摘要 |
To treat waste containing harmful metals such as lead, cadmium, mercury, chromium, copper, nickel, zinc, etc., the waste is mixed with a treating agent containing, as the essential constituent component, solid acid(s) and/or cement and additionally a caking inhibitor, kneaded with water where necessary, then solidified by curing. Harmful metals are thereby stabilized in the thus-solidified cakes and are not released therefrom.
