Abstract

PURPOSE: To remove the chromaticity and COD in the treating liquid with micro ozone bubbles produced by dissolving high-concn. ozones under pressurizing to part of the treating liquid added with a flocculant, and releasing the same into the treating liquid under decreased pressure.
CONSTITUTION: In an agitating tank 4, a suitable amount of a flocculant is added to the raw treating liquid such as night soil desorbing liquid and the liquid is fed into a separating tank 1. On the other hand, the liquid of 20W50% the volume of the raw treating liquid is drawn out from the separating tank 1 by means of pipe lines 10, 11. High-concn. gaseous ozone is injected into the raw liquid with an injector 6, and the liquid is pressurized in a tank 8 to enhance the solubility of ozones and accelerate the reaction. Next, the pressurized liquid is pressure released in the separating tank 1 and the micro bubbles of the produced gaseous ozone are brought to contact with the raw treating liquid, whereby the raw liquid treatment is accomplished.
