摘要
随着公众对SO2污染危害的进一步认识，火电厂SO2的污染控制问题已越来越得到广泛的重视。现有火电厂多采用湿法石灰石-石膏烟气脱硫法，其脱硫效率可达95％以上。脱硫后的废水因含有多种污染因子，需经水、污泥系统处理后方可排放。
The wet limestone - gypsum desulphurization method is adopted mostly in current thermal power plants, and desulphurization efficiency can reach at more than 95%. There are many kinds of pollution factors in wastewater after desulphurization, and it can be discharged outside while passed through water and sludge treatment system.
