본 연구에서는 열처리 공정에서 발생하는 폐기물 중 무기물질류 15 종과, 유기물질류 24 종(PCDD/PCDFs, PAHs)에 대한 배출 특성을 파악하고자 수행하였다. 납 열적 야금에서 발생하는 폐기물(EWC 10 04)에서 규제 무기금속물질류 중 Pb은 가장 높은 농도를 보였다. 이는 EWC 10 04에서 분진으로 인한 결과로 판단된다. 아연 열적 야금에서 발생하는 폐기물(EWC 10 05)에서 규제 무기금속물질류 중 Zn이 높은 농도로 나타나 EWC 10 05에서 분진으로 인한 결과로 판단되며, 또한 구리 열적 야금에서 발생하는 폐기물(EWC 10 06)에서 Cu가 65,177 mg/kg으로 규제기준 (100 mg/kg)보다 651 배 높게나타난 것은 EWC 10 06에서 분진으로 인한 결과로 판단된다. 분진은 다이옥신 0.0005~11.748 ng-TEQ/g으로 검출되었고, 소각재는 0.0027 ng-TEQ/g로 나타났다. 다이옥신의 규제기준을 초과하는 시료는 없는것으로 조사되었다. PAHs의 함량은 Naphthalene는 ND~118.9 mg/kg, Phenanthrene는 ND~9.6 mg/kg, Benzo[b]fluoranthene은 ND~48.4 mg/kg, Benzo[a]pyrene는ND~62.6 mg/kg, Fluoranthene는 ND~10.7mg/kg, Benzo[a]anthracene는 ND~11.5 mg/kg의 범위로 나타났다.
In this study, heavy metals, PCDD/PCDFs, PAHs in wastes generated from thermal processes wereanalyzed. Waste from lead thermal metalurgy (EWC 10 04) inorganic metal substances in the regulation weredetected in the highest concentrations of Pb. EWC 10 04 seems to be a result of the dust. Waste from zincthermal metalurgy (EWC 10 05) inorganic metal substances in the regulation were detected in high concentrationof Zn. EWC 10 05 seems to be a result of the dust. Waste from copper thermal metalurgy (EWC 10 06)Cu in the 651,77 mg/kg to 651 times higher than regulation standard appeared in the copper thermal metallurgyprocess seems to be a result of dust. The concentrations of PCDD/PCDFs ranged from 0.0005~11.748 ng-TEQ/g in dust, 0.0027 ng-TEQ/g in fly ash. PCDD/PCDFs content was not detected in excessive value in regulationstandard. PAHs concentration was in the range of ND~118.9 mg/kg in Naphthalene, ND~9.6 mg/kg inPhenanthrene, ND~48.4 mg/kg in Benzo[b]fluoranthene, ND~62.6 mg/kg in Benzo[a]pyrene, ND~10.7 mg/kgin Fluoranthene, ND~11.5 mg/kg in Benzo[a]anthracene.
