[0028] In the related art, when in use, air and water are mixed through an aerator system, and then filler treatment is performed to allow microorganisms to grow in designated locations to treat water quality. However, when using the microbial solidification bed on the market, an aerator system is required, which has high energy consumption, increases costs, and is large in size and heavy overall, making it inconvenient to install and move. As a result, it cannot be combined and arranged according to the direction and structure of the river channel, affecting the normal subsequent water quality treatment. It is also affected by natural conditions, flood season, flood discharge and other extreme conditions, has certain limitations, and is inconvenient to use.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a jet aeration microbial solidification bed.
