摘要
主要介绍了二英的结构、性质和危害及其在城市生活垃圾焚烧过程中的产生途径、二英前驱物多相催化反应、De novo反应等二英形成机理和影响二英形成的主要因素 ,并在此基础上提出了城市生活垃圾焚烧过程中二英的焚烧前控制、焚烧中控制技术和烟气、灰渣的处理技术 ,最后指出通过采用适当的控制技术和烟气、灰渣处理技术 。
This paper gives introduction of structure,property and hazard of dioxins and of the generation route,mechanisms of PCDD/Fs formation including heterogeneous catalytic synthesis from precursors and De novo synthesis and main influening factors on formation of PCDD/Fs in municipal solid waste incineration.On the foundation of these ,pre- and concurrent-combustion control technology and treatment technology of flue gas and disposal technology of ash and residue are put forward.Finally,it is indicated that emission limit of dioxin may be achieved if only proper control technology and treatment technology of flue gas and disposal technology of ash and residue are adopted.
