The present invention relates to a desalination treatment apparatus for brackish water and a desalination method for brackish water using the same, and more particularly, a pretreatment unit for desalination of brackish water having an electrolysis unit and a pretreatment filtration unit, and the treatment treated by the pretreatment unit. The water is desalted using the ultrafiltration unit and the reverse osmosis unit of the desalination unit, and then the microbubble is generated in the treated water of the pretreatment unit and the fresh water of the desalination unit to wash the desalination unit to maximize the desalination efficiency of the brackish water. It relates to a desalination apparatus for brackish water and a desalination method used. According to the present invention, by using an electrolysis unit and a pretreatment filtration unit as a pretreatment unit, by improving the pretreatment water quality, it is possible to prevent contamination of the desalination unit and increase the freshwater recovery rate, and through a washing process using ultra-fine bubbles for the desalination unit. In addition to stably maintaining and improving the performance of the freshwater treatment unit, the lifespan of the freshwater treatment unit is also extended, and the amount of the chemical cleaner is reduced, thereby reducing the management and maintenance costs. |
