中文摘要 | 利用現地共代謝氣提法提供微生物生長所需基質,已被廣泛應用於生物復育場址。該整治方式之優點,即為改善微生物堵塞之工程瓶頸。但對於操作條件的工程設計,尚缺乏參考指標。本文利用氣體通道之概念模式,建構共代謝氣提法溶解效率之數學模式。該數學模式利用基質物化性質、含水層參數、及現地操作條件,預測氣態基質在含水層之暫態溶解效率。本文並建立砂箱甲苯蒸氣之溶解試驗,藉由該試驗驗證溶解效率模式。經試驗證實,本文所建立之溶解效率模式可提供共代謝氣提法之工程設計指標。 |
英文摘要 | Delivering electron acceptors, electron donors, and nutrients in gas state has been practiced for in-situ bioremediation. A mathematical model based on air channel concept was developed in this paper to assess the dissolution transient behavior of gaseous substrates for an in-situ sparging process using their chemical and physical properties, aquifer-media characteristics, and field operating conditions. Using toluene as an example, the model was verified with experimental data obtained at field sparging rates ranging from 40 L air/min to 80 L air/min. The verified model is a useful means of predicting the dissolution behavior of gaseous substrates during sparging in an unconfined aquifer. |
