Purification device for domestic sewage treatment

Abstract

A disclosed purification device for domestic sewage treatment comprises a box body, a built-in pull rod is arranged on one side of the box body in a penetrating mode, a push plate is fixedly connectedto the other side of the built-in pull rod, a sealing ring is arranged on the outer side of the push plate, a blocking plate is arranged in the middle of the built-in pull rod, and a first filter screen is arranged in the blocking plate; and a fixed plate is fixedly connected to the middle of the upper portion of the first filter screen, and the built-in pull rod penetrates through the fixed plate. Through the arrangment of the build-in pull rod, the push plate can be moved by pulling the built-in pull rod; through a second filter screen arranged in the push plate, precipitated impurities canbe pushed; through an arranged electric push rod, a movable plate can be opened, and one side of the movable plate is inclined, so that an opening is formed in the upper portion of a first discharging opening, impurities are discharged; and through an arranged first water outlet valve, water flow can be pumped into a reaction bin to be precipitated and then discharged from a second water outlet valve.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a purification device for domestic sewage treatment. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. 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 intestinal infectious viruses, etc.). Stable, easy to rot and produce stench. Bacteria and pathogens multiply by 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. The existing sewage treatment is mainly processed by filtering impu...

Problems solved by technology

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 intestinal infectious viruses, etc.). Stable, easy to rot and produce stench. Bacteria and pathogens multiply by 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. The existing sewage treatment is mainly processed by filtering impurities. , but direct filtration is likely to cause problems such as clogging the mesh, the filtration efficiency is not high, and it is difficult to sort and discharge the large-particle waste and sediment and other small particles that can be recycled in the water
