Principle of ozone treatment of sewage

Principle of ozone treatment of sewage

The principle of ozone treatment of sewage is mainly based on the strong oxidation of ozone. Ozone (O₃) is a substance with high oxidation potential, which can quickly spread into the interior of microbial cells, destroying their cell walls and enzymes in the cell, leading to cell lysis and death. Ozone disinfection is very rapid and thorough, its bactericidal power is 600 to 3000 times that of conventional chlorine dioxide. Ozone kills viruses, bacteria, spores and other microorganisms by oxidizing organic matter in microbial cells or destroying organic chain structures. Its sterilization rate is over 99.9%.

The specific application and effect of ozone treatment of sewage

Disinfection and sterilization: ozone can quickly kill microorganisms such as bacteria, viruses and spores in water, and the disinfection effect is remarkable.

Removal of pollutants: ozone can oxidize and decompose phenol, cyanide, iron, manganese and other pollutants in water, and remove the color, odor and odor in water.

Decomposition of organic matter: Ozone can decompose organic matter that is difficult to destroy by ordinary oxidants, and convert it into harmless substances.

Scientists have developed an ozone decomposition catalyst, a catalyst capable of breaking down ozone with high efficiency.

The application of ozone decomposition catalyst has great potential in ozone water treatment and ultraviolet ozone disinfection industry. They can not only improve the efficiency of water treatment and air purification, but also reduce the potential harm of ozone residues to the human body and the environment. As scientists continue to study ozone decomposition catalysts, it is believed that this technology will be more widely used in the future, and create a cleaner and healthier living environment for us.
