摘要:基于各行业的涂料当前消费量和未来消费预测,以及各行业使用涂料的挥发性有机物(VOC)含量,建立了分省、分行业、分化学组分的排放清单模型,获得2005~2020年中国涂料应用过程的VOC排放清单.结果表明,2005年,我国涂料应用共排放VOC约1 883 kt,以苯系物、醇、酯、醚、酮5类化合物为主,平均增量反应活性指标(以O_3/VOC计)约为3.6 g/kg,其中31%的VOC为有毒物质.如不加强控制,到2020年该部门VOC排放量将激增至5 673 kt;因此,国家应及时开展其排放控制行动.排放控制情景分析表明,通过提高涂料产品品质达到发达国家上世纪末水平,且要求新建规模企业安装有机废气末端处理设施,2020年该部门VOC排放量可控制在3 519 kt;通过进一步将建筑涂料和木器涂料改进到当前欧美发达国家先进水平,且规模企业均安装有机废气末端处理设施,2020年该部门VOC排放量有可能控制在2 243 kt.2种控制情景下所排放VOC的化学毒性和大气氧化活性均得到了有效改善.
Abstract:Based on the current consumptions and forecast consumptions of paints in China, using the volatile organic compounds (VOC) contents of paints calculated as emission factors, an emission inventory model was established to calculate provincial, sector-specific, and species-specific VOC emissions during 2005-2020.The results indicated that the VOC amount emitted from paint use was 1 883 kt in 2005,of which aromatics, alcohol compounds, ester compounds, ether compounds and ketone compounds were the main species. The maximum incremental reactivity (MIR,O_3/VOC) of VOC emitted in 2005 was about 3.6 g/kg, and the toxic VOC accounted for 31% of the total in weight. The VOC emissions would increase to 5 673 kt in 2020 if there were no further control policies and actions taken. Therefore, it is essential to implement the VOC emission control from paint uses as soon as possible. Two control scenarios were developed to evaluate the potential of VOC emission reductions. In 2020,VOC emissions from paint uses might be controlled at 3 519 kt through the improvement of paints quality to the level of that in developed countries in 1990s and installation of waste gas treatment equipments in newly-built factories. VOC emissions could be further reduced to 2 243 kt if the quality of decorative paint and wood paint would be improved to the current level of that in developed countries and all factories install waste gas treatment equipments. All these control measures also helpe to reduce the toxicity and atmospheric oxidation reactivity of VOC emissions.
