| 摘 要： | 本研究采用静电低压撞击器(ELPI)采集垃圾焚烧厂排放颗粒物,分析颗粒物中元素和碳组分,对其中OC、EC和重金属元素在14个粒径段的粒径特征进行分析,并建立了垃圾焚烧厂源PM_1、PM_(2.5)和PM_(10)的元素和碳组分成分谱,以期为精细化来源解析提供参考.结果表明,垃圾焚烧厂排放颗粒物的主要组分有Al、Si、S、Ca、Cr、Fe、OC和EC等(质量分数≥1%),其中OC和Ca的含量较高,在PM_(2.5)中的质量分数分别为10. 15%和12. 37%;重金属含量Cr Pb Zn Mn Cu Cd Ni,其中Cr和Pb在PM_(2.5)中的质量分数分别为1. 83%和0. 74%,Cr在PM_1中的质量分数达到3. 53%; OC在2. 39～3. 99μm和6. 68～9. 91μm这2个粒径段的含量达到峰值,分别占OC总含量的15. 02%和20. 45%,但在细颗粒物中的含量高于在粗颗粒物中的含量,EC在细颗粒物中的含量远高于在粗颗粒物中的含量,在0. 382～0. 613μm粒径段占14. 8%; Cr、Mn、Ni、Cu、Zn、Cd和Pb等重金属元素主要富集于细颗粒中.
