摘要
持续推进关中地区VOCs精细化管控,以西安市和咸阳市为代表,选取包装印刷、电子产品制造、工业涂装、涂料及油墨制造、家具制造和橡胶制品6个行业进行样品采集,研究关中地区典型行业VOCs排放源成分谱、臭氧生成潜势(OFP)和二次气溶胶生成潜势(SOAFP).结果表明:包装印刷和工业涂装行业主要排放VOCs为含氧挥发性有机物(OVOCs)(53%~73%)和烷烃(17%~34%);电子产品制造行业为OVOCs(68%)和烯烃(29%);涂料及油墨制造行业以OVOCs(61%)和芳香烃(22%)为主;家具制造行业以芳香烃(78%)和OVOCs(19%)为主;橡胶制品行业以烷烃(78%)为主.其中乙醇、丙酮、异丙醇、甲醛、乙酸乙酯、间/对-二甲苯为关中地区典型行业排放的主要特征物种.基于最大增量反应活性法(MIR)和气溶胶生成系数法(FAC),得出OVOCs、芳香烃和烯烃是OFP的主要来源,芳香烃是SOAFP的主要来源,主要排放来源为涂料及油墨制造、工业涂装和家具制造行业应重点管控.
P_(2.5) control in the Guanzhong region has achieved significant progress,but the situation regarding ozone pollution remains severe.To continue advancing the fine management of VOCs(volatile organic compounds)in the Guanzhong region,with Xi'an and Xianyang as representatives,six industries—packaging printing,electronic product manufacturing,industrial coatings,paint and ink manufacturing,furniture manufacturing,and rubber products—were selected for sample collection.This study examines the VOC emission profiles,ozone formation potential(OFP),and secondary aerosol formation potential(SOAFP)of typical industries in the Guanzhong region.The results show that in the packaging printing and industrial coating industries,the primary VOCs emitted are oxygenated volatile organic compounds(OVOCs)(53%~73%)and alkanes(17%~34%);in the electronic product manufacturing industry,they are OVOCs(68%)and alkenes(29%);in the paint and ink manufacturing industry,the main VOCs are OVOCs(61%)and aromatic hydrocarbons(22%);in the furniture manufacturing industry,the primary VOCs are aromatic hydrocarbons(78%)and OVOCs(19%);and in the rubber products industry,alkanes(78%)dominate.Key characteristic species emitted by typical industries in the Guanzhong region include ethanol,acetone,isopropanol,formaldehyde,ethyl acetate,and m-/p-xylene.Based on the Maximum Incremental Reactivity(MIR)method and the Aerosol Formation Coefficient(FAC)method,it was found that OVOCs,aromatic hydrocarbons,and alkenes are the main contributors to OFP,while aromatic hydrocarbons are the primary source of SOAFP.The major emission sources are the paint and ink manufacturing,industrial coatings,and furniture manufacturing industries,which should be prioritized for control.
