Abstract
PURPOSE: A treatment method for waste water in which waste water containing high concentrations of oxygen-demanding substances such as organics is effectively oxidized and at the same time copper ion is effectively recovered for reuse.
CONSTITUTION: In the treatment of highly conc. waste water, the waste water through the line 1 and the storage tank 2 is mixed with a copper ion-concentrated recovery liquor from the line 28 and an ammonia ion-forming substance supplied from the line 37 and then sent to the reaction tower 6 through the heat exchanger 5 by the pressure-rising pump 3. Also, part of oxidized liquor subject to vapor-liquid separation under high pressure is drawn out of the bottom of the vapor-liquid separator 7 and added to the aforesaid waste water and also air necessary for wet oxidation is supplied to the reaction tower by the compressor 4. The waste water so treated in the reaction tower 6 is then introduced into the vapor-liquid separator 7, where the remainder of the oxidized liquor is sent to the cyanogen decomposer 12 and then the pH regulator 15. In the Fig. 18 denqtes a degassing tower, 22 a copper removal tower, 26 a supernatation tower, and 32 a salination tower.
