Background

Domestic sewage is wastewater discharged in daily life of residents and mainly comes from residential buildings and public buildings, such as houses, institutions, schools, hospitals, shops, public places, industrial enterprise toilets and the like. The pollutants contained in the domestic sewage are mainly organic matters (such as protein, carbohydrate, fat, urea, ammonia nitrogen and the like) and a large amount of pathogenic microorganisms (such as parasitic ova, enteroinfectious viruses and the like). Organic matters existing in domestic sewage are extremely unstable and easily decomposed to generate offensive odor. Bacteria and pathogens propagate in large quantities by taking organic matters in domestic sewage as nutrition, and can cause epidemic of infectious diseases. Therefore, domestic sewage must be treated before being discharged.

In the process of implementing the invention, the inventor finds that at least the following problems in the prior art are not solved:

(1) when the traditional domestic sewage treatment equipment collects sewage, a filter screen is required to be used for filtering garbage, the filter screen is easy to be blocked by adhesion of the garbage, and the garbage needs to be cleaned regularly by manpower, so that time and labor are wasted;

(2) organic matters are easy to adhere to the inner wall of the traditional domestic sewage treatment equipment, pathogenic microorganisms are led to propagate in a large quantity, and domestic sewage is easy to be secondarily polluted;

(3) the traditional domestic sewage treatment equipment is difficult to collect the scum with smaller upper layer of sewage;
