摘　　要：为了评价多环芳烃作为二(口恶)英前驱物经由前驱物途径生成二(口恶)英反应途径的可能性,并找出能作为二(口恶)英在线监测的可能指示物,本文在小型管式炉上进行了原生垃圾和煤混合燃烧试验。结果表明,随着硫氯摩尔比的增加,生成的多环芳烃总量呈下降趋势,和二(口恶)英总量变化的趋势相同,多氯二苯并呋喃(PCDFs)的总量和多环芳烃总量的变化趋势比较相似,存在着一定的关联性。其中苯并[a]蒽(BaA)和PCDFs的关联性非常大,苯并[a]蒽有可能作为PCDF监测的可靠的指示物之一。In order to check the relation between PAHs and dioxins formation, the paper evaluated the possibility of dioxins formation from PAHs via precursor pathway, as well as the corresponding mechanism in municipal solid waste （MSW） incineration process. The incineration experiment mixed proportionally by municipal solid waste and coal on a fixed-bed had been done, then the PAHs and dioxins formation performance were studied. With the increase of S/Cl ratio, the total PAH emission decreases, and this trend is similar with that of dioxins emission. It shows that the correlation between PCDF and PAHs is obvious. Especially the correlation between Benzo（a） anthracene and PCDF is very obvious, so BaA may be one of typical PCDF indicators.
