摘　　要：为研究标准件行业VOCs排放特征及其环境影响,选取了典型标准件企业进行现场调研与采样,运用GC-MS/FID测定了废气中102种VOCs物种,建立了标准件行业VOCs源成分谱,并估算了行业VOCs的环境污染影响、排放因子及排放量.结果表明,标准件行业各工序VOCs均以烷烃(29.58%~68.94%)为主要排放组分.正十二烷、乙烷、丙烷等烷烃,邻-二甲苯、对二甲苯等芳香烃,乙酸丁酯、乙醛等含氧VOCs为该行业高排放物种.芳香烃是该行业臭氧生成潜势的主要贡献组分,烷烃是该行业二次有机气溶胶生成潜势的主要贡献组分.标准件行业VOCs排放因子为1.51kg/t,2018~2020年全国标准件行业VOCs排放量分别为11496.84,13301.89,14365.69t,年均增长率为11.85%,其排放以华北和华东地区为主,两地区排放量累计占比范围为84.55%~89.08%.In order to study the VOCs emissions characteristics of fastener industry and its impact on air quality, typical industries were selected and a sampling project was conducted. 102 species of VOCs were analyzed utilizing GC-MS/FID. The VOC spectrums of fastener industries were established. The emission inventory, emission factors and its impact on air quality were estimated. Results indicated that the alkane was the dominant component of VOCs in all processes of fastener industries with proportions ranging from 29.58% to 68.94%. Alkanes including n-dodecane, ethane and propane, aromatic hydrocarbons including o-xylene and p-xylene, and oxygenated hydrocarbons including butyl acetate and acetaldehyde were the components with high emission load. Aromatics were the major contributors to the potential of ozone generation, while alkanes were the main contributor to the formation potential of secondary organic aerosols. The VOCs emission factor of the fastener industry was 1.51 kg/t. The national annual VOCs emissions of fastener industry from 2018 to 2020 were 11, 496.84, 13, 301.89 and 14,365.69 tons in respective, with the annual growth rate of 11.85%.
