铝炭微电解对含铜、镍电镀废水的处理实验研究

摘要

在铁炭微电解的基础上,研究了铝炭微电解对含铜、镍电镀废水的处理效果,考察了铝炭比、反应时间、进水pH对处理效果的影响.结果表明,铝炭微电解最佳反应时间由铁炭微电解的30 min减少到15 min;Cu2+去除率由铁炭微电解的95％提高到98％,Ni2+去除率由铁炭微电解的94％提高到97％.此项研究为铝炭微电解处理电镀废水的实际应用奠定了基础.%Based on iron-carbon micro-electrolysis process,the effectiveness of the treatment of electroplating wastewater containing copper and nickel by aluminum-carbon process has been studied. The effects of aluminum carbon ratio,reaction time,and influent water pH on the treatment effectiveness are investigated. The results show that the best reaction time of aluminum-carbon micro-electrolysis is reduced to 15 min, while that of iron-carbon micro-electrolysis is 30 min. The Cu2+ removing rate of aluminum-carbon micro-electrolysis has been increased to 98%, while that of iron-carbon micro-electrolysis is 95%. The Ni2+ removing rate of aluminium-carbon micro-electrolysis has been increased to 97% , while that of iron-carbon micro-electrolysis is 94% . This research has thus laid foundations for the actual application of aluminum-carbon micro-electrolysis to the treatment of electroplating wastewater.
