摘要
本研究探討都市垃圾焚化爐底灰與飛灰(含微奈米)與土壤不同比例熱融後(1200與1400℃)之特性研究。底灰鹼金屬Ca, Mg, K, Na與重金屬Cd, Cr, Cu, Ni, Pb, Zn總量分別為303.5, 17.42, 153.14, 48.93, 3.81, 1.23, 0.22, ND, 51.51, 23.42 mg/g。飛灰鹼金屬Ca, Mg, K, Na與重金屬Cd, Cr, Cu, Ni, Pb, Zn總量分別為104.22, 86.86, 22.35, 25.01, 0.26, 2.15, 0.41, 0.36, 5.64, 7.20 mg/g。實驗結果得知，1200與1400℃熱融試體之抗壓強度(kg/cm2)順序皆為混合灰25%+土壤75% > 混合灰50%+土壤50% > 混合灰75%+土壤25% > 底灰100% > 底灰50%+飛灰50% > 飛灰100% (重量比)。而1400℃熱融試體之抗壓強度(kg/cm2)皆相對小於1200℃熱融試體之抗壓強度(kg/cm2)。而於同樣溫度下，微奈米灰燼各項配比試體之抗壓強度，皆大於非微奈米灰燼之各項配比試體之抗壓強度。各項試體之毒性溶出試驗(Toxicity characteristics leachate procedure, TCLP) Cd, Cr, Cu與Pb濃度，皆符合法規標準濃度1, 5, 15與5 mg/L之標準濃度。

This paper aims at investigating the characteristics of various weight ratios of municipal solid waste (MSW) incinerator bottom ash (BA) and fly ash (FA) with soil melted under 1200 and 1400oC. Ca, Mg, K, Na, Cd, Cr, Cu, Ni, Pb, Zn of BA were measured to be 303.5, 17.42, 153.14, 48.93, 3.81, 1.23, 0.22, ND, 51.51, 23.42 mg/g while those of FA were found to be 104.22, 86.86, 22.35, 25.01, 0.26, 2.15, 0.41, 0.36, 5.64, 7.20 mg/g respectively. Results also showed that compressed strength under 1200 and 1400 oC followed the order of mixed ash 25%+soil 75% > mixed ash 50%+soil 50% > mixed ash 75%+soil 25% > BA 100% > BA 50%+FA 50% > FA 100%. Compressed strengths of 1400 oC molten samples were comparatively found lower that those of 1200 oC molten ones. All samples with various ratios also showed that micro-nano scale samples had higher compressed strengths than non micro-nano scale ones. In addition, Cd, Cr, Cu and Pb of all samples released by TCLP also showed that they met the regulatory standard of 1, 5, 15 and 5 mg/L. These experimental results implied that BA and FA had the potential for civil aggregate utilization and lower temperature and micro-nano scale conditions favored the compressed strength.
