The invention discloses a method for resourceful treatment of high-salt wastewater. The method comprises steps as follows: (1) sodium sulfate type salt-containing wastewater is deeply filtered and oxidized, so that the content of COD is reduced to 30-50 ppm; (2) deeply oxidized effluent enters an evaporating system to be highly concentrated; (3) the concentrated slurry and potassium chloride are mixed, and large-particle potassium sulfate products are prepared through conversion and crystallization; (4) evaporative crystallization is performed. According to the method, zero discharging of wastewater is basically realized, a large amount of industrial recycled water is obtained, a product with a high added value is prepared after secondary conversion of inorganic salt with low output value, reduction, recycling and harmlessness of the high-salt wastewater are realized, and strategic structure adjustment, optimization and upgrading of the environmental protection industry are pushed.
