Description

Technical Field

[0001] This invention relates to the field of aquaculture water treatment equipment, and more specifically, to a water circulation treatment system suitable for aquaculture. Background Technology

[0002] Aquaculture is one of the important ways to obtain aquatic resources. At present, in order to avoid oxygen deficiency and other situations, corresponding aeration pumps are usually installed in the water to increase the oxygen content in the water through aeration, thereby reducing the occurrence of death due to oxygen deficiency. However, water quality has always been a key factor affecting the aquaculture efficiency. In traditional aquaculture methods, water quality management often relies on a lot of water changes and drug administration, which not only wastes water resources but may also pollute the aquaculture environment and affect the health of aquaculture organisms.

[0003] To conserve water resources and reduce pollution, most aquaculture farms currently install corresponding water recycling systems. These systems treat wastewater and then recycle the treated water back into the aquaculture ponds. However, conventional water recycling systems only use multiple layers of filters to intercept impurities. This method is not thorough enough in terms of filtration and treatment, failing to guarantee that the water quality meets requirements and affecting the overall treatment effect. Therefore, we propose a water recycling system suitable for aquaculture. Summary of the Invention
