Abstract

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.
