【摘要】 鉴于含锰废水有毒有害，提出阴离子交换膜代替隔膜处理含锰废水。首先采用单因素法探究最佳工艺参数，在最佳条件下，电流效率为71.36%,锰回收率为85.6%,酸回收率为77.23%,能耗为7 784.78 kWh/t;电解锰的宏观形态光滑均匀，具有金属光泽。用SEM和XRD分析手段分析不同亚硒酸浓度对电解锰的影响，结果表明，当亚硒酸为0.07 g/L时，电解锰微观结构表面均匀、致密性好、光滑、无枝晶且空洞最小，晶体形态为α-Mn。更多还原

【Abstract】 In view of the toxic and harmful effects of manganese-containing wastewater, anion-exchange membrane was proposed instead of diaphragm to treat manganese-containing wastewater.First, the single factor method test was used to explore the optimum process parameters, and under the optimum conditions, the current efficiency is 71.36%,the recovery rate of manganese is 85.6%,the recovery rate of acid is 77.23%,and the energy consumption is 7 784.78 kWh/t.The macroscopic form of electrolytic manganese is smooth and homogeneous with metallic luster.The results of SEM and XRD analysis on the effect of different concentration of selenite on electrolytic manganese show that, when the selenite is 0.07 g/L,the microstructure of electrolytic manganese is uniform, densely packed, smooth, dendrite free and with minimum voids.The electrolytic manganese prepared is α-Mn with good crystallinity.更多还原
