摘　　要：为识别金华市典型行业挥发性有机物(VOCs)污染特征及治理方向,以金华市12个典型行业的固定污染源为研究对象,基于实测的VOCs源成分谱,建立了综合考虑排放量、臭氧反应活性(SR_(O3))及二次有机气溶胶反应活性(SR_(SOA))的污染源分级方法。结果表明:涂料制造、包装印刷和其他工业涂装行业的SR_(O3)较高,分别为2.2181、2.1222、2.0051 g/g。包装印刷、医药制造、涂料制造和其他工业涂装行业的SR_(SOA)较高,分别为0.0199、0.0132、0.0126、0.0096 g/g。其他工业涂装、包装印刷、涂料制造和医药制造的污染源归一化管控指数(NCI)较高,分别为1.00、0.82、0.64、0.56,控制这些行业关键组分的排放对VOCs总量的削减及臭氧、二次有机气溶胶的生成抑制都有作用。This study aimed to identify the pollution characteristics and management directions of volatile organic compounds(VOCs)from typical industries in Jinhua.Focusing on the stationary sources of 12 typical industries,it had established a pollution source classification method based on actual measured VOCs source profiles,taking into account of emission volumes,source reactivity of ozone(SR_(O3)),and source reactivity of secondary organic aerosol(SR_(SOA)).The results showed that the SR_(O3)of coating manufacturing,packaging and printing,and other industrial coating industries were relatively high(2.2181,2.1222 and 2.0051 g/g,respectively).The SR_(SOA) of packaging and printing,pharmaceutical manufacturing,coating manufacturing,and other industrial coating industries were relatively high(0.0199,0.0132,0.0126 and 0.0096 g/g,respectively).The pollution source normalized control index(NCI)for other industrial coating,packaging and printing,coating manufacturing,and pharmaceutical manufacturing industries were 1.00,0.82,0.64 and 0.56,respectively,indicating relatively high levels.Controlling the emissions of key components in these industries could achieve the reduction of overall emissions,along with decreased formation of ozone and secondary organic aerosol.
