Description

Technical Field

[0001] The utility model relates to the technical field of CASS pool scum cleaning, in particular to an automatic CASS pool scum cleaning device. Background Art

[0002] The CASS tank, i.e., the circulating activated sludge method, has a working principle that can be divided into four stages: aeration, sedimentation, decanting, and idleness. However, during the sewage treatment process, scum is often generated. In order to prevent the scum from affecting the aeration stage, a cleaning device is usually used in the prior art to remove the scum in the pool water. For example, the patent with publication number CN218491531U discloses a scum cleaning and removal device for a sewage treatment tank. The floating scum is driven by the water flow and enters the inner cavity of the hollow cylinder through the opening under the guidance of the guide plate. The sewage continues to flow away through the filter holes at the bottom of the hollow cylinder, while the scum remains in the inner cavity of the hollow cylinder to collect and remove the scum.

[0003] However, the hollow cylinder is transversely fixed to the top of the sewage pool by a bracket. Therefore, for a CASS pool with a large sewage treatment capacity and a certain floor area, the hollow cylinder used is relatively long, which makes it inconvenient to install and fix, and even more inconvenient to disassemble and replace.

[0004] Based on the above description, there is an urgent need for a CASS pool scum automatic cleaning device that is widely applicable and stable. Utility Model Content
