| 摘 要： | 利用自制不锈钢基PbO2电极与粒子电极组成三维电极处理直接绿模拟废水,研究粒子电极的电催化性能。考察了槽电压、电催化时间、电解质浓度、粒子电极投加量及粒子电极的回收利用次数等因素对直接绿模拟废水色度去除率的影响,确定较佳反应条件。对比分析铁尾矿和粉煤灰两种粒子电极的电催化性能。结果表明:槽电压6v,电催化时间4min,粒子电极投加量13g/L,电解质浓度为0.06g/L,对50mg/L直接绿废水的去除率最高可达97.98%。铁尾矿的电催化性能较粉煤灰好,但是回收利用率较粉煤灰低。

| Abstract: | Study on the electrocatalytic oxidation capacity of particle electrode PbO2 through degradation experiments of direct green wastewater was conducted.The influence of electrolyzer voltage,electrolytic time dosage of the particle electrode,electrolyte concentration,and recovery times on the chroma removal ratio of simulated wastewater was studied.Contrast analysis was carried out on the electrocatalytic oxidation capacity of tailings and fly ash.The results showed that the removal ratio of 50mg/L direct green wastewate was above 94.98%with electrolyzer voltage of 6v,electrocatalytic time of 4min,tailings dosage of 13g/L and electrolyte concentration of 0.06mol/L.The electrocatalytic oxidation capacity of tailings was better and fly ash,but the recycling was lower than fly ash. |
