description The invention discloses a high salt concentrated liquid salt separation treatment method and system, and relates to the technical field of environmental protection water treatment. The high salt concentrate salt separation treatment method is as follows: collecting a high salt concentrate, and performing nanofiltration through a disc tube type nanofiltration membrane to obtain a permeate and a concentrate; evaporating the permeate to obtain a sodium chloride high-concentration concentrate; performing advanced oxidation and evaporation on the concentrate to obtain a sodium sulfate high-concentration concentrate; separately crystallizing and drying the sodium chloride high-concentration concentrate and the sodium sulfate high-concentration concentrate to obtain a sodium chloride solid and asodium sulfate solid. The method is reasonable in process, economical, efficient, and stable in operation. As an advanced treatment technology, the method effectively removes dissolved total solids manly comprising organic ma
