Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic reactors, in particular to an anaerobic reactor for sewage treatment. Background Art

[0002] The IC reactor is a new generation of high-efficiency anaerobic reactor, that is, an internal circulation anaerobic reactor, which consists of two upper and lower reaction chambers. Wastewater flows from bottom to top in the reactor, pollutants are adsorbed and degraded by bacteria, and purified water flows out from the upper part of the reactor. Anaerobic biological treatment forms the nutritional and environmental conditions required by anaerobic microorganisms under anaerobic conditions, and biochemically degrades organic matter through the metabolism of anaerobic bacteria and facultative bacteria. After the sewage treatment is completed, there is usually reacted sludge or organic matter attached to the inner wall and bottom wall of the reactor. When cleaning, it is usually necessary to wipe the inside with a handheld brush. If the reactor is large, it is extremely inconvenient to clean.

[0003] A search for the above-mentioned problem revealed that in the currently disclosed prior art, such as an anaerobic reactor for sewage treatment proposed in publication number CN217972756U, a number of brush plates are installed in the reactor, the brush plates are attached to the inner wall and bottom wall of the reactor, and then a motor and a rotating shaft are installed at the bottom of the reactor, which drives the reactor to rotate, so that the brush plates clean the inside of the reactor.

[0004] However, since there is a certain distance between several brush plates and the brush plates are fixed inside the reactor, when the reactor rotates, the brush plates cannot move up and down in the gaps between the brush plates. Therefore, the brush plates cannot effectively clean the inner wall of the reactor in the gaps, resulting in a poor cleaning effect on the reactor. Utility Model Content
