| 摘 要： | 对经热分解法制备所得Ti基IrOr-Ta2O5涂层电极及掺杂Sn，Pb的三元氧化物电极电解处理染料厂废水及模拟有机废水进行了研究．COD测试结果表明，使用IrO2-Ta2O5／Ti电极可以电解去除废水中的有机物．随电解时间增加废水COD值降低，高COD值时电解效率高，COD值很低的有机废水中加入NaCl对电解去除有机物有很好的促进效果．电极掺杂第三元素Sn，Pb可以促进电解去除废水中的有机物，与IrO2-Ta2O5/Ti相比，PbO2/IrO2-Ta2O5／Ti电极电解废水的COD去除率提高了11．2%。

| Abstract: | The electrolysis of the wastewater in the dyestuff factory and the simulated organic wastewater was investigated with a Ti-based IrO2-Ta2O5 coating electrode produced by a pyrolytic process and a ternary oxide electrode with addition of Sn and Pb, respectively. COD experimental results showed that organic components in the wastewater could be decomposed electrolytically by using the IrO2-Ta2O5/Ti electrode. With the electrolysis time increasing, the COD value dropped. The electrolytic efficiency was high at high COD values. At low COD values, adding NaCl into the organic wastewater had a good promotive effect on the electrolytic decomposition of organic components. Adding the third elements, Sn and Pb, into the electrodes could promote the electrolytic decomposition of organic components in the wastewater. The COD decomposition rate of electrolyzing the wastewater increased by 11.2% by using the PbO2/IrO2-Ta2O5/Ti electrode compared with that by using the IrO2-Ta2O5/Ti electode. |
