摘要
探索了用钡渣处理含铬(Ⅵ)废水的最佳实验条件,在废水pH小于6、钡渣与铬(Ⅵ)质量比为60～80、钡渣粒度为180～200目、反应时间为90min的条件下,废水中铬(Ⅵ)的去除率较高,钡渣对含铬(Ⅵ)废水的去除行为符合Langmuir等温方程.钡渣处理含铬(Ⅵ)废水的工业化应用试验表明,其工艺简单,操作方便,成本低.
The optimum experimental conditions for treating Cr(Ⅵ)-containing wastewater by barium dregs were explored.The removal rate of Cr(Ⅵ)is high when the wastewater pH is less than 6,the mass ratio of barium dregs to Cr(Ⅵ)is 60—80,the particle size of barium dregs is 180—200 mesh and the reaction time is 90 min.The removing behavior of Cr(Ⅵ)in wastewater by barium dregs accords with Langmuir isothermal equation.The industrial demonstration indicates that the process is simple,convenient to operate and with low cost.
