Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment equipment, in particular to a domestic sewage treatment container based on ultraviolet disinfection. Background Art

[0002] Domestic sewage treatment refers to the treatment of wastewater generated by human life to reduce environmental pollution and protect human health. Domestic sewage primarily includes wastewater generated by homes, schools, hospitals, restaurants, and other places. It contains large amounts of organic matter, suspended solids, nutrients, and microorganisms. If this wastewater is discharged directly into natural water bodies without treatment, it will have a serious impact on the aquatic environment and ecosystem.

[0003] Modern sewage treatment technology can be divided into primary, secondary and tertiary treatment processes. Primary sewage treatment uses physical methods such as screening and sedimentation to remove insoluble suspended solids and floating materials in sewage. Secondary sewage treatment mainly uses biological treatment methods, that is, the process of material conversion through the metabolism of microorganisms, oxidizing and degrading various complex organic substances in sewage into simple substances. Biological treatment has certain requirements for sewage water quality, water temperature, dissolved oxygen content in water, pH value, etc. Tertiary sewage treatment is based on primary and secondary treatment, and uses physical and chemical methods such as coagulation, filtration, ion exchange, and reverse osmosis to remove insoluble organic matter, phosphorus, nitrogen and other nutrients in sewage.

[0004] Currently, the existing integrated sewage treatment equipment combines multiple treatment processes to treat sewage in order to achieve the required water quality. However, since untreated domestic sewage contains many polluting suspended solids, it is easy to clog the filter during the primary treatment, affecting the implementation of subsequent treatment processes. Moreover, the domestic sewage after simple treatment cannot meet the use requirements with higher water quality requirements. Utility Model Content
