| Abstract: | Wet FGD wastewater at coal-fired power plant is of high salinity,strong corrosiveness and scale formation and not easy to reuse,which becomes one of the key factors of achieving the zero liquid discharge （ZLD） of the wastewater in the whole plant.This paper introduces the application of wet FGD wastewater ZLD technology in the coal-fired power plants at home and abroad,focuses on the analysis and comparison of the technical and economic performance of two operated wet FGD wastewater ZLD systems with evaporation and crystallization process in China,and puts forward the technology roadmap for the wet FGD wastewater ZLD systems with evaporation and concentration technology. |

| Keywords: | FGD FGD wastewater evaporation and concentration zero liquid discharge |
