Title: | 垃圾與焚化灰渣掩埋技術整合型研究─子計畫一:灰渣掩埋利用技術與滲出水之污染控制(I) | Authors: | 楊萬發 | Keywords: | 飛灰;灰渣;共同掩埋;滲出水;重金屬;fly ashes;ashes;co-landfilled;leachate water;heavy metals | Issue Date: | 31-Jul-1999 | Publisher: | 臺北市:國立臺灣大學環境工程學研究所 | Abstract: | 本研究以採自北市木柵焚化廠之靜電集塵 飛灰與焚化底灰及都市垃圾共同掩埋,觀察滲 出水特性與重金屬溶出濃度變化情形,以做為 單獨處理飛灰或與底灰或垃圾掩埋處置時之參 考。實驗主要探討飛灰個別掩埋及分別與底 灰、都市垃圾共同掩埋受淋滲後,對滲出水質 及重金屬溶出變化的影響。 Incinerator fly ashes of EP (Electrostatic Precipitator) and bottom ashes from MuCha plant and municipal solid waste (MSW) were colandfilled in this study. The changes of leachate water characteristics and dissolved concentrations of heavy metals were observed to be the reference of disposal of only fly ashes or with bottom ashes and MSW. The influences of mixing type that only fly ashes, fly ashes mixing with bottom ashes and fly ashes mixing with MSW were discussed. From the results, the values of water quality analyzing and the concentrations of heavy metals were high in the initial time, and it decreased gradually. In leachate water, the concentration of Zn was the highest, Fe was the next, then was Cu, Cr, Cd and Pb. In terms of analyzing the quality of leachate water, pH between 11~12.5 was the highest when fly ashes mixed with bottom ashes. The concentration of each negative ions was highest when only fly ashes. In terms of heavy metals of leachate water, only fly ashes would make the concentration of Cd and Cr higher. From leachate water that wecould find that bottom ashes decrease the concentration of Pb and Cd in fly ashes when fly ashes mixed with bottom ashes. The changes of the concentration of leachate water was not observable when fly ashes mixed with MSW, but only the concentration of Zn has increased. |
