Crank connecting rod type domestic wastewater treatment device with double decontamination effects

Abstract

The invention discloses a crank connecting rod type domestic wastewater treatment device with double decontamination effects. The crank connecting rod type domestic wastewater treatment device comprises a bottom plate, a decontamination box is mounted on the left side at the upper end of the bottom plate, filter screens are arranged inside the decontamination box, scraping plates are arranged between the filter screens, an aeration tank is mounted on the right side at the upper end of the bottom plate, a drive shaft is mounted inside the aeration tank, the upper end of the drive shaft penetrates through the aeration tank and is connected with a rotating cam, air entraining cylinders are mounted on the two sides at the upper end of the aeration tank, a rotating gear is connected with the top end of the drive shaft, a supporting frame is mounted at the upper ends of the air entraining cylinders, a supporting plate is mounted at the upper end of the supporting frame, a driving shaft is mounted at the upper end of the air entraining cylinder on the right side, a crank is mounted in the middle at the upper end of the driving shaft, a sliding sleeve is arranged in the middle of the crank, a connecting rod is hinged to the left end of the sliding sleeve, a moving rod is hinged to the left end of the connecting rod, and a rack is connected with the left end of the moving rod. The crankconnecting rod type domestic wastewater treatment device disclosed by the invention has the benefits that the primary treatment of domestic sewage is realized; meanwhile, when stirring blades rotate,aeration can also be performed into the aeration box through aeration nozzles, so that the treatment effect on the domestic sewage is enhanced.

Description

technical field [0001] The invention relates to the technical field of waste water treatment equipment, in particular to a crank connecting rod type domestic waste water treatment device with double decontamination effects. Background technique [0002] Domestic wastewater is the wastewater discharged from the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and toilets of industrial enterprises. The pollutants contained in domestic wastewater 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 present in the domestic wastewater is extremely unstable and easily corroded to produce foul odors. Bacteria and pathogens multiply with organic matter in domestic wastewater as nutrients, which can lead to the...

Problems solved by technology

[0004] However, the traditional domestic sewage aeration treatment is often ineffective. Usually, the agitator is used to stir in the aeration tank to increase the contact area between the wastewater and the outside air, so as to achieve the purpose of aeration, and then this aeration The method is often single, and the aeration efficiency is low, so that the wastewater treatment effect is not good, it is difficult to meet people's growing sewage treatment needs, and the practicability is not strong
