Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a self-priming collecting and filtering device for scum garbage on the surface of a secondary sedimentation tank. Background Art

[0002] Sedimentation tanks are a common type of wastewater treatment equipment. During the sedimentation process, due to the high volume of influent waste and the inability of fine screens to retain smaller debris, waste flows with the wastewater into oxidation ditches, distribution wells, and secondary sedimentation tanks. Because the secondary sedimentation tanks are equipped with stainless steel scum baffles, waste and scum float on the tank surface and accumulate, preventing them from flowing out. Sludge scrapers alone are unable to remove large amounts of scum, resulting in large areas of floating scum on the secondary sedimentation tank surface, poor visualization, and detrimental water quality. In light of this, we propose a self-priming scum and garbage collection and filtration device for the secondary sedimentation tank surface. Utility Model Content
