Abstract

粗大ごみの焼却によるPCDD/Fs発生ポテンシャルを評価するために, 小型バッチ式焼却炉で冷蔵庫, 洗濯機, ベッド・マットレス・ソファ類およびテレビの焼却実験を行った. その結果, すすおよび焼却灰ともに高濃度のPCDD/Fsが検出され, 冷蔵庫, 洗濯機, ベッド・マットレス・ソファ類およびテレビのそれぞれについて, すすでは91, 73, 52, 12ng-TEQ/g, 焼却灰では68, 9, 14, 8ng-TEQ/gとなった. 焼却灰の量と濃度からPCDD/Fsの発生原単位を求めたところ, それぞれの品目で3.9, 0.27, 0.90, 0.14μg-TEQ/kg-焼却物となった.

In order to assess PCDD/Fs emission potentials of incinerated bulky wastes, combustion experiments were carried out with refrigerators, washing machines, bed mattresses/sofas, and TVs in a small-scale batch-type combustor. High concentrations of PCDD/Fs were detected in both soot and bottom ash samples. Soot samples from refrigerators, washing machines, bed mattresses/sofas, and TVs produced PCDD/Fs concentrations of 91, 73, 52, and 12ng-TEQ/g, respectively; while 68, 9, 14, and 8ng-TEQ/g, respectively were detected in bottom ash. PCDD/Fs emission factors calculated from the amount and concentrations of bottom ash were 3.9, 0.27, 0.90, and 0.14μg-TEQ/kg of the four items, respectively.
