[0002] Domestic sewage is the wastewater discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and the toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matters and a large number of pathogenic microorganisms. The organic matters existing in domestic sewage are extremely unstable and are prone to corruption and produce foul smell. Bacteria and pathogens multiply in large numbers by taking the organic matters in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before being discharged.

[0003] Existing domestic sewage usually carries a large number of impurities of different sizes. Sewage treatment equipment often uses a filter screen to filter solid impurities in the sewage. If impurities of different sizes are not treated, it is easy to cause equipment blockage, and at the same time affect the orderly treatment of sewage and the quality of sewage treatment. For this reason, we propose a new type of integrated domestic sewage treatment equipment. Content of the Utility Model
