Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a dirt removing device for sewage treatment. Background Art

[0002] Sewage treatment is a process of purifying sewage by separating pollutants contained in sewage or converting them into harmless substances by various methods. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily life of ordinary people. When treating sewage, since sewage is in contact with the inner wall of the sewage pool for a long time, dirt is likely to remain on the inner wall of the sewage pool for a long time, and it needs to be cleaned; the existing dirt removal device for sewage treatment has certain disadvantages when used. When cleaning the dirt, it is necessary to manually scrape the dirt on the inner wall of the sewage pool, rinse it with water and then discharge it. The operation is cumbersome, and there are a lot of impurities remaining in the wastewater used to clean the sewage pool. Direct discharge causes a waste of water resources. For this reason, we propose a dirt removal device for sewage treatment. Utility Model Content
