摘　　要：通过苏玛罐采样和GC-MS/FID分析系统,测定了山东地区典型胶合板制造企业的VOCs排放特征.结果表明,烷烃(13.81%~39.16%)、含氧VOCs(5.68%~36.06%)和芳香烃(3.58%~48.12%)是热压和涂胶工艺主要排放成分,废气排口以含氧VOCs(6.49%~83.88%)排放为主,不同工艺环节的特征VOCs组分各有不同;烯炔烃(27.12%~39.38%)和芳香烃(32.47%~45.63%)是热压工艺和涂胶工艺的高OFP组分,废气排口则以含氧VOCs(52.82%)对O3生成贡献最大;基于SOAP评估,各环节均以芳香烃类化合物(97.08%~98.03%)为主要活性组分;测得山东地区胶合板制造行业VOCs排放因子为0.89g VOCs/m^3胶合板.VOCs emission characteristics of typical plywood industry in Shandong were determined using SUMMA canister-GCMS/FID analysis system.The results showed that alkanes(13.81%~39.16%),oxygenated VOCs(5.68%~36.06%)and aromatics(3.58%~48.12%)were the main emission components of hot pressing and gluing processes,while exhaust gas discharges were dominated by oxygenated VOCs(6.49%~83.88%).The characterized VOC emissions compositions in each process were different;alkenes and alkynes(27.12%~39.38%)and aromatics(32.47%~45.63%)were the high OFP components of hot pressing and gluing process,and oxygenated VOCs(52.82%)in the exhaust gas discharge contributed the most to O3 generation.Based on the SOAP evaluation,aromatics(97.08%~98.03%)were the main active components in all processes;also,the emission factor of VOCs in the Shandong plywood manufacturing industry was measured to be 0.89 g VOCs/m^3 plywood.
