摘要
文章介绍了高浓度铜的去除方法,特别是对络合铜的去除,主要有碱沉淀法、硫酸亚铁共沉法、铁置换法、S^(2-)沉淀法等4种方法。对它们的技术特点进行了概述,对比分析认为采用硫化钠与硫酸亚铁结合方法处理高浓度络合铜废水最为实用。
The methods for removing copper from industrial waste water have been discussed ,especially for the removal of high copper-complexes content. The four methods, i.e., alkaline precipitation, co-precipitation with ferrous sulfate,ferrous replacement and S^2- precipitation were discussed in detail, and the project with Na2S and FeSO4 is the best one in cost.
