Abstract

On the basis of the quality characteristics of flue gas desulfurization waste water

the conventional wastewater treatment techniques and their existing problems are introduced.Four kinds of zero discharge processes are focused on

such as the "pretreatment-evaporation-crystallization" process

the comprehensive utilization of slag waste heat

the coal yard spraying and the evaporation in high temperature flue duct.The key problems and research directions of each process are elaborated.Moreover

the technological process and economic-technology index of different methods are compared

to provide references for desulfurization wastewater treatment in thermal power plants.
