摘　　要：煤炭燃烧产生大量二氧化硫(SO_(2))和氮氧化物(NO_(x))。随着多污染物控制技术的改进,燃煤电厂的污染物控制成效明显,但锅炉烟气污染仍未得到有效控制。本文首先介绍了高级氧化法的原理和特点,简述了Fenton法、臭氧氧化法和光催化氧化法三种方法,并进行对比与分析三种方法的优缺点,进而通过预实验探究了铁酸铜(CuFe_(2)O_(4))活化过硫酸氢钾(PMS)用于脱硫脱硝实验的可行性。预实验结果表明,NO_(x)和SO_(2)的脱除效率分别可达到80%、59%和99%。The combustion of coal produces large amounts of sulfur dioxide (SO_(2)) and nitrogen oxides (NO_(x)).With the improvement of multi-pollutant control technology,the pollutant emission control of coal-fired power plants has achieved obvious results,but the boiler flue gas pollution has not yet been effectively controlled.The advantages and disadvantages of Fenton method,ozone oxidation method,and photocatalytic oxidation method were analyzed.Through preliminary experiments,the experiments feasibility of copper ferrite (CuFe_(2)O_(4))/potassium permonosulfate(PMS) was explored.As a result,it shows that the removal efficiencys of NO_(x) and SO_(2) reach 80%,59%and 99%,respectively.It provides data support and theoretical basis for desulfurization and denitrification technology based on advanced oxidation methods.
