[0002] Domestic sewage is wastewater discharged from residents' daily lives, mainly from residential buildings and public buildings. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and enteric infectious viruses, etc.). The organic matter in domestic sewage is extremely unstable and easily decomposes to produce a foul odor. Bacteria and pathogens multiply in large numbers using organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] In the prior art, during the pre-treatment of domestic sewage, although the sewage is filtered and treated using a filter net, in actual operation, it is impossible to effectively treat the aggregated floats floating on the horizontal plane. As a result, during a long period of treatment, the aggregated floats will form a sticky state on the filter net, affecting the filtration load of the filter net and reducing the service life of the filter net. Therefore, a new type of domestic sewage pre-treatment equipment is proposed. Utility Model Content
