Abstract: A zero discharge-oriented hybrid desalination method according to the present invention includes a separation membrane penetration process for allowing seawater to penetrate a separation membrane to be separated into primary product water and primary condensate water; an electrodialysis process for separating the primary condensate water into secondary product water and secondary condensate water by electrodialysis; and a evaporative concentration process for separating the secondary condensate water into tertiary product water and tertiary condensate water by evaporative concentration. According to the zero discharge-oriented hybrid desalination method of the present invention, the separation membrane penetration process, the electrodialysis process, and the evaporative concentration process are configured to be conducted sequentially. Accordingly, the amount of the product water which is fresh water can be maximized and the amount of energy consumed to this end can be minimized. Specifically, the capacity of water intake equipment can be half of those of existing processes, the amount of the product water increases to 1.7 to 2.0 times of those of the existing processes, the amount of the discharged condensate water is equal to or less than 10% of the water intake amount, value added resources can be recovered with relatively little energy since high-salt condensate water with a salinity of at least 30% is generated, and the zero discharge of the intake seawater can be realized.
