Description

Technical Field

[0002] Sewage treatment is the process of purifying sewage to meet specific discharge standards or water quality requirements for reuse. A photocatalyst is a substance that does not change itself under the irradiation of light, but can promote chemical reactions. Titanium dioxide is a broad-spectrum photocatalyst with a wide range of sources and high chemical and mechanical stability. The titanium dioxide photocatalytic reaction of domestic sewage under light conditions has the characteristics of rapid sterilization, strong sterilization ability, and can mineralize organic pollutants at the same time without causing secondary pollution.
