(57) Abstract:
(EN): According to one embodiment of the present invention, a complex electrokinetic decontamination apparatus is capable of removing radionuclide from contaminated soil with high decontamination efficiency by applying a washing decontamination method by means of electrolytes inside an electrokinetic unit and a complex electrokinetic decontamination method by means of kinetic electricity. Furthermore, the invention can reduce the production and particle size of metal oxides by adjusting the pH of a cathode chamber and an anode chamber, by a pH control unit, to an optimum value. Additionally, the level of electrolyte in the electrokinetic unit can be adjusted automatically by an electrolyte supply amount control unit(129).
(FR): Selon un mode de réalisation de la présente invention, un appareil de décontamination électrocinétique complexe est apte à retirer un radionucléide d'un sol contaminé avec une efficacité élevée de décontamination par application d'un procédé de décontamination par lavage au moyen d'électrolytes à l'intérieur d'une unité électrocinétique et un procédé de décontamination électrocinétique complexe au moyen d'électricité cinétique. En outre, l'invention peut réduire la production et la taille de particule d'oxydes métalliques par ajustement du pH d'une chambre de cathode et d'une chambre d'anode, par une unité de commande de pH, à une valeur optimale. De plus, le niveau de l'électrolyte dans l'unité électrocinétique peut être ajusté automatiquement par une unité de commande de quantité d'alimentation en électrolyte (129).
(KO): 본 발명의 일실시예에 따른 복합 동전기 제염장치는, 동전기 유닛의 내부에서 전해액에 의한 세척 제염 방식과 동전기에 의한 동전기 제염 방식을 복합적으로 적용시켜 오염토양으로부터 방사성핵종을 높은 제염효율로 제거할 수 있다. 또한, pH 조절 유닛에 의해 양극실과 음극실의 pH를 최적값으로 조절하여 금속산화물의 발생량 및 입자 크기를 감소시킬 수 있다. 또한, 전해액 공급량 조절부(129)에 의해 동전기 유닛 내의 전해액 수위가 자동적으로 조절될 수 있다.
