Squeezing and separating device and method for residues in domestic sewage

Abstract

The invention discloses a squeezing and separating device and method for residues in domestic sewage. The squeezing and separating device comprises a treatment box and a plurality of supporting legs arranged at the lower end of the treatment box, wherein a feeding hopper for receiving materials is arranged on the upper left portion of the treatment box, and the lower end of the feeding hopper is connected with a disinfection assembly arranged in the treatment box and used for conducting primary disinfection treatment on sewage. The device is designed aiming at the defects of an existing device; a mixing mode of ozone and sewage is optimized to allow the sewage and ozone to be in full contact, so disinfection and sterilization effects are ensured; the sewage is allowed to flow from bottom to top, so treatment continuity is ensured; and by arranging two switchable material collecting boxes for solid-liquid separation, after switching of positions, one material collecting box continues to complete solid-liquid separation while the other material collecting box conducts unloading, and the two material collecting boxes are arranged in a staggered mode, so sewage treatment efficiency is guaranteed; and separated solid impurities can be removed in time, so the durability of the solid-liquid separation effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a device and method for pressing and separating domestic sewage residues. Background technique [0002] Domestic sewage is the wastewater discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets, etc. The pollutants contained in domestic sewage are mainly organic matter and A large number of pathogenic microorganisms, the organic matter in domestic sewage is extremely unstable, 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 carried out before discharge deal with. [0003] The existing treatment methods generally disinfect the sewage first to kill the bacteria in ...

AI Technical Summary

Problems solved by technology

[0003] The existing treatment methods generally disinfect the sewage first to kill the bacteria in it, but the existing killing methods cannot cope with the flow treatment, resulting in the inability to fully kill the sewage, and in the later stage when removing impurities The accumulation of solid impurities cannot be avoided, and it will be necessary to stop the machine to clean up the impurities at a later stage. Based on this, a device and method for squeezing and separating domestic sewage residues that help improve efficiency are now provided
