摘　　要：废弃选择性催化还原法(SCR)脱硝催化剂的处理处置和资源利用是目前固体废物污染控制急需解决和突破的难题。通过Citespace文献分析软件解析国际废弃SCR脱硝催化剂处理技术的最新进展,重点比较讨论了废弃SCR催化剂处理与有价组分利用的主要工艺、需要突破的技术瓶颈和应用案例,以此提出了强化废弃催化剂产生-收集-处理-资源高值利用全过程监管的政策建议。The treatment,disposal,and resource utilization of spent selective catalytic reduction(SCR)denitrification catalysts are currently difficult problems that urgently need to be solved and overcome in solid waste pollution control.The latest progress in international spent SCR denitrification catalyst treatment technologies was analyzed using Citespace literature analysis software.The main processes for spent SCR catalyst treatment and the utilization of valuable components,the technical bottlenecks that need to be overcome,and application cases were emphatically compared and discussed.Based on this,policy suggestions were put forward to strengthen the whole-process supervision of waste catalyst generation,collection,treatment,and high-value resource utilization.
