“…However, flue gas evaporation technology is limited in its application to the removal of fine particulate matter from desulfurization wastewater due to the slow evaporation rate and agglomeration efficiency of fine particles. In order to address this topical issue and to improve the removal efficiency of flue gas evaporation techniques, Lu et al [38] proposed a droplet evaporation technique for charged desulfurization wastewater and studied the effects of induction electrode voltage, atomization pressure, Cl − concentration, and other factors on the agglomeration of fine particles and the charge transfer characteristics between droplets and particles.…”

Desulfurization wastewater is industrial wastewater with a high salt content, high metal ions, and high hardness produced by flue gas desulfurization of the limestone-gypsum method in coal-fired power plants. This paper summarizes the source of desulfurization wastewater, water quality characteristics, water quality impacts, and other factors, combined with the current status of research worldwide to introduce the advantages and shortcomings of the existing desulfurization wastewater treatment technology. In addition, zero liquid discharge technology as a novel method to treat desulfurization wastewater is also summarized. It mainly includes evaporation and crystallization, flue gas evaporation, membrane distillation removal, etc. Finally, this manuscript looks forward to the future development direction of desulfurization wastewater based on its existing technology and emission standards.
