沈阳市挥发性有机物减排形势分析与对策
|
摘要
通过实地调研和收集资料,对沈阳市各类VOCs大气污染物排放源进行了系统识别和分类,按照相关技术规范的要求,结合实际情况,估算得出沈阳市VOCs大气污染物排放量,并分析了排放特征。研究发现,沈阳市挥发性有机物主要来源于工艺过程源(55.02%)、溶剂使用源(16.51%)、移动源(12.7%)和生物质燃烧源(8.87%)的排放,主要涉及的行业包括:石油化工、有机化工、表面涂装、橡胶制品等。在此基础上,文章对现有VOCs治理技术进行了评估,结合沈阳市的VOCs排放特征,有针对性地提出了沈阳市VOCs污染控制对策。
By surveying and collecting the information on VOCs emission in Shenyang city,the system identification and classification of various VOCs pollutants sources in Shenyang were analyzed.According to the requirements of relevant technical specifications and the actual situation,the emissions of VOCs in Shenyang city was estimated,and the characteristics of the emission were analyzed.It was found that the main emission sources of VOCs in Shenyang were from the industrial processes source(55.02%),the solvent utilization source(16.51%),the moving source(12.7%) and biomass burning source(8.87%),which mainly include petrochemical,organicchemicals,surface coating,rubber products,and so on.Further the existing VOCs control technology was evaluated in this paper.Combined with the VOCs emission characteristics in Shenyang City,the countermeasures for VOCs pollution control were put forward pointedly.
