1. a water treatment method, it comprises following operation:

  • Scale inhibitor supply step, in this scale inhibitor supply step, to comprising Ca ion, SO 4the processed water supply calcium scale inhibitor of ion, carbonate ions and silicon-dioxide, described calcium scale inhibitor is the scale inhibitor that the incrustation scale preventing from comprising calcium is separated out;

    PH adjusts operation, adjusts in operation at this pH, described processed water is adjusted to described silicon-dioxide and can be dissolved in pH in described processed water;

    Desalination operation, this desalination operation is after described scale inhibitor supply step and described pH adjust operation, and described processed water is separated into condensed water and process water, described condensed water is concentrated described Ca ion, described SO 4ion, described carbonate ions and described silicon-dioxide;

    And Crystallization operation, in this crystallization operation, to the crystal seed of described condensed water supply gypsum, thus gypsum crystallization from described condensed water.
