摘　　要：选矿废水排放量大,环境污染严重,因此实现选矿废水回用意义重大。本文根据氧化铜选矿废水性质,考查了絮凝剂种类对沉降指标的影响,试验结果表明,复合絮凝剂XS-1(主要成分为PAC和PAM)效果最佳;沉降试验结果显示当复合絮凝剂用量为2 m L时,废水沉降速度最快,固体悬浮物含量从1629 mg/L大幅降至168 mg/L,COD和重金属离子浓度也有所降低;废水回用试验结果表明,采用XS-1处理后选矿废水回用对氧化铜选矿指标几乎没有影响。As the propertied of the large quantity and severe environment pollution,it is particularly significant to reality the Reutilization of ore dressing wastewater.According to the properties of copper oxide wastewater,the test to study the influence of different kinds of flocculants on the sedimentation index has been conducted. The results showd that the combined flocculants XS-1 performance the best settleability to the wastewater,and when the dosage is 2ml,the settling velocity is the fast and the suspended solids content reduced from 1629 mg/L to 168 mg/L,as well as the content of COD and heavy metal ions. Test results of wastewater reusing tests indicated that it had no effect on the copper ore dressing index by using the water treated by XS-1.
