Description

1,4-dioxane was known as cancer-causing substance and one of the chemical substances which was detected at high density / high frequency in environmental water. Because 1,4-dioxane had properties of low biodegradation and high hydrophilicity, it was known that 1,4-dioxane was not removed enough by the conventional water processing technology that was mainly biodegradation and separation. In this study, the experiments on decomposition of 1,4-dioxane in leachate from landfill site by ultraviolet rays / hydrogen peroxide method (UV/H2O2) were performed and the decomposition characteristics were examined. Consequently, it was clarified that 1,4-dioxane decomposed by UV/H2O2 immediately. In addition, the model on decomposition of 1,4-dioxane and H2O2 and coexistence organic matter in UV/H2O2 reactor was constructed, it was simulated with a computer. As a result, the calculation value agreed with the experimental value very much. Namely, the prediction of the processing water and the detailed design of UV/H2O2 reactor were enabled with the model that was constructed this time.
