淄博市涂装行业VOCs排放水平及减排潜力

为了评估淄博市涂装行业的挥发性有机物（VOCs）排放水平和减排潜力，对3个具有代表性的涂装行业：汽车制造涂装行业、木制家具涂装行业和金属表面涂装行业的8个典型企业展开实地调研；在此基础上采用实测法、物料衡算法和排放因子法核算企业的VOCs排放量，建立本地化排放因子，并与包括AP-42在内的国内外其他研究进行对比，评估企业排放水平；基于物料衡算法核算减排潜力；并采用显著性差异分析法研究各环节管控的影响程度.结果表明，淄博市汽车制造行业VOCs的排放因子为4.38 kg ·辆^-1，木制家具涂装行业的排放因子（以涂料计）为212.52 g ·kg^-1，金属表面涂装行业的排放因子（以涂料计）为42.79 g ·kg^-1；家具企业C的源头减排潜力及金属G和F的过程减排潜力能够达到50%以上；各环节管控的影响程度从高到低依次为：源头>过程>末端.

VOCs Emission Level and Emission Reduction Potential of Coating Industry in Zibo

To evaluate the emission level and emission reduction potential of volatile organic compounds (VOCs) in the coating industry in Zibo, we conducted field research on eight typical enterprises in three representative coating industries:the automobile manufacturing coating industry, wooden furniture coating industry, and metal surface coating industry. The actual measurement method, material balance algorithm, and emission factor method were used to calculate the VOC emissions of enterprises, and the localized emission factors were established. The emission levels of enterprises were evaluated by comparing with other domestic and foreign studies including AP-42, and the emission reduction potential was calculated based on the material balance algorithm. The significance difference analysis method was used to study the influence degree of each link management and control. The results showed that the VOC emission factor in Zibo was 4.38 kg·car^-1 for the automobile manufacturing coating industry, 212.52 g·kg^-1 paint for the wooden furniture industry, and 42.79 g·kg^-1 paint for the metal surface painting industry. The source emission reduction potential of furniture enterprise C and the process emission reduction potential of metal enterprises G and F could reach more than 50%. The degree of influence of each link management and control from high to low was source>process>end.
