issues in the current UV disinfection studies to improve the ultraviolet disinfection effect in the wastewater treatment plant and inhibit the photoreactivation of micro- organisms in water. TiO2 photocatalytic oxidation is an advanced oxidation process. Its main principle can be described as follows: Under the action of ultraviolet (UV) energy, TiO2 can stimulate the generation of hydroxyl radical......
