摘要
VOCs质谱走航监测结果表明,高新区工业企业VOC污染组分以烷烃、烯烃和芳香烃为主,不同类型企业VOCs污染主要组分略有不同。VOCs污染主要来源以企业生产过程包装、喷涂、印刷等环节逸散和原辅材料随意堆放挥发为主;建筑工地露天焊接、刷漆挥发逸散、机动车排放及管道泄漏等对于VOCs污染也有一定贡献。建议从加强VOCs“无组织排放”管控、优化VOCs质谱走航监测系统及开展VOCs污染防控工作考核等方面开展工业企业VOCs污染防控工作。
The monitoring results of VOCs mass spectrometry show that the VOC pollution components of industrial enterprises in the high-tech zone are mainly alkanes,olefins and aromatic hydrocarbons,and the main components of VOCs pollution of different types of enterprises are slightly different.The main sources of VOCs pollution are the fugitives from packaging,spraying,printing and other links in the production process of enterprises and the volatilization of raw and auxiliary materials;open-air welding,paint evaporation and escape from construction sites,motor vehicle emissions and pipeline leakage also contribute to VOCs pollution.It is recommended to carry out the prevention and control of VOCs pollution in industrial enterprises from the aspects of strengthening the control of “unorganized emissions” of VOCs,optimizing the VOCs mass spectrometry navigation monitoring system,and carrying out the assessment of VOCs pollution prevention and control.
