Abstract | A method for treating a water-containing substance, including: mixing a water-containing substance with a solvent at a first temperature to obtain a mixture containing a solid substance and a liquid substance; conducting a first separation treatment of the mixture to obtain the solid substance and the liquid substance; and conducting a second separation treatment of the liquid substance obtained by the first separation treatment at a second temperature to obtain an aqueous phase and an organic phase, the organic phase contains the solvent. The mutual solubility of the solvent and water at the first temperature is higher than that of the solvent and water at the second temperature, so that the separation and recovery of water is achieved by liquid-liquid separation without phase transition in the method for treating a water-containing substance, so the energy consumption can be effectively reduced. The invention further relates to a corresponding device. |
