The activity of bentonite was improved by the high temperature roasting and the decolorization of waste hydraulic oil by the modified bentonite was studied. The results showed that the best conditions in the process of modified bentonite were:the roasting temperature 450℃,the calcining time 2h. The optimum decolorization conditions on the waste hydraulic oil were:the addition of modified bentonite was 15%,the temperature was 90℃and the time was 20min in vacuum. Under these conditions,the decolorization rate of the product was 94%.
