| 中文摘要 |
| 根据2016年收集的秦皇岛全市609家工业企业的产品产量、原料使用量、挥发性有机物（VOCs）排放浓度、排放流量、排放方式等活动水平数据，采用直接测量法和排放因子法建立秦皇岛市工业源VOCs排放清单，结果表明，秦皇岛市全年的工业源VOCs排放总量为8420.07 t，其中，经济技术开发区为秦皇岛市VOCs排放的主要区域，VOCs排放量为4120.51 t，占总排放量的48.9%；石油加工、炼焦和核燃料加工业，化学原料和化学制品制造业是秦皇岛重点VOCs排放的主要行业，分别占总排放量的30.35%和14.42%；从VOCs种类分析，不同行业中苯类，脂类与烷烃，酮类相对较多，其他几种成分均含量较少；溶剂使用是VOCs排放环节中的主要环节，排放贡献率达到37%；在调研609家企业中共有109家企业有VOCs控制设施，其中吸附法占比最大，占69%. |
| 英文摘要 |
| This study established a VOC emissions inventory for Qinhuangdao City using the data on the product yield, raw material use, the concentration of VOCs, the discharge flow, and activities of 609 enterprises. The amount of annual VOC emissions obtained from direct measurements and emission factor methods was 8420.07 t; 48.9% of which was from the economechnological development district, which is the major industrial source of VOCs in the region. Benzene, lipids, alkanes, and ketones were the main industrial VOC components. For important VOC-emitting industries, processing of petroleum, coking, processing of nuclear fuel contributed 30.35% of total VOCs emissions in Qinhuangdao, and manufacture of chemical raw materials, chemical products contributed 14.42%. Solvent use was the most important emission link, which accounted for 37% of total industrial VOCs emissions. About 109 of 609 investigated plants have VOC treatment facilities, 69% of which are based on adsorption technology. |
