摘　　要：采用离子浮选法、沉淀浮选法、吸附胶体浮选法等方法处理含Cu2+废水,并对它们的效果进行了对比研究;实验结果表明,对于含有10mg/LCu2+模拟废水,使用阴离子表面活性剂SDS,当pH=10时,鼓气10min,Cu2+的去除率可以达到94.8%;与其它泡沫浮选法相比,在相同条件下,离子浮选法去除效果最好;说明去除Cu2+的主要原因是Cu2+与SDS发生了络合反应.In this paper,in the waste water containing Cu（ Ⅱ ）with 10mg/L, the removal result of Cu（ Ⅱ ）is studied by using ion flotation, precipitation flotation or adsorbing colloid flotation. The experimental results reveal that the Cu（ Ⅱ ） removal can attain a ratio of 94. 8% when SDS is added,pH is kept 10 and pumping air is stayed for 10 minutes in foam separation tower. Comparing with other foam separations, the removal of ion flotation is the best. It shows that complexing reactions occurring between SDS and Cu（ Ⅱ ） is the main reason why Cu（ Ⅱ ） in bearing water is low.
