Eutrophic water body purification and remediation device

The invention discloses a eutrophic water body purification and remediation device, relates to the technical field of water body purification, and solves the problems that aquatic plants cannot be moved conveniently and the utilization rate of the aquatic plants is reduced after in-situ purification is completed. The device comprises a box body, and a driving piece used for intermittently drivingthe device to move is arranged in the box body; a floating plate is connected on the bottom of the box body, and a plurality of floating bed groups are connected on the floating plate; each floating bed group comprises a horizontal floating bed, a filter cartridge and a bottom box which are sequentially connected from top to bottom, a microbiological group is arranged in the bottom box, and aquatic plants connected with the floating bed are arranged in the filter cartridge. The effects that the device is conveniently moved to another water area after in-situ purification is completed, and theutilization rate of aquati
