摘　　要：煤炭依然是我国最主要的能源,其燃烧排放的SO_(2)和NO(x)是近阶段最主要的大气污染源。本文详细论述了新型氧化剂材料黄磷及副产物泥磷的理化性质,并对国内外乳化黄磷、泥磷法脱硫脱硝的研究现状及运行反应机理进行了综述,探索了新技术与现有技术的异同,总结认为含碱黄磷、泥磷脱硫脱硝属于低成本高效率的新技术。此外,介绍了PhoSNO(x)技术的工程应用及其净化效果,并对该技术未来的应用前景进行了展望。Coal is still the most important energy in our country,and the SO_(2) and NO(x) emissions from its combustion are the most important sources of air pollution in the recent period.In this paper,the physical and chemical properties of the new oxidant material,yellow phospho-rus,and its by-product sludge phosphorus were discussed in detail.The status and operational reaction mechanism of desulfurization and denitrification by emulsified yellow phosphorus and slurry phosphorus process in the domestic and international research were summarized.Ulteriorly,the similarities and differences between the new technology and the existing technology were explored.It was concluded that the desulfurization and denitrification by alkali-containing yellow phosphorus and slurry phosphorus were a new technology with low cost and high efficiency.In addition,the engineering application of PhoSNO(x) technology and its purification effect were introduced with examples,and the application prospect of this techno-logy in the future was prospected.
