Salt-containing wastewater passes through a collection tank, and after pretreatment, enters evaporation to separate out crystalline salt. The centrifuge separates crystalline salt and mother liquor from solid and liquid. The mother liquor continues to return to the evaporator to continue evaporation and concentration. The evaporated condensed water is transported to the biochemical pool for centralized treatment to meet the requirement of zero emission.
