Abstract

PURPOSE: To recover the org. matter adsorbing power of granular activated carbon to that of fresh activated carbon by instantaneously mixing waste liquors discharged by regenerating anion and cation exchange resins so that the mixed liquor is made acidic, passing the liquor through granular activated carbon after removing free carbonic acid, and regenerating the carbon.
CONSTITUTION: Waste liquor 1 discharged by regenerating a cation exchange resin and waste liquor 2 discharged by regenerating an anion exchange resin are received in receiving vessels 3, 4, respectively, and they are mixed instantaneously with ejector 7. At this time, acid 10 is added to liquor 2 so that the pH of the mixed liquor becomes ≤3. The mixed liquor of ≤3pH is allowed to flow into the top of deoxidation tower 11 to remove free carbonic acid in the liquor with air fed from a lower portion of tower 11 with blower 12, and the liquor is passed through adsorption towers 15A, 15B packed with regenerated granular activated carbon 14 to remove org. matter in the liquor by adsorption. The resulting acidic treated liquor is reneutralized with alkali to about 7pH at which electric discharge is enabled using ejector 7'. On the other hand, granular activated carbon in an adsorption tower such as tower 15C satd. with org. matter and separated from the liquor feeding cource is carried to rotary kiln through receiving vessel 19, regenerated by usual roasting, and repacked into tower 15C.
