摘　　要：根据"源头追踪"思路,结合生产工艺调查,现场采样及实验分析,研究了漆包线制造过程中挥发物有机物(VOCs)从原物料输入到产品输出(原物料输入、净化销毁、泄露、逸散、最终排放、产品残留)各环节的排放特征.结果表明,共检出41种VOCs,从原物料输入的VOCs,有81.1%得到了销毁,3.5%从涂料储槽,供漆系统等环节逸散,2.6%从炉膛出口及其他环节泄露,8.4%经管道有组织排放,只有极少部分残留在产品中.主要排放的VOCs成分是乙苯、甲酚、二甲酚、苯酚、二甲苯、N-甲基吡咯烷酮、二甲基甲酰胺.VOCs排放系数为(24.75±6.52)g VOCs/kg漆包线.采用排放系数法估算了2010年全国漆包线行业VOCs的排放量和2015年的预期排放量分别为2.62万t和3.19万t.The emission characteristics of volatile organic compounds（VOCs） from raw materials input to products output（raw materials input,destruction,leakage,fugacity,final emission,products output） were studied in enameled wires manufacturing processes based on the concept of source-tracing,production process investigations,on-site sampling and experimental analysis.The results showed that 41 kinds of VOCs were detected,81.1% VOCs from raw materials were destroyed,3.5% escaped from paint storage tank,paint supply system,etc.2.6% leaked from furnace outlet and other links,8.4% emitted from organized emission pipes,only few were remain in products.The main emitted constituents of VOCs were ethyl benzene,methyl phenol,dimethyl phenol,phenol,dimethyl benzene,NMP,DMF.The emission factor was（24.75±6.52） g VOCs/kg enameled wires.The emission of VOCs from enameled wire manufactures in the year 2010 was 2.62 million tons and it would reach 3.19 millon tons in the year 2015 were estimated by emission factor method.
