摘要
光催化技术作为一种高级氧化技术,具有二次污染少、反应条件温和、处理效果好等特点,在烟气治理方面具有巨大的应用潜力。本文简述了火电厂烟气中汞、SO2和NOX的污染现状,重点阐述了常见的制备光催化剂的材料以及光催化在烟气脱硫脱硝脱汞中的研究现状和应用情况,并对光催化在烟气污染治理技术研究方面进行了分析和展望。
As an advanced oxidation technology,photocatalysis has the characteristics of less secondary pollution,mild reaction conditions and good treatment effect.Therefore,photocatalysis is considered to be an enormous potential technology for flue gas purification.This article briefly describes the pollution status of mercury,SO2 and NOX in the flue gas of thermal power plants,and focuses on the current research and application of photocatalyst materials and photocatalysis in flue gas desulfurization,denitrification and mercury removal.Photocatalysis is analyzed and prospected as a smoke pollution control technology.
