Strong brine concentration and reduction system

The utility model discloses a concentrated brine concentration and decrement system which comprises a tempering water tank, a silicon removal unit, a ph callback pool, an oxidation unit, a filtration pretreatment device, an ion exchange device, a carbon remover and a concentration and decrement device, the silicon removal unit, the ph callback pool, the oxidation unit and the filtration pretreatment device are connected between the tempering water tank and the ion exchange device, and the ion exchange device, the carbon remover, the ion exchange device water production tank and the concentration decrement device are sequentially connected. When the system is used for treating the high-salinity concentrated water, the water quantity of the concentrated water can be reduced, the salt content of the concentrated water is improved, and the high-salinity wastewater is recycled through the evaporative crystallization device; the device is used for treating high-salinity wastewater of a power plant, produced fresh w
