摘要：
This paper introduced a method of using electrocoagulation-flotation technology to treat zinc-containing simulated wastewater. Effects of electrode material, polar plate spacing, initial pH value, electric current and electrolysis time on Zn2+ removal efficiency in simulated wastewater were investigated. Results revealed that Zn2+ removal efficiency was highest when aluminum was used as an anode electrode, the space between polar plates was 1 cm, initial pH value was 8, electric current was 4 A, and electrolysis time was 120 minutes. Removal efficiency of Zn2+ was 96.3% under optimal conditions.
