摘　　要：通过分析垃圾焚烧厂SNCR烟气脱硝技术并结合渗滤液处理过程中的氨尾气处理,研究了焚烧厂采用渗滤液中氨尾气进行脱硝的可行性。研究表明,对于一座1 000 t/d中等规模垃圾焚烧厂来说,其渗滤液采用氨吹脱工艺不仅能节约生化脱氮成本,更能为烟气脱硝提供充足的还原剂氨,技术可行,为我国在"十二五"期间开展的氮氧化物减排治理工作提供参考。This paper analyzes the SNCR technology of municipal solid wastes incinerators and ammonia waste gas treatment in landfill leachate and studies the feasibility of using ammoniac waste gas from incinerators to flue gas denitrification. The research indicates,for a 1 000 t / d medium- sized incinerators,the technological processes of ammonia stripping can not only save the cost of biological denitrification,but also provide plenty of reductive ammonia for flue gas denitrification. So this technology is feasible and it can provide references for the SNCR NOx reduction treatment during the National Twelfth Five- Year Plan period.
