Description

Multistage filtering device of circulating water culture system Technical Field The utility model relates to the technical field of circulating water culture, in particular to a multistage filtering device of a circulating water culture system. Background In recirculating aquaculture systems, stabilization and purification of water quality is critical to the healthy growth of the farmed organisms. Existing recirculating aquaculture systems typically employ various filtration devices to remove solid particulates and organics from the water. However, many conventional filtration devices lack an effective self-cleaning function during the filtration process. As filtration proceeds, impurities in water gradually adhere to and accumulate on the surface of the filter screen or filter material, resulting in clogging of the filter screen pores, thereby significantly reducing filtration efficiency and water treatment capacity. In order to restore the filtering effect, manual cleaning or filter material replacement must be performed regularly, which not only increases the labor intensity and the operation cost of cultivation management, but also may require suspension of filtration in the cleaning process, affect the continuous operation of the system, and even cause water quality fluctuation due to untimely cleaning, thereby adversely affecting the cultivated living things.
