【Abstract】 The alkali ammonia etching wastewater is treated with the electrolytic method. The influence of the electrode distance, electrolytic time and current density on treatment effect is inspected. The result of study indicated that the electrolytic method can remove copper ions of the alkali ammonia etching wastewater effectively, and reclaim metal copper. When the electrode distance is 28 mm, and current density is 100～300 A/m 2,the percentage of removal of copper ions is above 99 %.更多还原
