| 摘 要： | 采用批实验方法,研究颗粒铁（铁屑）加入量、Cr（Ⅵ）初始浓度及阴离子组分对颗粒铁去除铬动力学影响。结果表明,在室温条件下（24℃±2℃）,不调节溶液的pH值,铁能很快去除水中的铬;随颗粒铁加入量的增加、初始Cr（Ⅵ）浓度的减少,颗粒铁对铬去除增强,较高浓度时,氯离子、硫酸根离子和重碳酸根离子对颗粒铁除铬有适度的增强;低浓度时,HCO3^-轻微减弱颗粒铁对Cr（Ⅵ）的去除。探讨了各因素对铬去除的影响机理。

| Abstract: | The kinetics effect of granular iron addition amount , Cr （ Ⅵ ） initial concentration and anion component on Cr（Ⅵ ） reduction by granular iron are studied in batch systems. The result shows,chromium can be quickly removed by iron at room temperature （24 ℃±2 ℃ ）, no adjusting pH value, Cr（ Ⅵ ） reduction rates increases with increasing iron addition amount and decreasing initial Cr（Ⅵ ） concentration. The chloride,sulfafe ion and bicarbonate ion has moderate enhancement function at high concentration, bicarbonate ion has slight weakens reduction effect at lower concentration. The influence mechanism of various factors to chromiam reduction. |
