摘    要:选取了浙江省内4家典型汽车整车制造企业进行调研,并对其中的两家企业开展了实地监测,通过分析生产工艺及其所使用的主要原辅材料,确定了该行业挥发性有机物(VOCs)的主要产生和排放环节,计算了浙江省汽车整车制造行业的挥发性有机物产生和排放系数,估算了2017年全省汽车整车制造行业的VOCs产生和排放量.结果表明,浙江省汽车整车制造业的VOCs主要产生及排放环节为涂装工序;现阶段浙江省内仅有部分汽车整车制造企业对喷漆废气进行了高效处理;除涂料外,溶剂型清洗剂也是该行业VOCs的主要来源之一.计算得出的浙江省汽车整车制造业的VOCs产生系数为0.20 t·t~(-1)、 3.92 kg·辆~(-1)和29.36 g·m~(-2),排放系数为0.13 t·t~(-1)、 2.63 kg·辆~(-1)和19.72 g·m~(-2);2017年全省汽车整车制造行业的VOCs产生量为2 425.84 t,排放量为1 627.54 t.

关 键 词:浙江  汽车整车制造  涂装  挥发性有机物(VOCs)  产生系数  排放系数

Abstract:Four typical automobile manufacturing enterprises in Zhejiang Province were selected to determine the main production and emission links of volatile organic compounds (VOCs) in this industry by analyzing their production processes and the main raw and auxiliary materials used. Two of them were monitored on the spot, and the producing coefficients and emission coefficients of the VOCs discharged from the automobile manufacturing industry in Zhejiang Province were calculated. Then, the production and emission of VOCs in this industry in 2017 in Zhejiang Province were estimated. The results show that the main production and emission links of VOCs in the automobile manufacturing industry in Zhejiang Province are coating processes. Only a few of the automobile manufacturers in Zhejiang Province can deal with the paint exhaust gas effectively at present; in addition to coatings, solvent-based cleaning agents are also one of the main sources of VOCs in this industry. The VOC producing coefficients of the automobile manufacturing industry in Zhejiang Province are 0.20 t·t-1, 3.92 kg·vehicle-1, and 29.36 g·m-2; the emission coefficients are 0.13 t·t-1, 2.63 kg·vehicle-1, and 19.72 g·m-2. The quantity of VOCs generated by this industry in 2017 was 2425.84 t, while the quantity of emissions was 1627.54 t.
Keywords:Zhejiang Province  automobile manufacturing industry  coating  volatile organic compounds(VOCs)  producing coefficient  emission coefficient
