城市空气颗粒物开放源理论与治理技术研究进展

Progress on Theory and Control Technology of Urban Airborne Particulate Matter Open Source

城市空气颗粒物开放源已成为大气颗粒物的主要来源之一,它对改善我国城市空气环境质量具有重要意义。开放源是一种复合源类,具有源强不确定和排放不连续等特点。其所排放的主要污染物是扬尘。但目前只有少数的开放源类起尘量可以进行估算。国内外一般对城市空气颗粒物开放源的防治对策有生态环境综合整治或生态修复治理、湿法防尘、将堆放物用覆盖物覆盖或封闭储存等。

Urban airborne particulate matter open source has been one of the main sources of airborne particulate matter. It's significant for improving the quality of urban ambient air of China. The main pollutant emitted from open sources is resuspended dust. Dust emission inventory of few open source can be evaluated now. The main control measures include restoration of environment, wet dust prevention, and covering piles of material with shroud or close stockpiling piles.
