Abstract：Bench-scale tests were conducted to study the efficiency and mechanisms of the degradation of Dissolved Organic Nitrogen (DON) by solar/TiO2 photo-catalytic. The variations of soluble protein, polysaccharide and UV254 were also investigated to estimate the degradation efficiency. The elimination rate of DON was 29% after 7hours’ treatment. The concentration of NH4+ and NO3- was increased significantly while TN had no noticeable change. Additionally, the elimination rates of soluble protein and polysaccharide were 48.6% and 54.5%, respectively. Other water quality indexes like UV254, turbidity and DOC were also decreased moderately in this process.
