摘　　要：研究了石灰乳絮凝沉降法同时去除废水中铁和铜。实验研究了不同操作变量,如溶液pH值,石灰的配比,反应时间等对铁和铜(主要是铁)的去除率的影响。在适宜的操作条件下,废水中的铁和铜去除率高达99%,处理后残液中铁的浓度小于3 mg/L,铜的浓度为0.3 mg/L。The lime flocculation sedimentation and removal of copper and iran with this methad were studied.The effect of parameters,as pH value,ratio of lime and water,and reactive time on removal ratio were presented.The results showed that above 99% iron and copper can be removed from waste water with this method in proper conditions,the concentration of iron and copper in the treated waste water were less than 3 mg/L and 0.3 mg/L,respectively.
