This paper introduces the detailed design of near zero discharge project of high-salt mine water in a certain mine,and analyzes the water quality of high-salt mine water,the process of raw water regulating pre-sedimentation tank-heavy medium velocity dust device-ultrafiltration-reverse osmosis membrane desalination-high efficiency sedimentation tank-v-type filtration-weak acid cation bed resin-decarbonization tower-reverse osmosis-concentrated water-evaporation pretreatment-ozone oxidation-MVR evaporation crystallization-salt-mixing drying was designed.This paper mainly expounds the main technological processes and characteris-tics of the process,the segmented layout of near zero discharge technology for high salt mine wa-ter,the brief description of the construction(structure),equipment and facility parameters,the a-nalysis of project budget and operation cost,a set of mature,economical and advanced engineering design examples are completed,which provide reference and guidance for the near zero discharge project of high-salt mine water in surrounding coal mines.
