- Abstract
In order to ensure the FGD (Flue Gas Desulfurization) system security and reliability, part of the wastewater should be discharge from the FGD system. Desulfurization wastewater with high salinity, high corrosion and other characteristics will lead to water pollution and waste of resources,and it is necessary to take a security and stability method to treat high concentration saline wastewater. The zero discharge treatment technology of desulfurization wastewater was proposed, and a coal-fired power plant desulfurization wastewater as the research object, designed the system process, carried out experimental study of pretreatment combined with evaporation crystallization of wastewater. In the pretreatment stage, sodium sulfate was addded to the water, and then the effluent was pumped into the evaporation crystallization unit, based on the method of gypsum crystal, the high purity sodium chloride was prepared. Pilot experimental results show that the system treatment technology for power plant desulfurization wastewater zero discharge is feasible, which can realize the crystallization salt resource; Sodium chloride salt crystals after purification for more than 99.10% purity, satisfy the standard of industrial salt optimal level, and can be utilized as industrial raw material.
