| The feasibility of the three methods-adsorption of corncob, ultrasonic-H2O2 and ultrasonic-Fenton reagent-flocculants for the decolorization of wastewater is tested in this text. Experimental results show that both adsorption of corncob method and ultrasonic-H2O2 methods have very poor results. The hue of wastewater is almost unchanged before and after the treatment. Ultrasonic-Fenton reagent-flocculants has good result of decolorization and the hue of wastewater changes significantly before and after handling. Experiment by orthogonal design L16(44) on correlation of ultrasound time, ultrasonic power, the amount of H2O2, FeSO4 by volume, liquid effluent pH to the effect of decolorization. The result is the amount of H2O2: 3ml/l, FeSO4 by volume: 100mg/l, pH: 4. |
