標題: | 垃圾與焚化灰渣掩埋技術整合型研究(II)─子計畫二:灰渣掩埋利用技術與滲出水之污染控制 | 作者: | 楊萬發 | 關鍵字: | 飛灰;灰渣;垃圾滲出水;共同分層掩埋;重金屬;Fly Ashes;Bottom Ashes;Leachate;Heavy Metals | 公開日期: | 31-七月-2000 | 出版社: | 臺北市:國立臺灣大學環境工程學研究所 | 摘要: | 焚化法將成為台灣地區未來處理垃圾 問題的主要方法,面對將完工的多座焚化 廠,一旦運作,其每日將產生數以千噸的 焚化灰渣亟待處理。本計畫的研究主要是 以都市垃圾與焚化灰渣共同掩埋,進行管 柱淋滲實驗。實驗中所需之都市垃圾、焚 化底灰與靜電集塵飛灰和都市垃圾皆採自 於台北市木柵垃圾焚化廠。實驗中以不同 比例之飛灰和底灰,與都市垃圾共同掩埋 管柱中模擬實際掩埋場掩埋情形,藉由分 析滲出水水質來探討焚化灰渣在陸域掩埋 的情形。另以已知濃度的 滲出水安排返 送回共同掩埋層,觀察灰渣對垃圾滲出水 中有機物的吸附狀況。 Incineration will become the major way to dispose of waste .We have many incinerators which will be finished , when it works , there are thousands of ashes need to deal with everyday . Municipal solid waste(MSW) and ashes were co-landfilled in this study , and used tubes to gain the leachate . Incinerator fly ashes of EP , bottom ashes and solid waste were from Mu-Cha plant. In our plan, fly ashes, bottom ashes and MSW were co-landfilled in different ratio ; and conferred the situation about ashes which were landfilled by analysised the leachate. Besides , we sent leachate back to layer in order to observe the adsorbability of ashes. In analyzing the leachate , we observed that pH value in each tube were similar , between 6~8,and tube A had the highest COD value . Maybe there still were some organizes in fly ashes making this result. Moreover , we sent leachate back to tube B , but we found that it didn’t work in this way. Maybe the adsorbability of ashes were saturated. In analyzing negative ions , we found that Cl-> SO4 2-> NO3 -, and Cl- had the highest concentration , even up to one hundred thousand , but they all decreased gradually .Zn had the highest concentration in all heavy metals,Cu was the next , then were Cr ,Cd , Pb , and they decreased gradually, too. But in a long-time observation , we found that Cu , Pb were redissolved , maybe it’s deadsorbtion of ashes adsorbed ions. |
