摘　　要：SO2是现今主要的大气污染物,而我国以煤为主要燃料的特点使SO2的污染日益严重。因此,控制SO2的排放,积极应用二氧化硫控制技术,对改善大气污染状况至关重要。介绍了传统的石灰石-石膏法,探讨了硫酸亚铁法、有机胺法、尿素法、亚硫酸钠循环法、柠檬酸钠循环法、过氧化氢法等应用新型吸收剂的湿法烟气脱硫技术,并对它们的优缺点做了简单评述。SO2 is now one of the main atmospheric pollutants. The current situation of the coal as the main fuel in China, the pollution caused by SO2 is becoming increasingly serious. Therefore, controlling the emission of SO2 and employing all kinds of desulphurization technologies are essential to improve the status of air pollution. The traditional limestone - gypsum method was analyzed and the application of some new wet flue gas desulfurization technologies, such as ferrous sulfate method, organic amine method, urea method, sodium sulfite circulation method, sodium citrate cycle method, and hydrogen peroxide method, etc, were reviewed. A simple comment on the advantages and disad- vantages of different desulphurization processes was made.
