The invention discloses a method for enriching scandium from titanium white wastewater. The method comprises the six steps of primary extraction, primary reverse extraction, acid dissolution for impurity removal, secondary extraction, washing for titanium removal and secondary reverse extraction. The method for enriching the scandium from the titanium white wastewater achieves comprehensive scandium recycle, the scandium recovery rate is improved from below 50% to 83% or above, extraction and separation of scandium target element and impurities are achieved, the problems of scandium loss, entrainment, emulsification and the like of a traditional process are effectively solved, the coarse scandium purity is above 36%, organic phase, alkaline liquor and acid liquor can be recycled, chemical raw material consumption and pollutant discharge are reduced, and the production cost is reduced.
