摘要
采用铁电极和铝电极对电絮凝处理受污染海水过程中浊度和化学需氧量(COD)去除效率进行了研究,试验结果表明:电絮凝处理海水工艺对浊度具有一定的去除效果,其去除率可达85%以上,铝电极的处理效果要好于铁电极。对电絮凝处理海水过程中COD的去除效率进行了试验研究,试验中发现电絮凝处理海水过程中剩余COD值与电流密度呈二级反应关系,并拟合出相应的动力学方程。
Turbidity and COD removal efficiency were studied during the process of electrocoagulation treatment of polluted seawater with iron and aluminum electrodes. Results showed that electrocoagulation treatment had effect on the removal of seawater turbidity. The maximum removal rate was above 85% and the treatment effect with aluminum electrode was better than that with iron electrode. The COD removal efficiency was studied during electrocoagulation treatment of seawater. The residual COD concentration and current density showed second order reaction and the corresponding kinetic equation was fitted.
