Abstract
Treatment performance and microbial community structure were investigated in water-soluble cutting oil treatment process using biological activated carbon. DOC removal in BAC1 column at 15oC was higher than at 25oC, but those of BAC3 column after 60days was high at 25oC. Also, quinone content of first-step reactors at 25oC and 15oC was much the same, but those of the third-step reactor at 25oC was higher than at 15oC. The dominant type of two apparatus was ubquinone (UQ)-10 followed by UQ-8. Menaquinones were detected from 25oC apparatus and effluent. This suggested that DOC removal at 25oC was advanced degradation by attached microorganisms on the activated carbon surface. The DOC removal in long-term activated carbon apparatus increased with going in BAC3 column. This indicated the influent of POC was a result of DOC removal efficiency decrease. Integrated DOC removal from start point in experiment to break point and quinone content were showed a tendency of increasing with going last-step activated carbon apparatus. Therefore, the biological activated carbon apparatus used by this study was effective treatment process in contaminated groundwater by water-soluble cutting oil.
