本研究係針對廢油泥與廢塑膠進行批次式焚化爐混燒實驗,對煙道氣中微
量有害有機物-多環芳香烴化合物(PAHs)進行監測,藉由改變廢油泥與
廢塑膠之混合比例,以探討排放廢氣中PAHs之特徵。實驗中對於混燒比例
與PAHs排放濃度之關係及PAHs輸出/輸入之特性,為本研究之重點。本研
究之結果顯示,不同混燒比例排放PAHs於氣相、粒狀物相之濃度及殘餘灰
燼中之含量,均隨廢油泥佔整個混燒物中之比例成正比關係,且氣相及粒
狀物相均呈現良好之一次線性關係。煙道中排放之總PAHs濃度平均為648
ug/Nm3 ,灰燼中總PAHs之平均含量為3.03ug/g,總PAHs平均排放率為175
mg/hr,平均排放係數為13.2mg/Kg-廢棄物。排放廢氣中以氣相PAHs分佈
為主,平均濃度為606ug/Nm3 ,佔 93.5%,其中以Nap 之平均濃度最高
為495ug/Nm3 ,DBA 最低為0.61ug/Nm3,而粒狀物相平均濃度為42.0ug/
Nm3,佔6.48% ,其中COR 平均濃度最高,為13.4ug/Nm3,而CHR 最低,
僅0.24ug/Nm3。灰燼中之PAHs平均含量均相當低,主要以BaA、PER及 COR
最高,分別為0.40、0.37與0.32ug/g, Flu 之平均含量最低,僅有0.04
ug/g。焚化爐煙道排氣中總PAHs平均濃度約為周邊大氣之 424倍,且氣相
及粒狀物相之分佈比例與大氣中之分佈不盡相似。各試程所排放PAHs之平
均輸出總量,以氣相佔88.1% 為主,殘餘灰燼中6.14% ,粒狀物相5.79%
最低。各試程總PAHs之輸出/輸入比值介於0.004∼0.289,顯示出大多數
之PAHs於焚化過程已被破壞去除。廢油泥以焚化法處理,再加上空氣污染
防制設備去除大部分煙道氣中之空氣污染物,則其所造成之環境污染之潛
能,應遠小於掩埋處置。

A batch-type, controlled-air incinerator was used for the
treatment of oily sludge and plastic waste mixtures. Those
concentration and composition of 21 individual PAHs(Polycyclic
Aromatic Hydrocarbon) in the rawwastes, flue gas ( gas and
Particle phases), and ash were determined. Stack flue-gas
samples were collected by a PAH stack-sampling system. Twenty
one individual PAHs were analyzed promarily by a gas
chromatography and a gas chromatography/mass spectrometer.
Total-PAH concentration in flue gas and its composition in ash
averaged 648ug/m3 and 3.03 ug/g, respectively. Phase
distribution of total-PAH in the flue gas was mainly in gas
phase (93.5%) with a mean-concentration of 606ug/m3, while the
total-PAH concentration in particle phase (averaged 42.0ug/m3)
only represented a small fraction (6%) for the total-PAH mass
collected. In the gas phase of stack flue-gas, Nap had highest
mean- concentration (495ug/m3), while DBA had lowest mean-
concentration (0.61ug/m3) among these twenty one individual
PAHs. In the particle phase, COR and CHR were found to be with
highest and lowest mean-concentration (COR:13.4ug/m3 and CHR:
0.24ug/m3), respectively. In ash, BaA had highest mean-
composition (0.40ug/g), while Flu had lowest mean-composition
(0.04 ug/g). After evalution the PAHs mass from three input
sources (diesel , ambient air, and waste mixtures) of
incinerator, the diesel was found to be with the highest
fraction (averaged 99.5) entered the incinerator. The PAH-mass
input/output ratio were between 0.004 and 0.289. This results
indicated that most of PAHs entered the incinerator had been
destroyed during the combustion process. THerefore, the oily
sludge treated by the incineration process can reduce the total-
PAH mass been discharged to the environment.
