Description

Technical Field

[0001] The utility model relates to the field of aquaculture, in particular to a purification device for aquaculture tail water used in aquaculture. Background Technique

[0002] Aquaculture tail water refers to the aquaculture water generated during the aquaculture process, which contains various pollutants from feed, aquatic product feces, bottom mud and sand, etc., mainly nitrogen, phosphorus and other elements.

[0003] In the prior art, when treating aquaculture tail water, it is necessary to inject the aquaculture tail water into a sedimentation tank for sedimentation. However, there is no filtration before injecting it into the sedimentation tank. Large particle impurities may directly enter the sedimentation tank, increasing the load of the sedimentation tank, requiring more treatment time and chemical agents to ensure the effective removal of impurities, thus increasing the treatment cost. Moreover, if large particle impurities directly enter the sedimentation tank without pretreatment, they may block some parts of the sedimentation tank, affecting the sedimentation effect and reducing the overall treatment efficiency. Large particle impurities may cause abrasion to pipelines and equipment during the flowing process, shortening the service life of the equipment.

[0004] Therefore, we propose a purification device for aquaculture tail water used in aquaculture. Content of the Utility Model
