Through environmentally friendly ceramics, which re-created into a new ecosystem, combined with 3D printing technology.And through the modular structure,it can adapt to the size and depth of rivers in various regions.Place a wetland system on the resuscitation basket on the surface of the water to provide nutrients, and design a coral reef structure in the water to allow shrimp,shellfish and other organisms to have habitat and at the same time increase the water circulation.
