Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] The prior art patent announcement number CN220443333U is a solid-liquid separation device for domestic sewage treatment. The above patent sets a liquid inlet component and a vibration component, which can drive the filter plate inside the expansion shell to vibrate up and down through the vibration component. During the vibration process, the domestic water can flow faster and foreign objects can be prevented from getting stuck on the filter plate and affecting the water inlet; the cover is convenient for disassembly to clean the filter plate, but there are still the following deficiencies in actual use: from a practical point of view, although the prior art makes the domestic water flow faster through vibration and prevents foreign objects from getting stuck on the filter plate, the solid impurities separated by the filter plate are still accumulated on the filter plate. With the increase of solid impurities, the filter plate will still be blocked. Even if vibration is performed, the speed of water flowing through the filter plate will gradually decrease, making the solid-liquid separation effect worse. At the same time, the device does not have a collection device, the treated sewage cannot be collected in a centralized manner, and the discharged sewage is not separated into dry and wet, which is not conducive to the collection and treatment of the staff.

[0004] Therefore, there is a need for a filtering device for sewage treatment to solve the problems in the prior art of being unable to automatically clean the blockage of the filter roller and the dry-wet separation of the discharged sewage. Utility Model Content
