The effectiveness of organics removal of an integrated electrochemical process, namely, electrocoagulation with copper ions followed by the use of electrogenerated hydrogen peroxide was evaluated with an industrial wastewater. The copper (II) ions addition into the wastewater using electro-dissolution of copper electrodes, reduces the chemical oxygen demand (COD) by 56% after 30 min of treatment, under optimal conditions of pH 2,8 and 14.2 mA cm(-2) of current density. The integrated electrochemical process reduces the COD by 78%, BOD₅ by 81%, color by 97% and fecal coliforms by 99.9%. The wastewater quality was monitored using UV-Vis spectrometry and Z-potential in order to characterize raw and treated wastewater.
采用集成电化学工艺(即电絮凝与铜离子结合后使用电化学生成的过氧化氢)去除有机物的效果,使用工业废水进行了评估。在最佳条件下(pH 值为 2、8 和电流密度为 14.2 mA cm(-2)),通过铜电极的电溶解将铜(II)离子添加到废水中,处理 30 分钟后可将化学需氧量(COD)降低 56%。集成电化学工艺可将 COD 降低 78%、BOD₅降低 81%、色度降低 97%、粪大肠菌群降低 99.9%。使用紫外-可见分光光度法和 Zeta 电位监测废水质量,以表征原水和处理后的废水。
