摘要

摘要: 采用自主设计的喷射床电沉积装置处理模拟采矿含锌废水。通过改变喷射床电沉积处理过程的pH值、电流强度、含锌废水浓度以及鼓入氮气等实验参数,研究不同处理条件下喷射床电沉积反应器对含锌废水的处理效果。结果表明:废水Zn²⁺浓度为1000 mg/L时,采用粒径为1.8 mm铜微粒电极,反应过程pH值为4.5,恒电流强度为15 A,向废水中鼓入600 L/h氮气的条件下处理效果最好,电沉积反应180 min后,Zn²⁺去除率达到49.44%,平均电流效率为41.63%。并以实验结论为基础,通过动力学模拟分析,建立了单金属离子电沉积过程的动力学模型,验证了实验结果的可靠性和准确性。

Abstract: Experiments were carried out by using self-designed spray bed electro-deposition devices to treat zinc-containing wastewater under different conditions including pH value, current intensity, zinc ions concentration and bubbling nitrogen. The effect of the spray bed electro-deposition system on treatment of zinc-containing wastewater was investigated and the parameters were optimized. The results showed that the optimized condition was as follows:the particle size of electrode of 1.8 mm, zinc ions concentration of 1000 mg/L, wastewater pH value of 4.5, current value of 15 A and bubbling nitrogen of 600 L/h, then the removal rate of zinc ions was up to 49.44% and the current efficiency was 41.63%. On this basis, the dynamic model of single metal ion electro-deposition was established by dynamic simulation analysis, which proved the reliability of the measured data and the accuracy of the experimental results.
