摘要:
于2015年10月对上海市嘉定区4家(A、B、C、D)汽车制造企业涂装废气ρ(VOCs)和组成特征进行了调查分析。结果表明,A、B、C、D厂涂装废气排放口ρ(VOCs)为0.743~6.11 mg/m3,主要检出物和最高检出值分别为:A厂二甲苯2.06 mg/m3、B厂二甲苯0.578 mg/m3、C厂甲苯2.59 mg/m3、D厂庚烷0.274 mg/m3;芳香烃类是A、B、C厂排放比例最高的VOCs组分,烷烃类是D厂排放比例最高的VOCs组分。指出,原、辅料种类影响排放物的主要成分,废气处理工艺类型影响排放物主要成分和浓度。

Abstract:
A survey on the concentration and composition characteristics of VOCs from coating exhaust gas of 4 automobile manufacturers(A,B,C,D)in Jiading District of Shanghai in Oct 2015 had been carried out.In the painting workshops, concentrations of total VOCs were 0.743~6.11 mg/m3. Main compositions of VOCs for A were xylene, with the concentration of 2.06 mg/m3, for B were xylene, with the concentration of 0.578 mg/m3,for C were methylbenzene, with the concentration of 2.59 mg/m3,for D were heptane, with the concentration of 0.274 mg/m3.Aromatic hydrocarbons accounted for the highest proportion of VOCs from A, B, C,while alkanes were the dominant VOCs from D. According to the analysis of raw and auxiliary materials and production technology, it shows the types of raw materials affect the main component and the concentration of the emissions.
