    Abstract: 泡湯已成為國人主要休閒活動,為達溫泉資源保育目的,溫泉水需考慮採用循環及回收再利用,此時溫泉水需做殺菌處理。
    本研究使用紫外燈(Ultraviolet A、Ultraviolet C)、日光燈、及暗室配合添加無臭、無毒性之二氧化鈦光觸媒,比較各種光催化條件對關仔嶺泥漿溫泉水中大腸桿菌enterotoxigeic E.coli (ETEC O4)的殺菌效果。
    Taking a hot spring bath is an important leisure and entertainment in Taiwan. For resource conservation of hot spring, hot springs circulation and recycling need to be done with sterilization.
    The aim of this study is to explore the sterilization effect of both different photo-irradiation (UVA, UVC, solar irradiation, fluorescent lamp and darkroom) and dosing with odorless and non-toxic photocatalyst on E coli. (ETEC O4) in the mud hot spring of Guanziling under batch tests.
    Results show that the sterilization of E coli. (ETEC O4) in the mud hot spring of sodium bicarbonate chloride type was affected by intensity of photo-irradiation, photo-irradiation time, doage of titanium oxide. Results also reveal that the effect of photocatalysis was the best by dosing with 0.04 g/L titanium oxide, however, more than this dosage, the more dosage led to the worse sterilization effect. The dosing of titanium oxide leading to worse effects on the sterilization of ETEC O4 might be caused by some reasons of titanium oxides being not nano scale, also not calcined and modified, as well as which scattering possibly the penetrating of light.
    Keywords:photo-irradiation、titanium oxide、E coli.、photocatalysis、 mud hot spring.
