Summary: | 碩士 === 國立臺灣大學 === 公共衛生研究所 === 85 === AbstractThis study evaluates the applicability of advanced
oxidation method (UV/H2O2 and UV/TiO2) to control the natural
organic matter (NOM) in drinking water. Factors considered
includes the concentrations of!NOM, presence of alkalinity and
dissolved oxygen in water. Different kinds of glass media
(quartz and pyrex glass) were used to control the penetration of
the UV lights with different wavelength.The results indicated
that the addition of 0.6% H2O2 give the best results to reduce
the NOM concentration in water. Addition of TiO2 will also
helpful in reducing the NOM concentration. The presence of
alkalinity may interfere the penetration of the UV light, hence
affect the effect of the UV oxidation process. Quartz filter is
the best media in this study for the control of the NOM, use of
the pyrex glass or other glass as the filter may stop the
penetration of the low wavelength UV light and so reduce its
oxidation ability for NOM.
