[0002] In the aquaculture industry, the quality of aquaculture water is crucial to the growth and health of the cultured organisms. With the continuous expansion of the aquaculture scale and the increase of the aquaculture density, the content of particulate matter in the aquaculture water gradually increases. These impurities not only affect the transparency and dissolved oxygen content of the water body, but also contain bacteria and viruses that can harm the cultured organisms.

[0003] Currently, there are some shortcomings in the aquaculture water filtration equipment on the market. For example, the filtration precision of some filtration equipment is not enough, which cannot effectively remove the small particulate matter in the water body; some equipment is bulky, inconvenient to install and maintain, and occupies a large space; some equipment is prone to clogging during filtration, which requires frequent cleaning and replacement of filter screens, increasing labor costs and equipment maintenance costs. Therefore, it is of great practical significance to develop an efficient, convenient and high-precision aquaculture water filtration equipment. SUMMARY
