Research on Experiment and Technology of Emulsion Liquid Membrane Applied to H Acid Wastewater Treatment
In this experiment, we use the removal rate of COD as index to optimize membrane composition and operating parameters formula by 3 stage countercurrent liquid membrane extraction and also study the influence of different water to emulsion Rew on COD removal rate .The experiments showed that Rew and the external phase pH have significant effects on the removal rate of COD and the total removal rate of COD reached 85.3% when Rew=1:1.0 under the condition of 3 stage countercurrent extraction.
