| 摘 要： | 针对燃煤烟气中SO2、NOx和重金属Hg等污染物,可将多个单一污染物控制系统串联进行脱除,但存在系统庞杂、运行成本高等问题,因此开发经济高效的一体化脱除技术十分必要。液相催化氧化法能够在液相中对多污染物进行联合脱除。根据使用氧化剂的不同,对不同的液相催化氧化法进行了详细论述,包括H2O2氧化法、次氯酸盐及亚氯酸盐氧化法、过二硫酸盐和过一硫酸氢盐氧化法等,总结了各种方法的优缺点,并对未来的研究方向提出了建议。

| Abstract: | The pollutants of SO2,NOx and heavy metal Hg in coal-fired flue gas can be removed by connecting multiple control systems for single pollutants,but there are problems such as complex systems and high operating cost.Therefore,economical and efficient integrated removal technologies are necessary.The multiple pollutants in liquid phase can be jointly removed by liquid-phase catalytic oxidation method.According to different oxidants used,different liquid-phase catalytic oxidation methods are discussed,including H2O2 oxidation method,hypochlorite and chlorite oxidation methods,peroxodisulfate and peroxomonosulfate oxidation methods,etc.The merits and shortages of these methods are summarized,and suggestions for future research directions are proposed. |
