电吸附法处理低浓度含铜废水研究

Research on the Treatment of Low Concentration Wastewater Containing Cu^(2+) by Electrosorption

研究了电吸附法关键工艺参数对低浓度含铜废水处理效果的影响以及电脱附再生活性炭纤维毡电极的可行性。结果表明,在最佳条件下Cu^(2+)去除率可达84.6%,工作电压、极板间距、进水流量及回流均对除铜效果有较大影响。电极经过6次电吸附和电脱附再生仍然能够保持良好的吸/脱附性能,除铜效果稳定。

The influence of critical operating parameters on electrosorption performance of low concentration wastewater containing Cu2＋ by electrosorption and the feasibility of electrosorption for the recycling of activated carbon fiber felt （ACF felt） electrode were investigated. Under the optimal condition, the removal rate of Cu2＋ was 84.6 %. The experimental conditions including applied voltage, electrode distance, influent flow and reflux ratio greatly affected treatment performance. After six cycles of electrosorption/desorption, ACF felt electrodes showed good performance and Cu2. removal efficiency remained stable.
