随着我国经济社会的不断发展,对空气和环境质量对人体健康的影响日益受到人们广泛关注。在公路工程建设过程中所产生的扬尘给环境带来的影响越来越引起研究人员的高度重视。其中在扬尘过程中产生的particulate matter(颗粒物)-PM10和PM2.5,以其具有对空气质量影响大、人体损害程度强、有害物质含量多、空气滞留时间长、飘散传播距离远等危害,对人们生活和生产带来严重影响。本文总结和分析了公路工程施工过程中PM10和PM2.5的产生原因,通过研究采用排放因子测算和AP-42模型解析,针对性的提出了在公路工程施工过程中PM10和PM2.5的具体控制技术和措施。呼吁建立起施工期间排放颗粒物收费机制,将对今后公路工程施工中对PM10和PM2.5的控制起到积极的参考作用。
With the continuous development of economy and society in our country, the impact of air and environmental quality on human health has drawn increasing attention. The impact of dust generated in the highway construction process on the environment has drawn more and more researchers’ attention. Among them, the particulate matter (PM-PM10 and PM2.5) generated during the dust-lifting process is endangered by its high air quality, strong damage to the human body, high content of harmful substances, long residence time of air, Have a serious impact on people’s life and production. This paper summarizes and analyzes the causes of PM10 and PM2.5 during the construction of highway engineering. Through the study of emission factor calculation and AP-42 model analysis, the paper puts forward concretely PM10 and PM2.5 in highway engineering construction Control technology and measures. It calls for the establishment of a charging mechanism for emission of particulate matter during construction and will play a positive reference role in the control of PM10 and PM2.5 in highway construction in the future.
