| 摘要: |
| 收集150家江苏省典型汽车零部件企业VOCs排放信息，对2家典型企业进行排放测试，分析江苏省该行业原辅料使用情况、产排污环节与核查要点、VOCs的排放特征，并提出最佳治理建议。研究表明，江苏省汽车零部件行业使用的涂料以溶剂型为主（占比约为79%）。废气按排放量大小依次为苯类、醇类、酯类和酮类，使用燃烧法处理后排放物种以烷烃为主，使用活性炭吸附法处理前后物种差异较小。吸附浓缩+燃烧组合处理工艺为目前最佳组合技术，处理效率＞95%。 |

| Abstract: |
| The emission information of 150 typical auto parts enterprises in Jiangsu Province was collected. The emission tests of two typical enterprises were conducted. The VOCs emission characteristics，the use of raw materials and auxiliary materials, production and sewage links and verification points were analyzed, and feasible pollution control technologies were proposed. The results showed that the proportion of solvent based coatings used by auto parts manufacturers in Jiangsu Province was about 79%. The exhaust gas mainly includes benzene series,alcohols, esters and ketones in order of emission. The exhaust gas components treated by the combustion method was mainly alkane. The species difference before and after treatment with activated carbon adsorption is small. The adsorption concentration and combustion combination treatment process is the best combination technology, and the treatment efficiency is above 95%. |
