    • [Problem] To accelerate the discharge of gas generated during the decomposition of hydrogen peroxide from a decomposition material layer and suppress a decrease in decomposition efficiency due to the retention of bubbles of the gas in the decomposition material layer when the hydrogen peroxide is decomposed by passing water to be treated through the decomposition material layer filled with a granular decomposition material. [Solution] A hydrogen peroxide decomposition device has a configuration provided with: a decomposition tower through which water to be treated containing hydrogen peroxide is passed; a decomposition material layer which is formed by filling a granular decomposition material for decomposing the hydrogen peroxide into water and oxygen onto a support member that is disposed in the decomposition tower and has a plurality of water passage holes; a supply unit which supplies the water to be treated from the bottom side of the decomposition tower such that the water to be treated passes the decomposition material layer in an upward flow through the water passage holes of the support member; and a plurality of gas drainage flow adjustment rods which are supported on the support member disposed in the decomposition tower, extend from the lower surface of the decomposition material layer and protrude from the upper surface thereof, and are disposed at intervals within the decomposition layer.

    • PURPOSE: A stainless steel pickling sludge recovery device is provided to improve the blockage of exhaust line and productivity by separating and recovering the sludge from the pickling waste solution by using the sludge separation part. CONSTITUTION: The stainless steel pickling sludge recovery device includes: a acid sludge exhaust part(100); a waste water tank(200); and a sludge separation part(300). The acid sludge exhaust part discharges waste acid solution and the sludge from the pickling circulation tank(T) by mixing. The waste water tank contains the waste acid solution and the sludge exhausted from the acid sludge exhaust part. The sludge separation part includes: a driving part(310); a filter(320); a collecting box(330): and a elimination part(340). The driving part is installed in one side of the waste water tank. The filter is connected to one end of the driving part. The filter filters the sludge from the waste water tank. The collecting box is installed in one side of the driving part. The elimination part is installed in the other side of the driving part.
