The invention discloses an infiltration reaction wall
composite material for
underwater polyaromatic hydrocarbon pollution remediation as well as a preparation method and an application method of the infiltration reaction wall
composite material, and belongs to the technical field of
underwater remediation. The infiltration reaction wall
composite material comprises a kernel, a packing layer and a shell, wherein the kernel is made of
charcoal spherical granules; the packing layer comprises 15.09-15.85% of an
oxygen release agent, 30.19-31.7% of a carbon release
raw material, 15.09-15.85% of a plastic bonding
raw material, 6.29-6.6% of a high infiltration
raw material and the balance of an
adhesive; the shell comprises 53.57-55.37% of a plastic bonding raw material, 6.43-6.64% of a high infiltration raw material and the balance of an
adhesive. The infiltration reaction wall composite material is simple and convenient to operate, low in cost and good in
repeatability, has effects of slowly releasing
oxygen and carbon, is environment-friendly, free of
pollution and small in round streaming, and has important significance in removing organic pollutants in
underwater.
