In this study, photocatalytic reaction was investigated as an advanced oxidation water treatment. Titanium dioxide was coated on a glass and used as a catalyst. Low pressure mercury lamp and black light lamp, which has similar wavelength to sun light, were used as light sources. The decomposition rate of phenol and methylene blue under various condition was determined. The role of flow condition, light intensity and specific catalyst area was quantitatively evaluated. The reaction rate followed Langmure-Hinshelwood equation, and the factors above was correlated to the parameters in the equation. Different types ofTiO2 was also tested, and the role of pH was estimated and explained from the surface charge of catalyst.GC/MS was applied to the evaluation of Natural Organic Matter (NOM). Bacterial Regrowth potential was developed as a evaluation method of NOM. Flowsitemetry was applied to counting the bacteria, and sonication was essential as pretreatment.

在本研究中，光催化反应作为一种高级氧化水处理技术进行了研究。二氧化钛被涂覆在玻璃上并用作催化剂。光源采用与太阳光波长相近的低压汞灯和黑光灯。测定了不同条件下苯酚和亚甲基蓝的分解速率。定量评价了流动条件、光照强度和催化剂比表面积对反应的影响。反应速率符合Langmure-HinShelwood方程，并将上述因素与方程中的参数进行关联。对不同类型的二氧化钛进行了测试，并从催化剂的表面电荷估算和解释了pH值的作用，并将GC/MS用于天然有机物(NOM)的评价。细菌再生长潜能是评价NOM的一种方法。细菌计数采用流动法，前处理采用超声波处理。
