The invention discloses a method for treating high-salt-content wastewater, which comprises the following steps: S1, preparing three groups of evaporators and three groups of matched forced circulation pumps, crystallization evaporation chambers, vortex separators and condensers, S2, discharging the high-salt-content wastewater into one group of evaporators, heating the high-salt-content wastewater by external steam at the moment; S3, steam obtained after evaporation of the high-salt-content wastewater entering a second set of evaporators to be heated, and S4, conveying the high-salt-content wastewater to a vortex separator through a circulating pump, and separating salt and water. The method for treating the high-salt-content wastewater has no special requirements on the types of soluble salts in the high-salt-content wastewater, the higher the salt content is, the higher the separation efficiency is, the operation period of the method is long, and the boiling and evaporation processes are carried out in a c
