Emission Characteristics and Priority Classification Control of Anthropogenic VOCs Sources in Beijing-Tianjin-Hebei Region

  • 摘要: 挥发性有机物(volatile organic compounds, VOCs)是细颗粒物(PM2.5)与臭氧(O3)的重要前体物,对我国城市复合污染的形成有重要影响,京津冀区域大气污染问题严峻,VOCs排放源类别复杂,且排放量基数大,亟需形成有效的VOCs管控策略. 因此选取京津冀区域人为源VOCs排放为研究对象,建立2018年分行业分物种VOCs排放清单,并基于实测与文献调研的行业VOCs成分谱数据,获取各排放源臭氧生成潜势(ozone formation potential, OFP)与二次有机气溶胶生成潜势(secondary organic aerosol formation potential, SOAP),同时构建VOCs排放源优先控制分级技术方法,计算各排放源分级指数,明确优先控制排放源目标. 结果表明:①京津冀区域2018年人为源VOCs排放总量为214.0×104 t,其中芳香烃、烷烃与含氧有机物为主要物种. ②小型客车、工业防护涂料、重型货车、焦化行业是OFP与SOAP的最主要来源. ③工业防护涂料、小型客车、重型货车、焦化行业、钢铁行业、供暖燃烧、生物质燃烧源的分级指数均较高. 研究显示,基于行业VOCs排放量、OFP和SOAP的单一因素制定管控策略存在一定的局限性,为了实现PM2.5与O3的科学协同防控,建议加强基于综合因素研究得到的分级指数较高排放源的控制.
