摘要
危险废物对环境的危害日趋严重,如何安全、妥善处置危险废物已成为当前环境保护的一项重要工作。本文以某危险废物焚烧处置工程为例,介绍使用"回转窑+炉排+二燃室"的焚烧处置工艺及"SNCR脱硝+急冷脱酸+干法脱酸+活性炭吸附+布袋除尘+湿法脱酸+烟气加热+活性焦吸附"的多级烟气净化工艺技术特点,可为其他危废处置工程提供参考意义。
The harm of hazardous waste to the environment is becoming more and more serious. How to dispose hazardous waste safely and properly has become an important work of environmental protection. Taking a hazardous waste incineration project as an example, this paper introduces the incineration process of "rotary kiln + grate + secondary combustion chamber" and the technical characteristics of "SNCR denitrification + quench deacidification + dry deacidification + activated carbon adsorption + bag dust removal + wet deacidification + flue gas heating + activated coke adsorption" multi-stage flue gas purification process, which can provide reference for other hazardous waste disposal projects.
