| 摘 要： | 以蒙脱石、粉煤灰为原料,添加一定量的粘结剂混合造粒制成复合颗粒吸附剂,用于处理含Zn2+废水,实验研究了吸附反应时间、吸附剂投加量、废水初始浓度及介质pH值对吸附性能的影响。研究结果表明:蒙脱石/粉煤灰复合颗粒吸附剂的最佳吸附工艺条件为:在室温下,吸附反应时间50 min,吸附剂投加量5.0 g/L,初始浓度40 mg/L,溶液pH值为5。在此条件下处理含Zn2+废水,吸附去除率为95.77%,处理后残余浓度为1.69 mg/L,达到国家一级排放标准(2.0 mg/L)。

| Abstract: | Granulated absorbent were prepared by using the mixture of montmorillonite,fly ash and a certain amount of cementing agent.The granulated absorbent was used to treat the waste water containing Zn2+.The adsorption reaction time,the initial concentration,the amount of absorbent,and the medium pH were investigated.The experimental results showed that the optimal technological conditions of adsorption were as follows: At the room temperature,the adsorption reaction time was 50 min,the amount of absorbent was 5.... |
