Decolorization of the Wastewater Containing Crystal Violet by Foam Separation
泡沫分离法处理结晶紫染料废水的工艺

The decolorization process of wastewater by foam separation was studied by using aqueous solution of crystal violet as a research system. The influences of pH value, gas flow rate, concentration of surfactant and volume of the solution on the decolorization process were investigated by using sodium dodecyl benzene sulfonate (SDBS) as the surfactant. The optimum conditions were determinated by the orthogonal test method. The results show that under the optimum conditions of pH 11.0, gas flow rate 0.018 m3/h,...
