- Abstract
Limestone Wet flue gas desulfurization(WFGD) technology with high efficiency is being applied most widely for control technology of SO2 all over the word. It is widely used in coal-fired power plants, which will produce wastewater containing high salt and heavy metals. Currently, the desulfurization wastewater mainly adopts chemical precipitation process to dispose. but this process has many disadvantages. And the water after chemical precipitation treatment is high salinity, and easily lead to secondary pollution if discharged directly. Therefore, the zero-emission of desulphurization wastewater treatment caused more and more attention. In this paper, the advantages and disadvantages of existing treatment processes are systematically analyzed. And mainly introduced the classification, principle research status and application status of zero discharge of desulfurization wastewater treatment technology based on a comprehensive analysis and summary of the existing literature and reports . Finally,we forecast the research and development direction of the zero-emission desulfurization wastewater treatment technologies.
