| titleOfInvention | Activated sludge wastewater and sewage treatment using titanium dioxide photocatalyst |
| abstract | (57) [Summary] (Modified) [Problem] Oxidative decomposition of organic substances and persistent harmful chemicals from the activated sludge tank and oxidative decomposition of microorganisms in the activated sludge tank in the sewage and wastewater treatment plant, and then again in the activated sludge tank To reduce the amount of dewatered sludge as feed for aerobic microorganisms. SOLUTION: Liquefied titanium dioxide is converted into transparent glass. Attached to plastics, ceramics, and soft films that sufficiently respond to the movement of water, manufacture devices that fully utilize the photocatalytic ability of titanium dioxide, and install them in appropriate locations in activated sludge wastewater or sewage treatment plants to achieve photocatalytic effects. In other words, when light is applied to titanium dioxide, it generates a much stronger oxidizing power than ozone and chlorine, oxidizes and decomposes substances that come in contact, and decomposes microorganisms as well as organic substances and persistent harmful chemical substances. It becomes feed for the aerobic microorganisms in the activated sludge tank, and the excess sludge is completely decomposed, kept at the water quality standard value, and discharged into the river as final treated water. |
