Coal-fired power plant wastewater zero discharge process system and method based on semi-dry desulfurization technology

The invention discloses a coal-fired power plant wastewater zero discharge process system and method based on semi-dry desulfurization technology. The system includes a wastewater regulation pool, anacid adding device, an alkali adding device, a medicine adding system, a folded plate flocculation pool, an inclined tube settling pool, a clean water pool, an efficient fiber filter, a filtered watertank, an electric adsorption device, a produced water tank, a cooling tower, a concentrated water tank, a desulfurization process water tank, a slaked lime bin, a flue gas circulating fluidized bed desulfurization absorption tower, a bag dust collector, a desulfurization ash bank and a chimney. The system and method provided by the invention can effectively concentrate and reduce the salt-containing wastewater of coal-fired power plants, the system produced water can be recycled as make-up water to the cooling tower, and the concentrated water can be used as the humidifying water of a flue gas circulating fluidized be
