【Abstract】 The decolorization of dyeing and printing wastewater by ceramic membrane microfiltration combined with adsorption of magnesium hydroxide was studied. Main attentions were paid to select proper conditions of chemical pretreatment and microfiltration process. The results show that the technology of ceramic microfiltration combined with adsorption of magnesium hydroxide was feasible for decolorization of wastewater containing active dye. Under the approprite operation conditions,the decolor rate of wastewater was more than 98%, and the flux of 1.0 μm membrane was about 150 L/(m 2·h).更多还原
