis time, packing ration, H₂O₂ dosage and catalytic oxidation time on removal rate of COD in wastewater was studied. The optimal process condition for treatment of pharmaceutical wastewater by coupling of micro-electrolysis-catalytic oxidation is as follows: initial pH 2.5, micro electrolysis time 90 min, packing ration 1:1, and dosage of H₂O₂ 2 ‰, catalytic oxidation time 120min and oxygen aeration. Under the optimal process condition, the average removal of COD is 52.5%, and the average mass concentration of COD is 276 mg/L.
