城市大气颗粒物污染源解析与减排路径优化研究OACHSSCD
Research on Pollution Source Analysis and Emission Reduction Path Optimization of Urban Atmospheric Particulate Matter
城市大气颗粒物污染主要来源于工业排放、交通尾气、城市扬尘、二次气溶胶及区域传输,严重威胁公众健康与生态环境.因此,要做好超低排放改造,调整交通结构,加强扬尘管控,推进前体物协同减排,强化区域联防联控.系统解析5类污染来源的排放特征,提出减排策略,并以某典型内陆工业城市为例,结合化学质量平衡模型,定量评估各措施效果.结果表明,多措协同干预组细颗粒物(PM2.5)年均质量浓度削减率约为 40.6%,综合减排成效显著.
The main sources of urban atmospheric particulate pollution are industrial emissions,traffic exhaust,urban dust,secondary aerosols and regional transport,which seriously threaten public health and ecological environment.Therefore,it is necessary to carry out ultra-low emission transformation,adjust transportation structure,strengthen dust control,promote coordinated emission reduction of precursors,and strengthen regional joint prevention and control.The emission characteristics of five types of pollution sources are systematically analyzed,the emission reduction strategies are proposed,and then taking a typical inland industrial city as an example,combined with a chemical mass balance model,the effectiveness of each measure is quantitatively evaluated.The results show that the annual average reduction rate of fine particulate matter(PM2.5)concentration in the multi measures collaborative intervention group is about 40.6%,and the comprehensive emission reduction effect is significant.
