This invention provides granular materials for environmental improvement that, after being introduced into a body of water, initially float to promote the attachment and dispersal of microorganisms, and then naturally sink to improve the bottom sediment. [Solution] This granular material is formed by mixing a base material containing iron powder and carbon powder with a lightweight porous material derived from plants and then press-molding it. The granular material has a fine void structure inside, and initially floats on the water surface or near the surface due to the buoyancy of the void structure and the lightweight porous material derived from plants.

Without using any special power or equipment, it can gradually achieve both "diffusion and microbial attachment in the surface layer" and "improvement of water and sediment quality in the bottom layer" simply by being added. Furthermore, by using recycled materials such as used hand warmers as the base material, it is possible to provide a resource-recycling material with a low environmental impact.

This invention proposes a protective device and method for preventing the spread of pollutants in aquatic ecological environments, belonging to the field of ecological protection. The method includes the following steps: a water diversion channel is set up on one side of a river channel; anchor points are set up on the riverbank on the same side of the water diversion channel; a guide fluid is connected to the anchor points and allowed to float freely on the river surface; when the guide fluid is inclined at an acute angle relative to the river's flow direction, its end is anchored; the guide fluid is used to change the river's flow trajectory, causing floating debris in the water to bypass the water diversion channel.
