火力发电厂烟气脱硫废水处理

Dispose of sewage in flue gas desulphurization for fossil-fired plant

石灰石湿法脱硫工艺是现阶段世界范围内应用最为广泛的烟气脱硫工艺。结合烟气脱硫废水的水质特点,阐述了烟气脱硫废水处理的中和、沉淀、混凝以及污泥脱水等处理工艺和研究进展状况,指出了现阶段我国在烟气脱硫废水处理研究和设计中存在的一些不足。

Limestone wet desulphurization is a FGD technology widely used the most worldwide at present. The paper discussed the treatment technology of neutralization, precipitation, coagulation and mud dehydration of sewage treatment in FGD and its research situation, and pointed out that there now exist shortcomings in research and design of FGD waste water treatment.
