红河州人为源大气污染物排放清单及特征研究

Emission inventory and characteristics of anthropogenicair pollutant sources in Honghe

通过收集红河州人为源活动水平数据,基于《城市大气污染物排放清单编制技术手册》方法,建立了2017年红河州人为源大气污染物排放清单。结果显示,2017年红河州CO、NOx、SO2、VOC S、PM 2.5、PM 10、BC、OC和NH 3的排放总量分别为414340、53148、62272、70546、29486、58539、2954、6664和97452 t。化石燃料和固定燃烧源是SO2、NO x和CO的最大排放贡献源,扬尘源、固定燃烧源、工艺过程源和生物质燃烧源是颗粒物的主要排放源,溶剂使用源是VOC S排放主要贡献源,NH 3排放主要来源于农田氮肥施用和畜禽养殖,BC主要来源于化石燃料和固定燃烧及生物质燃烧,OC主要来源于生物质燃烧。个旧、开远、蒙自、弥勒和建水是CO、NOx、SO2、VOC S、PM 2.5、PM 10、BC、OC和NH 3的主要排放城市,分别占全州排放总量的92.72%、79.22%、92.23%、63.90%、61.94%、51.96%、61.94%、61.94%和53.54%。

With collecting data and referring to the Technical Manual for Urban Air Pollutant Emission Inventory Compilation,we established the 2017 air pollutant emission inventory from huluan activty of Honghe.The results showed that the total emissions of CO,NOx,SO2,VOCs,PM 2.5,PM 10,BC,OC and NH 3 in Honghe Prefecture in 2017 were 414340,53148,62272,70546,29486,58539,2954,6664 and 97452 tons respectively.Fossil fuels and stationary combustion are the largest contributor of SO2,NOx and CO.Fugitive dust,stationary combustion,production process and biomass combustion are the main emission sources of particulate matter,and solvent usage are the main sources of VOCs emission.NH 3 emissions mainly come from the use of nitrogen fertilizer in farmland and livestock and poultry breeding.BC mainly comes from fossil fuels and stationary combustion and biomass combustion.OC mainly comes from biomass combustion.Gejiu,Kaiyuan,Mengzi,Mile and Jianshui are the main emission cities of CO,NOx,SO2,VOCs,PM 2.5,PM 10,BC,OC and NH 3,accounting for 92.72%,79.22%,92.23%,63.90%,61.94%,51.96%,61.94%,61.94%and 53.54%of the total emissions of the state respectively.
