| description | The invention relates to a high-concentration salt wastewater treatment method, in particular to an evaporation-freezing coupling high-concentration salt wastewater treatment method and system based on a heat pump, which are used for solving the problem that high-quality chemical products are difficult to obtain by the existing high-concentration salt wastewater treatment method containing sodium chloride and sodium sulfate. And the defects of serious equipment corrosion, high energy consumption, high cost and high investment cost exist. According to the evaporation freezing coupling high-concentration salt wastewater treatment method based on the heat pump, a high-quality mirabilite product and a sodium chloride product are prepared according to the principle that the solubility of inorganic salt such as sodium chloride and sodium sulfate at different temperatures is different, and a refrigerant is adopted to replace circulating cooling water for heat exchange; and the steam generated in the preparation proc |
