A water-lifting aeration water quality improving device enhanced through bubble cutting and bio-contact oxidation

A water-lifting aeration water quality improving device enhanced through bubble cutting and bio-contact oxidation is provided. A lifting center cylinder is disposed in a cabin body of a bio-contact oxidation unit. The cabin body, the lifting center cylinder and a rising cylinder unit are coaxially arranged. A chamber between the cabin body and the lifting center cylinder is a filler filling chamber. The filler filling chamber is provided with a plurality of double-layer punched plates along the axial direction. The double-layer punched plates partition the filler filling chamber. A resistancereducing slot is disposed between two layers of each double-layer punched plate. A plurality of meshed ball shells are disposed in the filler filling chamber and contain a filler. The device combinesa bubble cutting aeration process and a bio-contact oxidation process, oxygen-rich water aerated by a water lifting aerator is brought into contact with a bio-contact oxidation gear in a process thatwater is lifted by the wate
