摘　　要：采用罐采样-GC-MS/FID分析方法对某再生橡胶厂不同工艺过程无组织排放VOCs的浓度水平及组分特征进行研究。结果表明,再生橡胶生产过程中芳香烃和OVOCs是主要的VOCs排放组分,其中以丙酮和苯系物为主,脱硫和冷却过程为主要的排污环节。丙酮、4-乙基甲苯和间二甲苯在各环节的占比都较大,可作为该行业的标志物。芳香烃为冷却堆场和开炼精炼环节中主要的VOCs组分,丙酮为脱硫和冷却环节中排放的主要物质。与不同行业的研究进行对比,再生橡胶行业排放的废气中芳香烃占比更大,同时也是OFP贡献最大的组分应受到重视。The levels and compositions of VOCs emitted from the rubber reclaiming processes in a county,Shanxi province,were studied using the GC-MS/FID of canister sampling method. Aromatics and OVOCs,which mainly include acetone and benzene,are major components of VOCs in the rubber reclaiming processes. The desulfurization and cooling process were the main pollutant processes. Acetone,4-ethyltoluene and m-xylene,which are typical characteristics in this industry,have a great proportion in these processes. Aromatics are the main compositions of VOCs in cooling yard,mixing mill and refining mill and acetone are the main emission during the desulfurization and cooling processes. The proportion of aromatic hydrocarbons in exhaust released from the reclaimed rubber industry are larger than that in other industries. Meanwhile,aromatic hydrocarbons are also the largest contributions of OFP. Thus,that should be given with due attention.
