摘 要:基于2019—2022年监测数据,对石家庄市VOCs组成、污染特征、臭氧生成潜势(OFP)进行分析,筛选VOCs关键活性组分,提出针对性的污染防控策略。结果表明,石家庄市大气中总VOCs年均污染浓度为85.66μg/m^(3),卤代烃、烷烃和芳香烃是主要构成类别;OFP年均值为125.53μg/m^(3),其中卤代烃贡献最大,其次为芳香烃、烯烃。对OFP贡献值较大的10种关键前体物依次为间/对-二甲苯、1,3-丁二烯、氯乙烯、反式-1,3-二氯丙烯、顺式-1,2-二氯乙烯、丙烯、六氯丁二烯、甲苯、邻二甲苯、三氯乙烯。VOCs优先控制种类为芳香烃,主要来源于制药、石油化工和溶剂使用源。应通过推进源头减排、无组织排放管控、末端治理等全过程精细管理,提高自动监控水平,完善协同控制、联防联控等手段进行污染防控。Based on the monitoring data from 2019 to 2022,this paper analyzed the composition,pollution characteristics and ozone formation potential(OFP)of VOCs in Shijiazhuang.Key reactive components were identified and targeted pollution control strategies were proposed.The results showed that the average annual concentration of total VOCs in Shijiazhuang was 85.66μg/m^(3),and halogenated hydrocarbons,alkanes and aromatic hydrocarbons were the main components.The annual average value of OFP was 125.53μg/m^(3),with halogenated hydrocarbons contributing the most,followed by aromatic hydrocarbons and olefins.The 10 key precursors with large contributions to OFP were m/p-xylene,1,3-butadiene,vinyl chloride,trans-1,3-dichloropropylene,cis-1,2-dichloroethylene,propylene,hexachlorobutadiene,toluene,o-xylene,and trichloroethylene.The priority control species of VOCs are aromatic hydrocarbons,which mainly come from pharmaceutical,petrochemical and solvent sources.Pollution prevention and control should be carried out by promoting the fine management of the whole process such as source emission reduction,containment of fugitive emission,and end treatment,improving the level of automatic monitoring,and improving collaborative control and joint prevention and control.
