The above treatment was evaluated by virtue of the literature review, principle of remediation, removal efficiency, real remediation cases and cost in order to clearly understand its merit, constraints, the best way to implement and to provide the domestic practitioners for assessing the remediation technique considering the economic benefit and the remediation schedule. The integration of the in-situ chemical oxidation (ISCO), the air sparging (AS) and soil vapor extraction (SVE) is an innovative technology. However, as the domestic remediation cases are concerned, the local contractors use gravitational injection to inject chemical oxidants in order to save cost. The present research found that the difference of the remediation schedule between the cases treated by the integrated AS and SVE and those treated by the integrated Fenton’s agent of the ISCO, AS and SVE is not significant in the remediation site with hydraulic conductivity ≧ 10-4cm/s and benzene concentration < 750ppb in groundwater. Regarding the remediation cases of the early discovered gasoline leakage from the gas station, in order to shorten the remediation period, the polluted soil was first completely removed and exchanged, then the polluted groundwater was treated by the integrated ISCO, AS, and SVE technology. The above remediation method is deemed favorable as the economic benefit and remediation schedule are concerned. However, it should be cautious about whether or not treating the groundwater by the chemical oxidation when considering the water quality protection of the water resource and environment sensitive region. 林鎮洋 2006 學位論文 ; thesis 98 zh-TW |
