摘　　要：尿素由于运输、储存安全性较高,作为还原剂进行脱硝备受关注。从工艺原理、系统组成和工程应用等方面,对尿素制氨选择性催化还原技术(SCR)、选择性非催化还原技术(SNCR)和尿素法三种脱硝方法进行了综述。分析了不同技术运用过程存在的问题,并提出解决措施。Because of safety in transport and storage,denitrification technology with urea serving as reducing agent has attracted more and more attention. The mechanism of denitrificaion ,technology system and engineering application were reviewed,which were related to Selective Catalytic Reduction ,Selective Non- Catalytic Reduction and urea route. Then,the problems existing in the process of application were analyzed,and solving measures were put forward.
