Domestic sewage treatment device for environmental protection engineering

Abstract

The invention discloses a domestic sewage treatment device for environmental protection engineering, and relates to the technical field of sewage treatment. The device comprises a treatment box, the upper surface of the treatment box is fixedly communicated with a liquid inlet hopper, limiting rods are fixedly connected to the inner walls of the two sides of the treatment box, a filter screen plate is arranged between the inner walls of the two sides of the treatment box, the limiting rods penetrate through the two side walls of the treatment box and are slidably connected with the treatment box, and the outer surfaces of the limiting rods are sleeved with reset springs; a plurality of uniformly distributed clamping blocks are fixedly connected to the lower surface of the filter screen plate, a rotating motor is fixedly mounted on the rear end face of the treatment box, a mounting rod is fixedly connected to the output end of the rotating motor through a coupler, a roller is fixedly mounted on the outer surface of the mounting rod, and a plurality of uniformly distributed tooth blocks are fixedly connected to the outer surface of the roller, and the clamping blocks are engaged with the tooth blocks. The problems that according to an existing sewage treatment device, a filter screen plate is difficult to shake, and impurities left on the filter screen plate are difficult to treat are solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a domestic sewage treatment device for environmental protection engineering. 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.). The organic matter in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens multiply by using the organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated be...
