Electrochemical Oxidation Advanced Treatment of Pharmaceutical Intermediates Wastewater after Biological Treatment Using Ti/RuO_2 Anode
Electrochemical oxidation process of curatorial effluent which dealt with microorganism was studied.Using a self-made Ti/RuO2 anode,organics,ammonia and color in solution were removed effectively.The removal rates of COD,ammonia and color were 74.2%,98% and 90%,respectively,and concentrations of COD,ammonia and color were 80 mg /L,2 mg /L and 10 multiple(diluted multiple) in electrochemical time of 150 min,at current density of 10 mA /cm2,respectively.The indexes of effluent meet "Discharge standard of primary water contaminations in chemical industry in Jiangsu province(DB 32/939-2006)".
