Analysis and application of flue gas evaporation treatment technology for desulfurization wastewater

Abstract

Abstract:

Desulfurization wastewater，as the very end wastewater in a coalfired power plant，is of complex quality and treatmentdifficulty. As a traditional desulfurization wastewater treatment process, the‘triplet tank’technology cannot make water quality conform to the increasingly strict development situation of environmental protection in China. The emission of desulfurization wastewater has been a serious environmental problem of coalfired power plants. The demand for the zero discharge of the desulfurization wastewater is becoming more and more urgent. Using flue gas to evaporate desulfurization wastewater is feasible according to theoretical calculation and the technical road is relatively simple. The advantages and disadvantages of different technology roads of desulfurization wastewater evaporating by flue gas are compared, which provides references for the realization of the desulfurization waste water zero discharge.
