摘　　要：概述了国内外脱硫、脱硝、脱汞及其联合处理技术的研究进展和应用状况,并对各种技术所具有的优势和存在的不足进行了评述。详细介绍了活性焦干法脱硫脱硝脱汞技术的机理和工艺特点,分析了采用活性焦进行干法脱硫脱硝脱汞一体化技术的技术优势和发展趋势。通过采用活性焦干法脱硫脱硝脱汞一体化技术处理模拟烟气和在工业上的应用成果,表明了活性焦联合脱除SO2、NO和Hg一体化技术的可行性。The development and application of the desulfurization, denitration, de-mercury and C-de-SO2/NOx/Hg technologies are reviewed in this paper, and the advantages and disadvantages of various technologies are discussed, respectively. Then the C-de-SO2/NOx/Hg technology based on activated coke were analyzed in emphasis on the mechanism, technical characteristic and developmental trend, which was used in laboratory and industry successfully. It is concluded that the C-de-SO2/NOx/Hg technology based on activated coke is feasible and should be applied more widely.
