石家庄市PM_(2.5)工业源成分谱的建立及分析

石家庄大气污染严重,尤其是PM2.5浓度经常居高不下。为更加有效地降低PM2.5的浓度,需要对石家庄市PM2.5的来源进行精确解析。为了更加精确地进行源解析工作,需要以本地排放源的成分谱作为输入参数,目前关于石家庄市PM2.5工业源谱的研究还未见有文献报道。选取石家庄市具有代表性的若干工业,借助各种先进分析测试手段,深入细致地分析了石家庄市PM2.5的工业源谱,对于研究石家庄市PM2.5源解析具有很大的参考价值。研究发现:电力行业源谱中的Al可作为电力行业燃煤源标志性化学组分,且含量高于其他城市数据,是石家庄市电力行业源谱的显著特点;在钢铁行业源谱中,Fe和Ca的含量明显区别于电力行业源谱,可作为石家庄市钢铁行业源谱的标志性化学组分。

Establishment and analysis of PM2.5 industrial source profiles in Shijiazhuang City

The air pollution in Shijiazhuang City is serious;especially the PM2.5concentration is often high.Accurate source apportionment for PM2.5in Shijiazhuang City is needed in order to decrease the concentration of PM2.5 more effectively.CMB model which requires local source profile as an input parameter is used for the source apportionment.There is no research on the industrial source profile of PM2.5in Shijiazhuang City in current research.Several typical industries are selected in this paper for the in-depth analysis of PM2.5source profile with advanced analysis methods.It has a great reference value for the PM2.5source apportionment of pollution in Shijiazhuang City.The results show that Al could be used as the identification components for power industry in Shijiazhuang City in which the concentration is higher than in the other cities.It is a remarkable characteristic for the source profile of power industry in Shijiazhuang City.In the steel industry source profile,the concentrations of Fe and Ca are significantly different from the source profile of power industry,and they can be used as the identification components for steel industry.
