Effects of incineration conditions on dioxins from simulated municipal solid waste incineration

Funds: The project was supported by the National Natural Science Foundation of China (U20A20132, 21673270), Scientific research funds project of Liaoning education department (L2019038), the Project of the Natural Science Fund in Liaoning Province (2019-MS-221)
  • 摘要: 通过改变模拟城市生活垃圾焚烧实验的焚烧条件(加入镍催化剂、水),分析反应温度、焚烧尾气流量、尾气组分浓度、吸收液二噁英浓度、二噁英当量毒性、吸收液有机物浓度的变化,探究不同焚烧条件对模拟城市生活垃圾焚烧污染物二噁英的影响。结果表明,镍催化剂和水的加入能够促进焚烧反应过程中大分子有机物向小分子有机物转化,有效抑制了二噁英的前驱物形成,二噁英总抑制率80.7%,二噁英总当量毒性降低了98%。
