[0002] In the process of daily life, sewage is a common domestic waste. The treatment of sewage is an indispensable part of the development of modern cities and rural areas. Domestic sewage contains a large amount of organic matter, nutrients, pathogens and chemicals. If it is discharged directly without treatment, it will lead to eutrophication of water bodies, cause excessive growth of algae, consume oxygen in the water, and thus destroy the aquatic ecosystem, leading to the death of fish and other aquatic organisms. In the context of global water shortage, treated sewage can be used as a renewable resource. After proper treatment, it can be used for agricultural irrigation, industrial production, landscape water use, and even in some cases, after advanced treatment, it can be used as a supplementary source of drinking water, thereby alleviating water resource pressure. Therefore, sewage treatment is of vital importance. The most common sewage treatment equipment currently available is mechanical screens; mechanical screens are a type of equipment used to filter and collect domestic sewage in daily life, and they have been widely used in the field of sewage treatment;

[0003] When the existing mechanical screen is used, it is first introduced into the sewage treatment plant through the pipeline system and enters the area where the mechanical screen is located. When the sewage flows through the mechanical screen, the metal or plastic bars on the screen will move automatically or manually to intercept and remove solid matter larger than the set spacing between the bars. The intercepted solid waste will be collected in a specific container and then dehydrated and compressed by conveyors, screw presses and other equipment to facilitate subsequent transportation and disposal. It was found in the use of the existing mechanical screen that the mechanical screen needs manual surface cleaning when cleaning, and the objects intercepted by the mechanical screen are of different sizes, resulting in a high cleaning risk factor, which leads to low working efficiency of the equipment and poor practicality.
