Automatic dredging type urban domestic sewage treatment system

Technical Field

The invention relates to the technical field of domestic sewage treatment, in particular to an automatic dredging type urban domestic sewage treatment system.

Background

Urban domestic sewage is wastewater discharged in daily life of residents and mainly comes from residential buildings and public buildings in cities, such as houses, offices, schools, hospitals, shops, public places, industrial enterprise toilets and the like. The pollutants contained in the domestic sewage are mainly organic matters and a large number of pathogenic microorganisms. 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.

Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as building, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and the urban domestic sewage is generally treated by primary filtration to remove visible domestic garbage, food waste and the like in the sewage at first, then the water quality of the sewage is treated and is discharged after reaching the standard.

At present, when urban domestic sewage is treated, a filter screen and a filter plate are generally used for filtering to filter visible domestic garbage in the sewage, but after the urban domestic sewage is used for a period of time, the filter screen is easily blocked, an effective filtering treatment effect cannot be achieved, meanwhile, garbage adhered to the outer wall of the filter screen cannot be treated, so that the filter screen needs to be replaced manually and frequently, time and labor are wasted, and the sewage treatment efficiency is low; and the garbage blocked by the filter screen can not be effectively treated, which is not beneficial to the treatment of sewage. Therefore, an automatic dredging type municipal sewage treatment system is proposed to solve the above problems.
