| 摘 要： | 识别金属包装业挥发性有机化合物(volatile organic compounds,VOCs)产生和排放节点,定量分析不同类型生产工艺所排放VOCs的物种及含量,结合最大增量反应活性法和修正的气溶胶生成系数法对行业二次污染进行核算.结果表明,金属包装业排放的VOCs主要为苯系物、醇类、酮类和酯类,苯系物和醇类在不同类型工序和排污节点中贡献较大,酮类和酯类贡献相对较少,单物种浓度最高的VOCs为正丁醇,浓度达269.08mg·m~(-3);生产线与相应的排气筒之间VOCs物种浓度相关性较好,但物种种类存在差异;行业的O_3和二次有机气溶胶(secondary organic aerosol, SOA)生成潜势(以O_3/VOCs和SOA/VOCs计)分别为(3.09±0.94)g·g~(-1)和(2.58±1.99)g·g~(-1),苯系物和内全涂烘干工序为O_3和SOA的主要前体物和首要生成节点.

| Abstract: | This study identified the generation and emission nodes of volatile organic compounds (VOCs) in the metal packaging industry, analyzed the VOCs concentration and species from different production processes, and accounted for secondary pollution through the maximum incremental reactivity method and modified fractional aerosol coefficient method. The results indicated that the main VOCs species were benzenes, alcohols, ketones, and esters, and the benzenes and alcohols contributed more in different types of processes and emission nodes, whereas the ketones and esters contributed less. The maximum concentration was 269.08mg·m-3 (n-butanol). Strong correlation was found between the concentrations of the production line and their corresponding exhaust, but the VOC species were not totally identical. Furthermore, the potential formations of ozone and secondary organic aerosols were (3.09±0.94) g·g-1 and (2.58±1.99) g·g-1, respectively, expressed by O3/VOCs and SOA/VOCs, and the benzenes and internal coating drying being the major precursors and emission node. |
