摘要
煤炭是我国能源结构的主体,但煤燃烧排放的SO_(2)、NO_(x)、Hg^(0)等大气污染物对人体健康和环境具有严重的危害,开发经济高效的减排技术具有重要的意义。芬顿和类芬顿基氧化系统具有氧化能力强、工艺简单、环境友好以及可实现多污染物同时脱除而受到广泛关注。综述了利用芬顿和类芬顿基氧化系统脱除多种烟气污染物(SO_(2)、NO_(x)、Hg^(0))的研究进展,污染物脱除性能、脱除机理以及各种技术的优缺点。最后还对相关脱除技术存在的主要问题和潜在的研究方向作了简要的总结和评述。
Coal is the mainstay of China’s energy structure,but the atmospheric pollutants such as SO_(2),NO_(x),and Hg^(0)emitted from coal combustion process pose serious risks to human health and the environment.Developing economically efficient emission reduction technologies is of great significance.Fenton-based and Fenton-like-based oxidation systems have attracted widespread attention due to their strong oxidation capacity,simple process,environmental friendliness,and potential for achieving simultaneous removal of multi-pollutants from flue gas.This article reviews the research progress on the use of Fenton-based and Fenton-like-based oxidation systems to remove multi-pollutants(SO_(2),NO_(x),Hg^(0))from flue gas,the pollutant removal performance,removal mechanism,and the advantages and disadvantages of various removal technologies.Finally,summary and comments were simply made on the main problems and potential research directions of the relevant removal technologies in the future.
