| 中文摘要 |
| 汽车维修行业是北京市重要的生活源挥发性有机物（VOCs）排放源.目前,针对汽车维修行业VOCs排放的研究仅聚焦喷烤漆房的有组织排放,尚无对于钣金,机修和美容环节VOCs的排放特征研究,没有全生产流程的汽车维修行业VOCs清单.本研究在北京市选取2个辖区街道全部137家汽车维修业进行实地调查.通过活动水平调研,原辅料VOCs含量检测,治理设施治理效率检测,获得钣金喷漆环节与机修环节VOCs排放因子（E钣喷=254 g·辆-1,E机修=237 g·辆-1）.通过聚类分析,得到5类不同汽车维修企业并分别计算了其单店年均VOCs排放总量（Ⅰ类为0.07 t,Ⅱ类为0.36 t,Ⅲ类为1.59 t,Ⅳ类为0.83 t,Ⅴ类为2.54 t）.结果发现,钣金喷漆仍是VOCs排放的重要环节,鉴于较高的机修车辆数,机修环节VOCs排放总量不容小觑；4S店（Ⅲ类至Ⅴ类）和加盟店（Ⅱ类）具有更高的活动水平. |
| 英文摘要 |
| The vehicle repair industry is an important source of volatile organic compound （VOCs） emissions in Beijing. Currently, research on VOCs emissions from the auto repair industry focuses only on organized emissions from spray painting booths and research has not been carried out on the emission characteristics of VOCs in sheet metal, machine repair, and beauty processes. A comprehensive list of VOCs emissions from the entire production process of the auto repair industry lacks. This study selected all 137 auto repair businesses in two districts of Beijing for field investigation. Through activity level research, VOCs content testing of raw and auxiliary materials, and testing of the efficiency of governance facilities, we obtained VOCs emission factors for sheet metal spray painting and machine repair processes （EPainting=254 g·car-1, EMaintain=237 g·car-1）. Through cluster analysis, we obtained five different types of auto repair businesses and calculated their annual VOCs emissions per store （cluster Ⅰ 0.07 t, cluster Ⅱ 0.36 t, cluster Ⅲ 1.59 t, cluster Ⅳ 0.83 t, and cluster Ⅴ 2.54 t）. The study revealed that sheet metal spray painting remains an important source of VOCs emissions. Given the high number of machine repair vehicles, the total VOCs emissions from the machine repair process cannot be ignored. The 4S stores （cluster Ⅲ to cluster Ⅴ） and franchise stores （cluster Ⅱ） had higher activity levels. |
