中文摘要 对秦皇岛市609家工业企业VOCs的源排放和污染控制技术做了调研.结果表明，VOCs排放源排放的气体流量以石油加工、炼焦和核燃料加工业最高（>10⁵ m³·h^-1）.其余行业主要集中在10³~10⁵m³·h^-1之间.各行业源排放的VOCs浓度均小于1000 mg·m^-3，各行业的VOCs排放速率差异性较大，介于50~10000 g·h^-1之间.其中交通运输设备制造业、石油加工、炼焦和核燃料加工业、机械设备制造业、印刷和记录媒介复制业及化学原料和化学制品制造业的排放浓度和排放速率均较高.和国内之前的调查研究相比，秦皇岛市工业企业VOCs的排放水平相对较低.此次调研的609家工业企业中拥有VOCs处理设施的案例共109个.吸附技术应用的占比最大（69%）.其次为吸收技术（19%）. 英文摘要 Volatile organic compound (VOCs) emissions and control technologies of about 609 industrial enterprises in Qinhuangdao City were investigated in this study. The results showed that the exhausted emission flow rates from the industries of oil processing, coking, and nuclear fuel processing were found to be the largest sources of VOCs in Qinhuangdao City (normally above 10⁵ m·h^-1), whereas the other industrial emission flow rates were mainly within the range of 10³-10⁵ m³·h^-1. The detected VOC concentrations for all the industries were less than 1000 mg·m^-3. The VOCs emission rates were between 50-10000 g·h^-1, but demonstrated different characteristics among the various industries. It was found that the industries of transportation equipment manufacturing, petroleum processing, coking, nuclear fuel processing, machinery and equipment manufacturing, printing and reproduction of recorded media, and chemical raw material and chemical product manufacturing had much higher concentrations and emission rates than other industries did. However, the overall VOCs emission level from this city was still lower when compared to previous reports for other regions of China. The investigation of the VOCs control technology application showed that there were 109 constructed or operated VOCs treatment facilities among the 609 industrial enterprises. Activated carbon adsorption technology accounted for the largest proportion among the various techniques, with 69%, followed by absorption technology (19%).
