The present invention relates to a biodegradable starch ring and a method for decomposing the chemical in soil using the same, the starch ring of the present invention prepared by combining the starch with a biodegradable curing agent can be stored for a long time, such as small spheres or polyhedrons It is easy to transport in the form and is easy to spread evenly over the large sedimentation basin, and its specific gravity is more than 1.1, which is heavier than water, so it settles quickly to the bottom of the sedimentation basin. By enhancing, the explosives present in the sedimentary deposits can be effectively removed. |
