摘　　要：采用离子泡沫浮选和吸附胶体浮选分离法处理含Cr(Ⅵ)废水。结果表明,对浓度为10 mg/L的含Cr(Ⅵ)模拟废水,分别用Fe(OH)_3作絮凝剂和阳离子表面活性剂CTAC作捕捉剂,pH为6～10,鼓气10 min的条件下,Cr(Ⅵ)去除率分别达41.4%和50.1%。Method of ions froth flotation and adsorbing colloid flotation and separation was used to treat Cr（Ⅵ） containing wastewater. According to the test results, when Fe（ OH）3 was used as the flocculant and cationic surfaetant CTAC was used as the scavenger respectively to treat Cr （Ⅵ） containing simulated wastewater with Cr（Ⅵ） concentration of 10 mg,/L and the pH value of 6 to 10 at the condition of air -blowing for 10 rain, Cr（Ⅵ） removal rates were 41.4% and 50.1% respectively.
