Removable water purification device for flounder industrial recirculating aquaculture and manufacturing method thereof

The invention relates to a seawater industrial aquaculture device and especially discloses a removable water purification device for flounder industrial recirculating aquaculture and a manufacturing method thereof. The removable water purification device for flounder industrial recirculating aquaculture comprises a water tank, multiple convex support clamps, and a plate-like convenient surface filling material on which a biofilm is pre-formed. Convex parts of the convex support clamps get stuck on surrounding wall of the water tank. The plate-like convenient surface filling material on which the biofilm is pre-formed is arranged at bottoms of the multiple convex support clamps so that a platform suitable for inhabitation of flounders is formed. The removable water purification device for flounder industrial recirculating aquaculture has a simple structure, is convenient for use, can improve culture density and a yield, and utilizes real-time purification effects of a biological filter material to solve the pr
