摘要

摘要: 对北京地区27家汽修企业进行调研，选取2家典型汽修企业进行气袋采样-GC-MS-FID采集及分析，定量分析其VOCs的排放特征，并计算其臭氧生成潜势（OFP）。结果表明：使用不同漆料的汽修企业排放特征不同，水性漆企业非甲烷总烃的排放浓度为0.62~36.49 mg/m³，油性漆企业的排放浓度为0~100.39 mg/m³；水性漆排放的VOCs以烷烃为主，占比高达57.16%，丙烷（39.65%）和甲苯（11.41%）是首要污染物；卤代烃（55.51%）是油性漆企业的主要VOCs排放物种，主要组分为1，2-二氯丙烷和1，2-二氯乙烷；水性漆企业的OFP值为144.78 mg/m³，油性漆企业的OFP值为664.43 mg/m³，大气反应活性最大的物种多为芳香烃，芳香烃对OFP的贡献率分别为52.18%和88.44%。

Abstract: Through the investigation of 27 auto repair enterprises in Beijing, two typical auto repair enterprises were selected to collect and analyze using the method of air bag sampling-GC-MS-FID, in order to quantitatively analyze the emission characteristics of VOCs, and calculate the ozone generating potential (OFP). The result showed that the emission characteristics of steam repair enterprises using different paints were different. The emission concentration of non-methane total hydrocarbons in water-based paint enterprises was between 0.62~36.49 mg/m³, and the discharge concentration range of oil paint enterprises was 0~100.39 mg/m³. The VOCs emitted by water-based paints were mainly alkanes, accounting for 57.16% of total VOCs, and propane (39.65%) and toluene (11.41%) were primary pollutants. Halogenated hydrocarbon (55.51%) was the main VOCs emission species of oil paint enterprises, and its main components were 1,2-dichloropropane and 1,2-dichloroethane. The OFP of water-based paint enterprises was 144.78 mg/m³, and the oil-forming paint company’s OFP was 664.43 mg/m³. Most of the atmospheric reactive species were aromatic hydrocarbons. The contribution rates of aromatic hydrocarbons to OFP were 52.18% and 88.44%, respectively.
