| 以珠三角地区典型溶剂使用行业为研究对象，包括印刷业、家具制造业和电子元件及设备制造业，进行基于不同原料类型和末端治理的VOCs排放系数研究，对比研究了典型生产工艺不同类型的原料VOCs组分与含量特征，不同原料类型及末端综合治理情况对VOCs排放的影响，最终建立了三大行业典型生产工艺基于原料类型及末端综合治理情况的精细化VOCs排放系数.结果表明，印刷业有机原料中VOCs组分主要为乙酸乙酯、乙酸丙酯、异丙醇、正丙醇和乙醇等含氧VOCs，其占比约为原料总VOCs的60%~80%；家具制造业有机原料中含氧VOCs主要为乙酸乙酯和乙酸丁酯，占比约为原料总VOCs的45%~65%；电子元件和设备制造业有机原料VOCs组分主要为醇、醚、酚等含氧VOCs，苯系物及卤代烃等.印刷业VOCs治理前后综合排放系数分别为415.2 kg·t-1和184.3 kg·t-1.其中，溶剂型原料为704.9 kg·t-1和200.1 kg·t-1，水溶性原料为325.6 kg·t-1和230.3 kg·t-1，UV型原料为197.0 kg·t-1和129.0 kg·t-1，植物型原料为89.0 kg·t-1和89.0 kg·t-1.家具制造业VOCs治理前后综合排放系数分别为379.0 kg·t-1和290.2 kg·t-1.其中，溶剂型原料为603.0 kg·t-1和448.5 kg·t-1，水溶性原料为80.0 kg·t-1和80.0 kg·t-1，粉末型原料为230.0 kg·t-1和184.0 kg·t-1.电子元件及设备制造中，AC陶瓷电容器、CC陶瓷电容器、压敏电阻、铝电解电容器治理前后VOCs排放系数［单位：kg·（百万只）-1］分别为59.7和40.8、394.1和269.6、282.4和193.2、1.2和1.0.连续端子、漆包线和PCB印制电路板治理前后VOCs排放系数分别为56.3 kg·t-1和42.8 kg·t-1、87.2 kg·t-1和28.3 kg·t-1、26.4 kg·（100 m2）-1和11.6 kg·（100 m2）-1. |

| A database of refined raw materials and end treatment-based VOCs emission factors for typical solvent use sources was developed for the Pearl River Delta. For this, the impact of composition and the content of raw materials, production process, and comprehensive end treatment on the emission of VOCs was analyzed. The solvent use sources included printing, furniture manufacturing, and electronic component and equipment manufacturing. The results showed that the main VOCs in the raw materials used in printing were ethyl acetate, propyl acetate, isopropanol, propanol, and ethanol, which contributed 60%-80% to the total amount of VOCs. Ethyl acetate and butyl acetate were the main oxygenated VOCs (OVOCs) from the raw materials used in furniture manufacturing, contributing 45%-65% of the total. The main VOCs from the raw materials used in electronic component and equipment manufacturing were OVOCs such as alcohols, ethers and phenols, BTEX, and halohydrocarbons. The uncontrolled and controlled emission factors for VOCs from printing were 415.2 kg·t-1 and 184.3 kg·t-1, respectively. Of these, solvent-based raw materials accounted for 704.9 kg·t-1 and 200.1 kg·t-1, water-based raw materials accounted for 325.6 kg·t-1 and 230.3 kg·t-1, UV raw materials accounted for 197.0 kg·t-1 and 129.0 kg·t-1, and plant-based raw materials accounted for 89.0 kg·t-1 and 89.0 kg·t-1, respectively. The uncontrolled and controlled emission factors for VOCs from furniture manufacturing were 379.0 kg·t-1 and 290.2 kg·t-1, respectively. Of these, solvent-based raw materials accounted for 603.0 kg·t-1 and 448.5 kg·t-1, water-based raw materials accounted for 80.0 kg·t-1 and 80.0 kg·t-1, and powder raw materials accounted for 230.0 kg·t-1 and 184.0 kg·t-1, respectively. In electronic component and equipment manufacturing, the uncontrolled and controlled emission factors (unit:kg·million-1) for VOCs from AC ceramic capacitors, CC ceramic capacitors, varistors, and aluminum electrolytic capacitors were 59.7 and 40.8, 394.1 and 269.6, 282.4 and 193.2, and 1.2 and 1.0, respectively. The uncontrolled and controlled emission factors for VOCs from the manufacturing of continuous terminals, enameled wire, and printed circuit boards were 56.3 kg·t-1 and 42.8 kg·t-1, 87.2 kg·t-1 and 28.3 kg·t-1, and 26.4 kg·(100 m2)-1 and 11.6 kg·(100 m2)-1, respectively. |
