Title:
OZONE OXIDATION APPARATUS
Document Type and Number:
Japanese Patent JP3419765
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ozone oxidation apparatus which can efficiently remove pollutants contained in fluid by dispersing fine air bubbles into the fluid to increase the dissolved air concentration, and then maximizing an oxidative effect by the catalytic action of momentary oxygen bubbles when ozone is mixed with the pollutants in the fluid uniformly.
SOLUTION: A fluid that has been brought into contact with fine air bubbles in a bubbles generator 200 and a bubble generating tower 300 is brought into contact with ozone gas in an ozone contactor 500 and an ozone oxidizer 600 to maximize the oxidative effect by the direct and indirect reactions of ozone. Residual ozone gas is repeatedly applied to a recontact process by a pressure control pipe 530, therefore it is not discharged outside. Floating pollutants are removed by a skimmer 630, and then the residual pollutants are filtered by a filter 700. Only the cleaned filtrate is discharged.
