The invention relates to the technical field of water treatment, and particularly relates to and discloses a treatment method for recycling high-hardness and high-salinity waste water. The treatment method comprises the following steps: (1) removing organic matters, softening and removing salt for the first time by using a primary treatment system; (2) removing organic matters, softening and removing salt for the second time by using a secondary treatment system; (3) performing evaporation and freezing crystallization treatment on concentrated liquid. According to the treatment method for recycling high-hardness and high-salinity waste water, a physical and chemical treatment and membrane integrated technology and an evaporation and freezing crystallization technology are combined, high-quality water can be recycled, the resin is softened to regenerate internal supply of an acid and alkali medicament, industrial salt is generated, resources are utilized effectively and comprehensively,long-term effective and stable operation of the system is guaranteed, and the advantages of good treatment effect, stable and reliable operation and capability of completely utilizing resources are achieved.
