| 摘 要： | 采用溶胶凝胶法制备了掺杂La-Nd混合元素的Ti/Sb-SnO2电极,掺杂比例为Sn∶Sb∶La∶Nd=100∶10∶5∶4(原子质量比),通过正交实验确定该电极处理酱油废水的最佳工艺条件:电流密度40mA/cm2,电解时间90 min,极板间距4.0cm,pH值为5,在此条件下电极对酱油废水COD和色度的去除率分别为34.3%和90.11%,达到了预处理要求。

| Abstract: | In the experiment discussed in the paper sol-gel method is employed to make an elec-trode of Ti/Sb SnO2,whose atomic mass ratio of Sn∶Sb∶La∶Nd is 100∶10∶5∶4.Orthogo-nal tests show that the optimum process conditions of the treatment of sauce wastewater by this electrode is as follows：the current density is 40 mA/cm2,the electrolytic time is 90 min,the space between two plate electrodes is 4.0 cm,and pH is 5.Under these conditions,the removal rate of COD and that of color in the sauce wastewater by the electrode are 34.3% and 90.1 1% re-spectively,thus meeting the requirement of pretreatment. |
