| Abstract: | The single factor experiments of saponin wastewater advanced treatment by modified fly ash and H2O2 was conducted to investigate effect of pH,reaction time,modified fly ash dosage and H2O2 dosage on water decolorization and COD removal.The optimized treatment conditions were found out through orthogonal experiment.Results showed that pH was the key factor that affecting the treatment efficiency;the optimize treatment conditions were pH 6,reaction time was 60 min,dosage of modified fly ash 10 g/L,and hydroge... |
