Functional ecological reef for endogenous ecological restoration of river channel

The utility model discloses a functional ecological reef for river endogenous ecological restoration, which comprises an outer frame, an upper cover, a filler, a micro-nano bubble device and a microorganism releaser, the upper cover covers the outer frame, and a plurality of pull rings are arranged at the lower end of the side part of the outer frame; the filler is arranged in a cavity defined by the outer frame and the upper cover; the micro-nano bubble device and the microbial releaser are located in the filler, the outer wall of the outer frame is connected with an oxygen supply pipeline and a microbial preparation pipeline, the oxygen supply pipeline is connected with the micro-nano bubble device, and the microbial preparation pipeline is connected with the microbial releaser. Compared with the prior art, the ecological reef enclosed by the outer frame provided with the micro-nano bubble device, the microorganism releaser and the filler and the upper cover is simple in structure and has a better water bod
