Embodiment 2
[0057] The present embodiment provides a method for separating sodium salt and potassium salt. The above-mentioned separation system is used to treat the waste water containing sodium salt and potassium salt. The separation method includes the following steps:
[0058] (a) the waste water containing sodium salt and potassium salt flows to the above-mentioned crystallization separation equipment place to carry out the crystallization separation of sodium salt to obtain sodium salt crystal and sodium salt mother liquor;
[0059] (b) The sodium salt mother liquor flows to the above-mentioned heat preservation and sedimentation equipment to obtain the sodium salt magma and the first supernatant, and the sodium salt magma returns to the above-mentioned crystallization and separation equipment through the above-mentioned first discharge port to carry out the crystallization and separation of the sodium salt again ;
[0060] (c) The first supernatant liquid flows to the above-mention...
