Abstract

Abstract:

The source，water quality characteristics and hazards of wet desulfurization wastewater were introduced and the principles，research and application progress of wet desulfurization wastewater treatment technologies such as traditional treatment technology，concentration reduction technology，solidification technology，and resource utilization technology were systematically analyzed.Comparing the advantages and disadvantages of different wet desulfurization wastewater treatment technologies，it was proposed that the chemical precipitation method was mature and widely used，but the effluent had high salt content and heavy metal content and could not be reused，which was likely to cause secondary environmental pollution； advanced treatment technologies such as concentration reduction，solidification，and resource utilization could effectively reduce heavy metal content.organic pollutants，and recover some valuable components，which could meet the requirements of zero discharge of wastewater，but the process was generally immature，and most of them were in the laboratory research stage.In view of some problems such as immature treatment technology，insignificant economic effect and slow industrial application，it was believed that front-end reduction and back-end resource treatment were the main goals of future development of wet desulfurization wastewater treatment technology.

Key words: wet desulfurization, desulfurization wastewater, treatment technology, resource utilization
