Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a domestic wastewater disinfection treatment device. Background Art

[0002] Domestic sewage is wastewater discharged from residents' daily lives. It mainly comes from residential and public buildings, such as residences, institutions, schools, hospitals, shops, public places and toilets in industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms.

[0003] In the process of domestic wastewater treatment, multiple steps are generally required to perform filtering operations. Among multiple filtering operations, it is difficult to filter viruses and bacteria in wastewater. Cities are generally equipped with large-scale sewage treatment plants, and chemical agents are generally used for sterilization and disinfection operations. However, in some specific scenarios, large-scale treatment equipment is not available, and filtering or some basic wastewater treatment equipment is generally used. Therefore, ozone sterilization and disinfection are generally used. However, in actual use, the cost of using ozone is relatively high. In addition to chemical agents and ozone, ultraviolet disinfection is also used. However, ultraviolet disinfection requires a larger ultraviolet sterilization and disinfection pool for long-term irradiation to ensure the sterilization and disinfection effect.
