High-salinity wastewater treatment system

The utility model discloses a high-salinity wastewater treatment system. The utility model belongs to the technical field of sewage treatment, and relates to an MVR (mechanical vapor recompression) evaporator, high-salinity wastewater penetrates through heat exchange equipment and then enters the MVR evaporator, secondary vapor of the MVR evaporator is connected with a heat exchanger through a vapor compressor, saturated salt mother liquor enters a cyclone separator, centrifugate of the cyclone separator circulates to the MVR evaporator, and a thickened salt solution sequentially enters a crystal slurry tank and a centrifugal machine; part of salt-containing mother liquor of the centrifugal machine flows back to the MVR evaporator through the heat pump and the heat exchanger in a circulating mode, part of the salt-containing mother liquor is discharged to the scraper film evaporator to be evaporated, and steam carrying organic matter of the scraper film evaporator enters a sewage station to be treated after w
