ION-RELEASING ARTIFICIAL FISH REEF MIXING AND SOLIDIFYING FINE STEEL PARTICLE OR CUTTING DEBRIS DISCHARGED DURING CUTTING OF IRON

摘要

PROBLEM TO BE SOLVED: To provide an artificial fish reef that is effective in preventing sea desertification and restoring from sea desertification and that maintains the elution of iron ions for a long time.SOLUTION: The artificial fish reef in which iron particles, i.e., waste discharged by the steel industry, are utilized and solidified using sand cement is sunk to the sea bottom of a fishing ground deteriorated as the natural environment has been destroyed. Iron ions are eluted over a long period of time for the implantation and growth of seaweed. As a result, a natural environment where sea urchins, cancers and fish can live can be recovered.
