Abstract: The influence factors of sepiolite modification and application in sauce wastewater treatment by orthogonal test were studied. The results showed that acidity was the main factor of sepiolite modification, and the decoloration effects of sauce wastewater was efficiency at acidity of 4%, reaction temperature of 120℃, time of 12 h. When COD concentration was 1.033 mg/L, the dosage of modified sepiolite was 3 g(the liquidsolid ratio was 70∶1), the reaction time was 90 min, the pH value was 5, the removal rates of COD and color could reach 59.6% and 76.4%, respectively.
