| 摘 要： | 探讨了用热改性膨润土处理含Cu^2 废水的工艺条件，并与粉煤灰和活性炭进行了比较。实验结果表明：当Cu^2 的初始浓度不大于100mg／L时，过200目的热改性膨润土的用量为5g／L、pH=7、搅拌速度为300r／min、吸附时间30min，热改性膨润土对Cu^2 的去除率达99．5％以上。

| Abstract: | Natural bentonite is modified with calcining in this paper.Then the suitable condition of removing Cu 2 wastewater by calcining modified-bentonite is studied,and compared with fly-ash and active-carbon.The results show that when the initial concentration of Cu 2 is not more than 100mg/L,the removal ratio of Cu 2 by calcining modified-bentonite can reach greater than 99.5% under the following conditions:the dosage of calcining modified-bentonite is 5g/L,pH is 7,the stir velo- city is 300r/min and the adsorption time is 30min. |
