산 처리한 활성탄을 이용한 수중 유기물의 흡착 및 오존 분해 = Adsorption and catalytic ozonation of aquatic organic compound by acid-treated granular activated carbon

다국어 초록 (Multilingual Abstract)

Humic substances is accounted for for the largest proportion in natural organic matter(NOM) and NOM is widely distributed in varying concentration in all aquatic and soil. They can affect water quality adversely in several ways by contributing undesirable color, complexing with metal and yielding metal concentrations exceeding normal solubility. Ozonation is one of the efficient treatments for degradation of humic substances which cause some problems in water treatment. Especially, the combination of ozone and granular activated carbon was applied to degradation humic acid in aquatic system. The aim of this work to test the available of acid-treated granular activated carbon as catalyst in the ozonation of humic acid.
