| 摘要: |
| 为提高钢渣的综合利用率,同时降低三维电催化技术中粒子电极的制备成本,利用钢渣制备出具有一定磁性的钢渣粒子电极.利用扫描电镜和振动样品磁强计对钢渣粒子电极的磁性与表面形貌进行了定性和定量表征,其磁饱和强度为 1.638 6 A·m2/kg.在设计好的三维电化学氧化系统中,研究其处理模拟印染废水的性能.结果表明：利用磁性钢渣粒子电极的三维电化学氧化系统降解模拟印染废水中罗丹明B的最佳条件为初始质量浓度5 mg/L,槽电压5 V,初始pH为4,支持电解质投加浓度为0.15 mol/L. |

| Abstract: |
| To control the production cost of the particle electrodes, a novel particle electrode was prepared using the steel slag, which has certain magnetism and could be applied for the dyeing wastewater treatment. The steel slag particle electrodes, with a saturation magnetic induction of 1.638 6 A·m2/kg, were characterized by SEM and VSM. Moreover, the prepared magnetic particle electrodes were utilized in a three-dimensional electrochemical oxidation system for simulative printing/dyeing wastewater treatment. Experimental results showed that the optimal parameters were: initial concentration of the solution of 5 mg/L, initial pH value of 4, applied voltage of 5 V, and concentration of the supporting electrolyte of 0.15 mol/L. |
