| 摘 要： | 针对城市生活垃圾焚烧（MSWI）过程中二（口恶）英类的生成机制以及焚烧飞灰的组成,研究了MSWI飞灰中常见的钙化合物（CaO,Ca（OH）2,CaCl2,CaSO4及Ca（NO3）2）对前生体五氯酚（PCP）及六氯苯（HCB）生成二（口恶）英类的阻滞作用.结果表明,280℃下加热2 h,Ca（NO3）2,Ca（OH）2和CaO对PCP生成二（口恶）英类的总阻滞效率分别为93.7%,80.4%和98.9%,而CaCl2和CaSO4几乎没有效果.CaO对PCP和HCB混合物生成二（口恶）英类物质同样具有良好的阻滞效果.另外,探讨了上述钙化合物对PCP及HCB生成二（口恶）英类的阻滞作用机理.
