  • 摘要: 氯代芳烃多属于一种高毒性、难降解的持久性有机污染物，对环境和人类健康具有极大的危害.因此，削减其在环境的排放至关重要.在垃圾焚烧、化石燃料燃烧、铁矿石烧结等工业过程中，除存在氯代芳烃污染物外，还常伴有酸性气体二氧化硫、氮氧化物、氯化氢和碱性气体氨气的存在.这些气体物质的共存对氯代芳烃的削减具有重要的影响.本文综述了二氧化硫、氮氧化物、氯化氢和氨气等气体物质对氯代芳烃污染物在热催化过程和光降解过程中的降解、生成及阻滞的影响作用，阐述了其影响氯代芳烃削减和生成的机理，然后对研究过程中获得的成果和存在的问题进行了总结，并对气体污染物和氯代芳烃协同去除技术的研究方向进行了展望.
    Abstract: Chlorinated aromatic hydrocarbons, as a group of toxic, difficult to degrade and persistent organic pollutant, had significantly negative impacts on environment and human health. Therefore, it is vital to minimize their release in to the environment. During some industrial processes, such as, waste incineration, fossil fuel combustion and iron ore sintering, there exist acid gases such as sulfur dioxide, nitrogen oxides, hydrogen chloride, and also basic gases, such as ammonia, in addition to the unitentional release of chlorinated aromatic hydrocarbons. These coexisting gaseous substances could be expected to have significant impact on the release of chlorinated aromatics. This paper reviews the influence of sulfur dioxide, nitrogen oxides, hydrogen chloride and ammonia on the degradation, production, and inhibition of chlorinated aromatics in thermal catalytic and photodegradation processes, and disscussed mechanism. Further development of synergetic degradation of gas pollutants and chlorinated aromatic hydrocarbons is proposed.
