摘要
采用间歇式泡沫分离法分离废水中的铬离子。实验考察了各种操作条件对含Cr(Ⅲ )废水进行泡沫分离过程的影响 ,包括 :废水的pH值 ,表面活性剂的加入量以及气体流量等 ,确定了较佳的操作条件。实验结果也表明泡沫分离技术对含铬离子废水的除Cr
The experiment for the removal of chromium from aqueous solutions in the intermittent foam column has been done by foam fractionation intermittently. We studied the effect of the pH value of the wastewater, surfactant dosage and the velocity of the air current on separation results.The experimental results show that foam fractionation approach possesses obvious advantages in term of the overall removal efficiency and the reduction rate of Cr(Ⅲ).
