中文摘要:

为探究南方常见生物质燃烧产生的气态污染物的排放特征，利用炉灶对广西地区常见生物质燃烧产生的烟气进行实测，分析生物质燃烧排放污染物的排放因子、组分特征及化学反应活性。研究表明：生物质燃烧的CO、NOx、CH₄和非甲烷总烃（NMVOCs）的平均排放因子为36.42、1.73、0.89 g·kg^-1和2.39 g·kg^-1；乙醛是生物质燃烧排放的最主要的醛酮污染物，排放因子为147.09~599.10 mg·kg^-1；7种生物质的醛酮污染物的臭氧生成潜势（OFP）总量在6.73~18.58 mg·m^-3之间，其中甲醛、乙醛和丙烯醛的OFP较高；广西2010—2019年间生物质秸秆燃烧排放的CO、NOx、CH₄、NMVOCs及醛酮污染物的平均总排放量分别为252 660.14、19 060.86、23 765.92、52 795.02 t及40 410.62 t，水稻、玉米和甘蔗秸秆是广西生物质燃烧释放大气污染物的主要贡献源。

英文摘要:

We explored the emission characteristics of gaseous pollutants produced from common biomass combustion in south China. The flue gas produced by common biomass combustion in Guangxi was measured using a stove, and the emission factors, component characteristics, and chemical reactivity of pollutants emitted by biomass combustion were analyzed. The results showed that the average emission factors of CO, NOx, CH₄, and non-methane volatile organic compounds（NMVOCs）from biomass combustion were 36.42, 1.73, 0.89 g·kg^-1, and 2.39 g·kg^-1, respectively. Acetaldehyde was the most important pollutant among the aldehydes and ketones from biomass combustion, with emission factors ranging from 147.09 mg·kg^-1 to 599.10 mg·kg^-1. The total ozone formation potential（OFP）of aldehydes and ketones of seven types of biomass ranged from 6.73 mg·m^-3 to 18.58 mg·m^-3, among which formaldehyde, acetaldehyde, and acrolein had high OFPs. The average total emissions of CO, NOx, CH₄, NMVOCs, and aldehydes and ketones from biomass straw burning in Guangxi from 2010 to 2019 were as follows：252 660.14, 19 060.86, 23 765.92, 52 795.02 t and 40 410.62 t, respectively. Rice, maize, and sugarcane straw were the main sources contributing to air pollutants released by biomass burning in Guangxi.
