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.
