NPVOC removal and disinfection of microorganism using Titanium photocatalysis system in wastewater treament plant

摘要

PURPOSE: Disclosed is a photocatalytic system using sunlight or ultraviolet rays(UV) for disinfecting wastewater and removing non-biodegradable organics from wastewater. The photocatalytic system is adopted at a biological process for replacing conventional chlorine disinfection having several defects. Final treated water is used as tap water for miscellaneous purpose. CONSTITUTION: The photocatalytic system is installed in a final settling basin. When sunlight or UV is irradiated at wastewater, oxygen and OH- radicals are generated. Thereby, wastewater is disinfected, and non-biological organics are removed by oxidation ability of the radicals. The system is cylinder-shaped and transparent for irradiation of sunlight. And photocatalyst made of titanium is packaged in the system.
