Effect of Electrochemical Pretreatment and Flocculation on the Degradation of Pharmaceutical Wastewater
As it is not suitable for bio-treatment method,pharmaceutical wastewater is treated by physiochemical methods in this study.Besides,potassium permanganate oxidation,electrochemical pretreatment and the addition of FeCl3 and AlCl3 after potassium permanganate oxidation were compared.It is proved that electrochemical pretreatment had a little greater degradation efficiency compared with the other two flocculants.Electrochemical oxidation seems to be more cost-effective due to its ease of operation.Electrochemical pretreatment is expected to be a suitable method to assist the pharmaceutical wastewater treatment.
