利用百慕達草及假儉草復育受柴油污染土壤 之植生復育 王敏昭1 張簡水紋2 許鳴翔3 摘要 總石油碳氫化合物的涵蓋範圍很廣，舉凡日常生活上所使用之汽油、柴油、燃料油、潤滑油、機油等皆是屬於總石油碳氫化合物。由於近年來開放油品進口及加油站民營化，與國內汽機車的使用大量成長，也增加了對汽油、柴油、機油、潤滑油的需求。因此，此類油品一旦發生意外或洩漏，容易危及公眾安全且造成嚴重的環境污染事件。而運用植生復育受有機污染物之土壤，為近年來廣受重視整治技術，本研究中，運用假儉草與百慕達草整治復育受有機物污染的土壤，種植於受柴油污染之紅壤、沖積土、石英砂，本試驗分為四種處理，利用盆栽試驗種植假儉草及百慕達草，分別為不種植、未添加5 %有機質、添加5 %的有機質三種不同處理的降解效果，種植假儉草及百慕達草分別種植60天，結果顯示，在未種植草種部分降解率為21-38 %，未添加5 %有機質部分處理下，種植假儉草對柴油降解率為37-58 %，種植百慕達草對柴油降解率為為36-52 %，添加5 %有機質部分情況下，假儉草對柴油降解率為55-67 %，百慕達草對柴油降解率為53-64 %，因此可說明添加於土壤中有機質對柴油降解影響有其重要性，建議以假儉草及百慕達草植生復育處理受柴油污染土壤。 關鍵字：總石油碳氫化合物、柴油、植生復育 E 2 朝陽科技大學 環境工程與管理系 副教授 3 朝陽科技大學 環境工程與管理系 研究生 Phytoremediation of Diesel Contaminated Soils by Bermudagrass and Centipedegrass Min-Chao Wang1 Shui-Wen Chang Chien2 Ming-Hsiang Hsu3 Abstract TPHs (total petroleum hydrocarbons) comprise wide range of compounds and include various compounds used in our daily life such as gasoline, diesel, fuel oils, lubricants and engine oil. Because in the past few years foreign oils and gasoline have been allowed to be imported into the country, the gas stations have become privatized and the use of automobiles and motorcycles has been on the rise, the use of gasoline, diesel, engine oil and lubricants have been increased. Therefore, when an accident or a leakage occurs, it will be likely that public safety will be jeopardized and serious pollution to the environment will be resulted. Phytoremediation is an emerging technology for the remeaiation. Using plants for the remediation of the organic pollutant soil. In recent years phytoremediation is an emerging technology of the soil remediation. this study used centipedegrass and Bermudagrass improvement of the organic matter pollution soil.In diesel contaminated pot soils, red soil, alluvial soil, and quartz sand. Each treatment had four replicates, the use pot experiment planter centipedegrass and bermudagrass. Not planted、5 % OM additions、not 5 % OM additions. The seeds of ryegrass plus alfalfa were sowd in each of and harvested
