摘要
由于汞的危害性,汞污染已经成为了全球关注的重要的环境问题。有色金属冶炼是我国大气汞排放的重要来源之一。现在发展的烟气脱汞方法多种多样,这里介绍液相脱除烟气中单质汞的方法,包括Boliden-Norzink法,碘化钾法,硫氰化钠洗涤法,Bolchem法,Outokumpu法,湿法烟气脱硫脱汞法,以及高级氧化法。高级氧化法中双氧水和过硫酸盐作为氧化体系,通过紫外线或催化剂的活化作用后,对实现烟气中的Hg~0和SO_2等气体的联合脱除具有重要意义。
Due to the harmfulness of mercury, mercury pollution has become a global concern of the important environmental issues. Non-ferrous metal smelting is one of the important sources of atmospheric mercury emissions in China. There are many methods for mercury removal from flue gas, including Boliden-Norzink method, potassium iodide method, sodium thiocyanate scrubbing method, Bolchem method, Outokumpu method, wet flue gas desulfurization and mercury removal, and advanced oxidation. Hydrogen peroxide and persulfate as oxidizing systems in advanced oxidation process,through the activation of ultraviolet or catalyst, Which is of great significance to realize the combined removal of Hg~0 and SO_2 in flue gas.
