[0001] The invention relates to the technical field of circulating water biological tower integrated equipment for aquaculture, in particular to a circulating water biological tower integrated equipment for aquaculture. Background Art

[0002] Traditional aquaculture relies heavily on large-scale water exchange to maintain aquaculture water quality. This approach not only wastes water resources but also faces numerous challenges in today's increasingly tight water resources landscape, such as unstable water supply and a high risk of introducing foreign pathogens. Consequently, recirculating aquaculture systems are gaining increasing attention. As a key component of water purification in recirculating aquaculture systems, the performance and integrated design of biotowers significantly impact the overall system stability and aquaculture profitability.

[0003] However, most of the existing integrated equipment for circulating water biological towers are complex in structure and expensive. In addition, during the continuous operation of the water system, there will inevitably be some impurities, leftover bait, feces, microorganisms and other suspended matter in the aquaculture water. These substances will continue to pass through the filter with the flow of water. As time goes by, these debris will gradually adhere to the filter, causing the pores of the filter to gradually become smaller or even completely blocked. Summary of the Invention
