An automatic oxidation-reduction treatment system, characterized in that it comprises introducing oxygen or hydrogen to a agitation vessel under reduced pressure through a nozzle to feed the gas into a solution having a reduced pressure and reduce the size of a bubble by agitation under reduced pressure, subjecting the resultant solution to high speed agitation by means of a water-jet pump under reduced pressure to further reduce the size of a bubble, and rapidly feeding the resultant bubbles into an agitation vessel under pressure to dissolve the bubble while still further reducing the size of a bubble under pressure by instantaneously cutting and pressing it, thereby convert the solution into a colloidal state. The above system allows the achievement of a strong oxidative or reductive action in a short time and continuation of the action stably for a long period of time, due to the oxidation or reduction in the state of a gas-liquid colloid by oxygen or hydrogen, which results in the treatment being free from imbalance or unevenness, leading to, for example, the easiness and simplicity in the removal of iron rust. As a result, the system can be suitably used in the fields requiring an oxidation treatment, such as steel, shipbuilding, automobile, ceramics, cement, foods, environment, medical care and ocean, and, in a field requiring the reduction treatment of an oxygen colloid, the system can provide a treated fluid containing a reduced colloid in a maximum amount as much as 6 tones per minute. |
