| Popis: | 有害物質を含んだ固体系廃棄物を地盤工学的に有効利用する際には, 地盤環境に対する適切な影響評価を行う必要がある。本研究では有効利用を目的とした処理を行った廃棄物に対して複数の溶出試験を実施し, 地盤環境影響要因としての溶出特性, セメント固化による重金属の固定化効果, 溶出操作の相違が溶出特性に与える影響について検討し, 適切な溶出操作について議論を行った。 The leaching characteristics from the stabilized wastes are discussed from the viewpoint of landfilling and geotechnical utilization. Municipal solid waste incinerated fly ash (MSW-ash) and sewage sludge incinerated ash (SS-ash) are used for the experiment. Three different batch leaching test methods and a column leaching test are conducted. The experimental results show that the batch leaching tests could not evaluate the change in leaching characteristics due to the change in pH or the duration to contact with water. Cement stabilization would have a great effect on the immobilization of Cd and little effect on Pb. |
