[0002] In the existing technology, the history of sewage treatment devices can be traced back to ancient civilizations, when people had already begun to perform simple treatment on domestic sewage to prevent the spread of diseases. However, the development of modern sewage treatment technology began in the 19th century. With the growth of population and the acceleration of industrialization, the demand for sewage treatment has increased. With the emphasis on environmental protection and the continuous advancement of sewage treatment technology, the function and performance of sewage treatment devices have also been significantly improved. In the sewage treatment process, sewage is usually deeply treated at the end of the treatment process. With the characteristics of high filtration accuracy and large water treatment volume, it is often used as the first choice for deep treatment.

[0003] However, there are many manufacturers on the market, and the equipment manufacturing structures and process levels are different. The filter components generally adopt a fixed installation method. Therefore, for the filter components, professionals need to use special tools to remove them and then clean or replace them, which not only prolongs the downtime of the sewage treatment plant, but also increases maintenance costs.
