Method for recycling wastewater in high-salinity wastewater treatment process

The invention provides a method for recycling wastewater in a high-salinity wastewater treatment process, and belongs to the technical field of sewage treatment. According to the invention, the high-salinity water evaporation condensate wastewater is adopted to preheat the high-salinity water, the heat energy of the condensate wastewater is recycled, the temperature of the high-salinity water is increased, and the energy consumption of the MVR device for treating the high-salinity water is reduced; the cooled condensate wastewater meeting the water temperature of the vacuum pump is used as replenished water for replacement for the vacuum pump, so that extra wastewater generated by the vacuum pump in the MVR treatment process of the high-salinity wastewater is reduced, the amount of wastewater treated in the later working section is reduced, and the subsequent wastewater treatment cost is reduced; and meanwhile, condensate wastewater generated by evaporation is very low in hardness, so that the problem of scal
