摘　　要：为掌握农药制剂加工行业挥发性有机物(VOCs)污染特征及其环境影响,选取典型农药制剂加工企业为研究对象,研究了农药制剂加工企业的VOCs排放特征,并使用最大增量反应活性(MIR)法计算了不同生产环节排放VOCs对臭氧生成的贡献。结果表明,不同生产环节排放废气中VOCs的组分存在一定的差异,含氧VOCs(13.4%~97.7%)、芳香烃(0.2%~73.0%)和卤代烃(0.1%~51.7%)为农药制剂加工企业的主要VOCs组分,甲醇、1,2-二氯乙烷、二氯甲烷、二甲苯和乙醇为主要VOCs物种;农药制剂加工企业VOCs中对臭氧生成潜势贡献率较大的关键活性组分为含氧VOCs(6.7%~94.4%)和芳香烃(1.3%~91.7%),间/对-二甲苯、邻-二甲苯、甲苯、乙苯和甲醇等是农药制剂加工企业的关键活性物种。为满足对农药制剂加工企业VOCs的减排要求,需要大力推广环保农药剂型,优化废气收集系统,提升废气处理工艺,加强对甲醇等溶剂的回收处理。To grasp the characteristics of volatile organic compounds(VOCs)pollution in the pesticide formulations industry and associated environmental impacts,a typical pesticide formulations enterprise was selected as the research object.The VOCs emission characteristics of the pesticide formulations enterprise were studied,and the Maximum Incremental Reactivity(MIR)method was used to calculate the contribution of VOCs from different production processes to ozone generation.The results showed that there are certain differences in VOCs components in exhaust gases emitted from different production processes.Oxygencontaining VOCs(13.4%~97.7%),aromatic hydrocarbons(0.2%~73.0%),halogenated hydrocarbons(0.1%~51.7%)were the main VOCs components in the pesticide formulation enterprise.And methanol,1,2-dichloroethane,dichloromethane,xylene and ethanol were the main VOCs species.The key active components of VOCs greatly contribution to the ozone generation potential in the pesticide formulation enterprise were oxygen-containing VOCs(6.7%~94.4%)and aromatic hydrocarbons(1.3%~91.7%).M/pxylene,o-xylene,toluene,ethylbenzene and methanol were the key active species in the pesticide formulations enterprise.To meet the emission reduction requirements of VOCs in pesticide formulations enterprises,it is necessary to vigorously promote environmentally friendly pesticide formulations,optimize waste gas collection systems,improve waste gas treatment processes,and strengthen the recovery and treatment of solvents such as methanol.
