Description

Technical Field

[0001] The utility model relates to the technical field of sewage storage equipment, in particular to an impurity separation device for a sewage storage tank. Background Art

[0002] In the current domestic sewage treatment process, treated domestic sewage is generally discharged into the river. After being thoroughly treated, domestic sewage can also be used as irrigation water and cleaning water. The treated sewage is generally stored in a water tank, but some pollutants such as flocs or organic matter will remain in the treated sewage. The residues of these pollutants can provide nutrients for the growth of algae. Long-term storage of treated sewage will cause algae growth, affecting subsequent use. For water tanks that are used for a long time, pollutants attached to the inner wall are not easy to clean. The long-term accumulation of impurities on the inner wall of the storage tank will also cause secondary pollution to the sewage.

[0003] Therefore, an impurity separation device for a sewage storage tank is designed to solve the above problems. Utility Model Content
