摘要: 对大气可吸入颗粒物采样器进行改装，建立了垃圾焚烧炉烟气中PM10采样系统，并采集了三家垃圾发电厂焚烧炉排放烟气中的可吸入颗粒物。利用GC-MS对可吸入颗粒物中的16种多环芳烃进行定量研究，获得了多环芳烃的质量分数和浓度，并对不同环数的芳烃进行了比较，分析了不同样品中的多环芳烃的毒性参数。结果表明，颗粒物中的多环芳烃主要集中在4环、5环和6环，3环和2环所占比例较少；与燃煤电厂相比，垃圾焚烧发电厂排放的烟气中多环芳烃的浓度和毒性参数更高。Abstract: The sampler for PM10 from atmosphere was refit, with which a set of PM10 (inhaled particulate matter) sampling system applied in flue gas from waste incinerators was established. With the sampling system PM10 from 3 different incinerators was sampled respectively. 16 kinds of polycyclic aromatic hydrocarbons (PAHs) in PM10 were quantified by GC-MS. The mass fraction of PAHs in PM10 and the concentration of PAHs in flue were obtained. The PAHs with different rings were compared. And the toxic parameters of PAHs were analyzed. The result show that most of the PAHs in PM10 is of 4, 5, and 6 rings, while only little PAHs is of 3 and 2 rings. Compared with coalfired power plant, the concentration and toxic parameters of PAHs emitted from waste incinerators are higher.
