摘　　要：为研究汾渭平原运城市家具制造业VOCs排放特征,选取运城市一家具有代表性的家具制造企业作为研究对象,利用气相色谱-质谱/氢火焰离子化检测器(GC-MS/FID),采用外标法定量分析了挥发性有机物(VOCs)浓度排放特征,并估算了其臭氧生成潜势(OFP)与二次有机气溶胶生成潜势(SOAFP).研究显示,底漆车间、修色车间、面漆车间、木材加工车间、厂房外、排放烟囱A以及排放烟囱B的TVOCs浓度在1.25—14.56 mg·m^(−3),烟囱A和B采用水过滤+活性炭吸附工艺对末端烟气进行处理,该工艺对烟囱A各VOCs组分具有较好的处理效果;该家具制造厂排放的主要VOCs组分为芳香烃、OVOCs和烷烃,占比分别为39.0%—68.0%、13.0%—30.0%和10.0%—28.0%,其中,主要物种为乙苯、间/对二甲苯、乙酸乙酯等;对OFP贡献较大的组分为芳香烃,占比为68.70%—93.28%,其次是OVOCs和烷烃,占比在2.82%—17.09%,对OFP贡献较大的前3种物质分别为间/对二甲苯、邻二甲苯、乙苯;SOAFP的绝对贡献者是芳香烃,占比为93.10%—98.73%,对SOAFP贡献较大的前4种物质分别为间/对二甲苯、邻二甲苯、甲苯、癸烷.因此,运城市该家具制造企业需要加强对芳香烃等活性较高的VOCs组分的监管与控制力度,希望该研究可以为其提供一定的指导意义.In order to study the VOCs emission characteristics of furniture manufacturing industry in Yuncheng City of Fenwei Plain,a representative furniture manufacturing enterprise in Yuncheng city was selected as the research object,and the emission characteristics of volatile organic compounds(VOCs)were quantitatively analyzed by using gas chromatogenic-mass spectrometry/hydrogen flame ionization detector(GC-MS/FID)and external standard method.The ozone formation potential(OFP)and secondary organic aerosol formation potential(SOAFP)were estimated.According to the study:The concentration of TVOCs,including the primer workshop,color repair workshop,finish paint workshop,wood processing workshop,outside the workshop,discharge chimney A and discharge chimney B was 1.25—14.56 mg·m^(−3).The end flue gas was treated by water filtration+activated carbon adsorption process in chimney A and B,which had a good treatment each VOCs component of chimney A.The main VOCs emitted by the furniture factory can be divided into aromatic hydrocarbons,OVOCs and alkanes,accounting for 39.0%—68.0%,13.0%—30.0%and 10.0%—28.0%,respectively,among which,the main species were ethylbenzene,m-paraxylene,ethyl acetate,etc.The group with high contribution to OFP was divided into aromatic hydrocarbons,accounting for 68.70%—93.28%,followed by OVOCs and alkanes,accounting for 2.82%—17.09%.The top three substances with high contribution to OFP were m/p-xylene,o-xylene and ethylbenzene,respectively.The absolute contributors of SOAFP were aromatic hydrocarbons,accounting for 93.10%—98.73%,and the top four substances that contribute more to SOAFP are m-paraxylene,o-xylene,toluene and decane,respectively.Therefore,more attentions should be pay for the furniture manufacturing enterprise to supervision and control of VOCs components,especially for the high activity such as aromatic hydrocarbons.
