摘　　要：在华北地区选取典型有机溶剂使用行业开展基于不同生产环节和有机溶剂类型的挥发性有机物(VOCs)样品采集和117种VOCs组分分析。结果表明:1)印刷和金属表面涂层企业不同生产环节中,印刷、喷涂环节的VOCs浓度最高。2)印刷企业VOCs以含氧挥发性有机物(OVOCs)为主,占比(质量分数)为18.0%~99.6%。水性油墨车间特征组分为异丙醇、甲基丙烯酸甲酯、1-己烯,溶剂型油墨车间特征组分为乙醇、乙酸乙酯和甲基环己烷。金属表面涂层企业以OVOCs和芳香烃为主,占比分别为4.6%~82.1%和9.1%~70.1%。水性涂料组分主要有1,2-二氯乙烷、1,2-二氯丙烷、间/对二甲苯。溶剂型涂料特征组分为间/对二甲苯、乙醇和乙苯;末端处理设施紫外线(UV)光氧催化和催化燃烧装置分别对乙醇和间/对二甲苯去除效果较好。3)印刷企业对臭氧生成潜势(OFP)贡献大的VOCs组分为OVOCs,平均占比73.3%,高活性组分主要有乙醇、乙酸乙酯和异丙醇,金属表面涂层企业对OFP贡献大的VOCs组分为芳香烃,平均占比48.5%,高活性组分主要为间/对二甲苯、乙苯和甲苯。各环节对比源反应活性(SR)差异显著,VOCs的UV光氧催化治理工艺会导致印刷和金属表面涂层企业SR大于生产环节。Volatile organic compounds(VOCs)samples were collected and 117 VOCs components were studied based on various production processes and types of organic solvents in typical solvent-using industries in North China.The results showed that:1)The printing and coating processes had the greatest concentration of VOCs among different production segments in the printing and metal surface coating enterprises.2)In the printing enterprises,VOCs were dominated by oxygenated volatile organic compounds(OVOCs),accounting for 18.0%to 99.6%(mass fraction).Ethanol,methyl methacrylate,and ethyl acetate were the main VOCs components in water-based ink workshop,while ethanol,ethyl acetate and methyl cyclohexane were the main species in the solvent-based ink workshop.The main VOCs emitted by metal surface coating enterprises were OVOCs and aromatic hydrocarbons,accounting for 4.6%-82.1%and 9.1%-70.1%,respectively.1,2-dichloroethane,1,2-dichloropropane,m/p-xylene were the main VOCs species in the water-based coating workshop,while the solvent-based coating workshop was m/p-xylene,ethanol and ethylbenzene.Ultraviolet(UV)photo-oxidation catalytic and catalytic combustion treatment facilities were better for ethanol and m/p-xylene elimination,respectively.3)Ozone formation potential(OFP)in the printing sector was mostly affected by OVOCs,which contributed an average of 73.3%.Highly reactive species included ethanol,ethyl acetate,and isopropanol.In the metal surface coating sector,aromatic hydrocarbons constituted the majority of OFP,accounting for 48.5%on average.The highly reactive species were mostly m/p-xylene,ethylbenzene,and toluene.Source reactivity(SR)of different segments varied significantly.The SR for the printing and metal surface coating enterprises may increase more than that in the workshop as a result of the UV photo-oxidation catalytic treatment.
