摘要
本文研究了用泡沫分离法回收废水中的全氟辛酸铵,通过实验研究了气体流量、进料液流量、进料液浓度、泡沫层高度和清液层高度之比、进料液的pH值等因素对废水中全氟辛酸铵脱除率的影响,得到了最佳的操作条件,为工业设计提供了有用的参考价值。
The recovery of ammonium perfiuorooctanoate by adsorptive bubble separation methed was researched in this paper. The influences of air flux, feed flux, concentration of feed .liquid, ratio of the heights of foam vs. liquid in the tower, and PH value of feed liquid on the removed rate of ammonium perfluorooctanoate were studied and discussed. Optimal operating conditions were found. The obtained results can be used as practical basis for industry apparatus.
