【Abstract】 The desulphurization wastewater from coal-fired power plants is characterized by high salinity,complex components,difficult to be treated,and its direct discharge can cause serious environmental pollution. Several kinds of zero-discharge technologies for desulphurization wastewater having application prospects are introduced, and the principles,advantages and disadvantages of different treatment technologies analyzed. The development trend of desulfurization wastewater treatment technology in coal-fired power plants is predicted and the advantages of using bypass flue and bypass spray drying zero-discharge treatment technologies are pointed out. On this basis,the exploration of efficient,clean,and low-cost zero-discharge treatment technologies will be the research emphasis in the desulfurization wastewater discharge field.更多还原
