中文摘要
      本文通过2105年浙江省254家包装印刷企业的调查数据,剖析了该行业原辅料组分及挥发性有机物(VOCs)污染治理现状,并筛选出100家典型企业,按印刷工艺划分阐述包装印刷行业VOCs排放特征、核算VOCs排放系数.结果表明,浙江省近2/3包装印刷企业未能有效处理VOCs,且大部分企业仍使用溶剂型原辅料,主要排放污染因子为乙酸乙酯、异丙醇、乙醇、乙酸丙酯、乙酸丁酯等9种物质.全省包装印刷行业VOCs平均排放系数为0.485 kg·kg-1,其中凹印工艺排放系数最高,为0.634 kg·kg-1.与物料衡算法计算值相比,由排放系数得到的排放量误差控制在15%以内.
英文摘要
      This paper presents the raw material composition and VOC treatment status of the packaging and printing industry in Zhejiang Province based on the survey data obtained in 2015 of 254 packaging and printing enterprises. To analyze the emission characteristics and calculate the emission coefficients of the packaging and printing industry, 100 typical enterprises were further screened according to different printing processes. The results showed that about two-thirds of packaging and printing enterprises failed to effectively dispose of VOCs; meanwhile, solvent-based materials were still commonly used in the packaging and printing industry. The main emission pollution factors of VOCs in the packaging and printing industry were ethyl acetate, isopropanol, ethanol, propyl acetate, and n-butyl acetate. The VOC emission coefficient of the packaging and printing industry in Zhejiang Province was 0.485 kg·kg-1, of which the gravure printing was the primary source with VOCs emission coefficient of 0.634 kg·kg-1. Compared with the material balance method, the error value from the emission coefficient method was less than 15%.
