【摘要】 利用活性炭吸附法处理含铬废水,对处理的工艺条件进行系统研究,确定吸附平衡时间为7 h,给出吸附等温方程式q=0.161c1.666 1及穿透曲线.从吸附等温线可知含铬(VI)水溶液吸附符合Freundlich型.对活性炭进行再生处理,结果表明,利用活性炭吸附处理含铬废水,具有处理效果好,操作简单,再生容易等优点.更多还原

【Abstract】 Adsorption of wastewater containing chromium(Ⅵ) on activated carbon was studied.The operation conditions of dynamic adsorption had been investigated.Equilibrium time is seven hour,isothermal equation is q=0.161 ρ~1.666 1 and penetrated curve of adsorption was obtained.The adsorption isothermal equation can be represented by Freundlich isotherm and the activated carbon was regenerated.The results showed that it was successful in treating wastewater containing chromium(Ⅵ) by dynamic adsorption on activated carbon.更多还原
