計畫中文摘要	自「土壤及地下水汙染整治基金管理委員會」成立以來，積極推動污染源稽查管制，污染區改善整治，並建立相關之監測制度。相較於工業儲槽與管線滲漏後之調查、土壤與地下水監測、整治改善，若能更積極推動儲槽與管線之防漏與滲漏監測技術，應可將防治工作更往源頭推動，達到土壤與地下水污染預防的效果。 為了克服滲漏監測的問題，近年來提出了基於電磁波時域反射法的新滲漏監測方法，TDR技術的適用性獲得實驗室與一系列現地測試實驗之驗證。TDR滲漏監測技術的基本原理主要是利用漏水造成感應纜線對應位置電學性質的改變，造成傳輸線在漏水處因電學阻抗改變而產生反射訊號，如同沿著感應纜線的漏水雷達。目前TDR滲漏監測技術的發展目的主要在於供水管線的滲漏監測，然而，工業液體如油品等非水相液體，其介電度甚低，工業廢水的電學性質也比較複雜，因此TDR滲漏監測技術是否可適用在不同的監測環境需求，需要進一步的研究與調適。本計畫發展TDR技術在儲槽與管線滲漏監測的應用，完成評估不同感應元件(纜線)偵測的適用性與感應元件的優化，發展出適用於土壤與地下水污染防治的滲漏監測技術。
計畫英文摘要	Compared with the investigation, soil and groundwater monitoring, and improvement of industrial storage tanks and pipelines after leakage, if the leakage prevention and leakage monitoring technologies of storage tanks and pipelines can be promoted more actively, the prevention and control work should be promoted to the source. Achieve the effect of soil and groundwater pollution prevention. In order to overcome the leakage monitoring problems, a new leakage monitoring method based on electromagnetic wave time domain reflectometry has been proposed in recent years. The applicability of TDR technology has been verified by the laboratory and a series of on-site testing experiments. The basic principle of TDR leakage monitoring technology is mainly to use the leakage of water to cause the electrical properties of the corresponding position of the induction cable to change, which causes the transmission line to produce a reflected signal due to the change of electrical impedance at the water leakage, just like along the induction cable Leakage radar. At present, the development purpose of TDR leakage monitoring technology is mainly to monitor the leakage of water supply pipelines. However, industrial liquids such as oil or other nonaqueous liquids have very low dielectric properties and the electrical properties of industrial wastewater are also more complicated. Therefore, whether the TDR leakage monitoring technology can be applied to different monitoring environmental requirements requires further research and adjustment.
