유류오염토의 저온 열탈착을 이용한 TPH/BTEX 제거

다국어 초록 (Multilingual Abstract)

In recent years, petroleum has been discharged continuously into the environment increased in quantity. It is necessary for petroleum overflowed to soil to follow the control constantly because it is related to contaminate air, ground water and other substance as well as soil. The purpose of this study is to evalute the low temperature thermal desorption equipment in order to select optimal operating condition for the remediation of oil contaminated soil. Low temperature thermal desorption can be used efficiently as a remediation method for the treatment of contaminated soils. Namely that systems were used to treat soil contaminated with total petroleum hydrocarbons and polycyclic aromatic hydrocarbons, polychlorinated biphenyls with varying degrees of success. The used soil for the test is the soil of the area where it is widely contaminated with the petroleum. TPH in the soil indicates the value of 4080mg/kg and the initial concentration of BTEX reach 1619.2mg/kg under moisture content of 11.62%. In the Foundation test, the soil characterized as sand is distributed uniformly. And the suitable size of soil for the equipment is 2mm. For the pilot scale experiment, it is examined the contaminant removal efficiency of contaminated soils and found the optimal range of operating condition in the process. It can be derived from the series of experiments that the low temperature thermal desorption method for the remedition of contaminated soils can be applied effectively and efficiently and the optimal operating condition can be achieved from the control of retention time and temperature.
