| 摘 要： | 为更好地掌握北京市电子工业挥发性有机物（VOCs）排放特征及其与其他溶剂使用行业的排放差异，为工业结构调整提供启发和建议，通过实际监测，识别电子工业有组织和无组织VOCs排放水平，采用产污系数法并结合集气效率和去除效率，核算得到2019年北京市电子工业VOCs排放量及各子行业的排放贡献，并与其他典型溶剂使用行业的VOCs排放强度进行了对比.结果表明:电子工业VOCs产生主要集中在光刻、清洗、剥离、显影等环节，使用的有机溶剂主要包括光刻胶、稀释剂、清洗剂和去除剂，分别约占3%、81%、6%和10%，其中约16%以废气形式排入大气.核算得到2019年北京市电子工业VOCs排放量为1 542 t，主要来自显示器件和集成电路行业，分别贡献了71%和18%，与其产量和有机溶剂使用量较大有关，电子专用材料制造和其他行业则分别贡献了3.2%和7.8%.通过与其他典型溶剂使用行业排放强度对比发现，电子工业单位产值VOCs排放强度较低，是家具制造、印刷等传统溶剂使用行业的1/2 750和1/3 250，说明北京市工业结构调整和优化对于减少污染排放具有重要作用.研究显示，可综合城市发展及经济水平，逐步限制发展高排放工业类别，鼓励发展如电子工业等技术密集型和附加值高的行业类别，从而促进城市空气质量的改善.

| Abstract: | In order to better understand the VOCs emission characteristics of electronics industry in Beijing and provide inspiration and suggestions for industrial structure adjustment, the organized and unorganized VOCs emission of electronics industry was determined through actual monitoring. Combining emission factor method and efficiency of exhaust gas collection and control technology, the VOCs emissions of electronics industry in Beijing and the contribution of each sub-industry in 2019 were determined and compared with the other solvent-using industries. The results showed that VOCs production in the electronics industry mainly came from lithography, cleaning, stripping, and development. The organic solvents mainly included photoresist, thinner, cleaning agent, and remover, accounting for about 3%, 81%, 6% and 10%, respectively. 16% of the organic gas was discharged into the atmosphere. According to calculations, the VOCs emissions of Beijing's electronics industry in 2019 was 1542 t, mainly from the display device and integrated circuit industries, which contributed 71% and 18% the emissions, respectively, which was related to the output and the high usage of organic solvents. Electronic special materials manufacturing and other industries contributed 3.2% and 7.8% of the emissions, respectively. Compared with the emission intensity of other typical solvent-using industries, the VOCs emission intensity of the electronics industry was relatively low, which is 1/2750 and 1/3250 of the traditional solvent-using industries such as furniture and printing, indicating that the adjustment and optimization of industrial structure in Beijing played an important role in air quality improvement. According to the research, integrating urban development and economic levels, gradually restricting the development of high-emission industrial categories, and encouraging the development of technology-intensive and high-value-added industries such as the electronics industry will promote the improvement of urban air quality. |
