A method of recycling waste water of high salt

The present invention discloses a method of recovering high salt treatment of wastewater, by one evaporative crystallization, cooling crystallization, evaporative crystallization three secondary processing step of recovering sodium sulfate and sodium chloride. The method of the present invention is capable of high coal chemical industry wastewater salt sodium chloride and sodium sulfate was effective recovery, simple and stable process conditions, to facilitate the promotion of industrialization; sodium chloride and sodium sulfate recovered meet the quality requirements of industrial products, It can be directly recycled and reused or sold as a byproduct, not only to achieve the purpose of high-salt wastewater treatment to meet the needs of the current environmental situation, but also turning waste into treasure, to achieve resource utilization salts, improve the income of the plant.
