Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and specifically relates to a sewage treatment device containing chemical components. Background Art

[0002] Sewage treatment is a crucial environmental protection link, aiming to remove harmful substances in wastewater so that it meets the discharge standard or the standard for recycling and reuse. Sewage treatment involves multiple links and complex technologies, including initially precipitating sewage through a sedimentation device. When precipitating, a flocculant is added to the sewage. Through the action of the flocculant, originally tiny suspended particles aggregate into larger particles in the sewage, which is more conducive to their sedimentation to the bottom of the sewage by gravity.

[0003] In some existing sedimentation devices for sewage treatment, filters such as filter meshes are also provided to filter solids and liquids. After long-term use, the filter mesh will gradually become blocked, resulting in a decrease in filtration efficiency. In addition, various sundries such as sludge are easily attached to the side wall of the sewage bucket. Coupled with the fact that sundries are also easily attached to the side wall of the sewage bucket, it is inconvenient to clean. Therefore, it is necessary to develop a sewage treatment device containing chemical components. Summary of the Utility Model
