PURPOSE:To completely decompose liquid organic halides such as PCB etc. to make them harmless, by making in advance liquid organic halides such as PCB etc. into a solid composition having specific composition, and then heating it to high temperature, causing vaporized organic halides being released to be burnt with oxygen. CONSTITUTION:Prior to burning treatment, liquid organic halides are in advance made to form a solid composition composed of liquid organic halides, calcium hydroxides and/or magnesium hydroxides, water-soluble polymers, organic acid metallic salts, silicates, and extending agents. The solid composition wherein liquid organic halides are fixed is heated to high temperatures in the presence of or in the absence of oxygen to cause vaporized organic halides to be released from said solid composition. When said vaporized organic halides are burnt at high temperatures with oxygen, they are completely decomposed, with the result that organic halides themselves can not be detected in the combustion flue gases and also can not be detected in the solid composition. |
