摘要
使用SUMMA罐采集华东地区5类典型合成树脂企业有组织排口样品,通过气相色质联用技术(GC-MS)定量分析106种VOCs,计算了合成树脂行业排放量、排放系数和不确定性,分析了VOCs的排放特征和臭氧生成潜势,建立了5类合成树脂VOCs排放成分谱.结果表明:合成树脂企业VOCs排放量为346~3467kg/a,5类合成树脂排放系数为0.06~1.24g/kg,其中涂料树脂(CR)类企业排放量和排放系数均最大.芳香烃、含氧烃(OVOCs)和卤代烃是合成树脂行业VOCs排放基本组分,累计占比范围是73.2%~98.3%.涂料树脂、酚醛树脂(PF)、聚氨酯(PU)、共聚物树脂(ABS)和聚碳酸酯(PC)特征污染物分别为:甲基异丁基酮、苯、甲苯、苯乙烯和二氯甲烷.合成树脂企业臭氧生成潜势(OFP)为22.7~202.5mg/m^3,源反应性(SR)为0.3~4.6g/g,CR类企业OFP和SR均最大.合成树脂行业SR处于各行业平均水平.芳香烃、OVOCs和烯炔烃是合成树脂行业的主要光化学活性组分,累计OFP贡献率为64.1%~100.0%,苯、甲苯、甲基异丁基酮、乙烯、苯乙烯是合成树脂行业关键活性物种.研究显示,合成树脂行业VOCs治理应管控芳香烃和OVOCs的排放,重视污染物恶臭问题和卤代烃溶剂的危害,减排VOCs排放量大、臭氧生成能力强的CR类企业.
Gas samples were collected with SUMMA canisters from five typical synthetic resin enterprises located in East China.A total of 106 volatile organic compounds(VOCs)in samples were determined by gas chromatography-mass spectrometry(GC-MS).The total emissions and emission coefficients of the synthetic resin industry were calculated,the uncertainty was also analyzed.The emission characteristics were described,and ozone formation potential(OFP)of VOCs were analyzed and the source profiles of five synthetic resins were established.The results showed that the VOCs emissions of synthetic resin enterprises were 346~3467kg/a,and the emission coefficients of five synthetic resins ranged from 0.06 to 1.24g/kg.Among them,the coating resin(CR)enterprises had the largest emission and emission coefficients.Aromatic hydrocarbons,oxygenated hydrocarbons(OVOCs)and halogenated hydrocarbons were characteristic components of VOCs in the synthetic resin industry,the cumulative concentration ranged from 73.2%to 98.3%.The main VOCs pollutants from coating resin(CR),phenol resin(PF),polyurethane(PU),acrylonitrile-butadiene-styrene copolymer(ABS)and polycarbonate(PC)were methyl isobutyl ketone,benzene,toluene,styrene and dichloromethane,respectively.The ozone formation potential(OFP)of the synthetic resin enterprises ranged from 22.7 to 202.5mg/m3,and the source reactivity(SR)ranged from 0.3 to 4.6g/g.The OFP and SR of CR enterprises were the largest in five synthetic resins.The SR of the synthetic resin industry was at an average level among industries.Aromatic hydrocarbons,OVOCs and alkynes were the main active components in the synthetic resin industry,with a total contribution to the OFP ranging from 64.1%to 100.0%.The major contributors of synthetic resin industry were benzene,toluene,methyl isobutyl ketone,ethylene,and styrene.Our study showed that VOCs pollution control in the synthetic resin industry should focus on aromatic hydrocarbons and OVOCs,extra attention should be paid to the of pollutant odors and halogenated hydrocarbon
