Sludge separation device with deodorization function for domestic sewage treatment and method thereof

Abstract

The invention discloses a sludge separation device with a deodorization function for domestic sewage treatment and a method, and belongs to the technical field of sewage treatment. In order to solve the problem that odor is difficult to remove when sewage is subjected to sludge separation, a centrifugal filter cylinder is arranged in a separation cylinder, filter holes are formed in the surface of the centrifugal filter cylinder, and a second motor works to throw sludge out of the centrifugal filter cylinder by utilizing centrifugal force, so that the sludge in the domestic sewage is separated and recycled; according to the present invention, the material scraping assembly is arranged between the separation cylinder and the centrifugal filtration cylinder so as to scrape the sludge attached to the inner wall of the separation cylinder, such that the sludge separation effect is improved, the adhesion is prevented, and the activated carbon is arranged on the inner wall of the deodorization chamber so as to achieve the effect of recycling the sludge; by arranging activated carbon, odor components in malodorous gas can be adsorbed, filtered and purified, then the sludge components in the domestic sewage are deodorized in the process, the activated carbon can be repeatedly used after being replaced, and the odor treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sludge separation device with a deodorizing function for domestic sewage treatment and a method thereof. 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. The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge. [0003] Domestic sewage has many hazards, and stench is a common pollution hazard, which also occurs in pollute...

AI Technical Summary

Problems solved by technology

[0005] 1. Domestic sewage is often accompanied by a lot of sludge. The sludge separation equipment in the existing technology is often difficult to completely separate the sludge, which will affect the subsequent treatment effect of sewage

[0006] 2. When domestic sewage is separated from sludge, it is often accompanied by stench, and the smelly temperature will affect people's spirit or body, thereby affecting the health of the staff and destroying the working environment
