APPARATUS FOR VACUUM HEAT TREATMENT OF ENVIRONMENTALLY HARMUFL PESTICIDE RESIDUES, EQUIPMENT FOR VACCUM HEAT TREATMENT, METHOD OF VACCUM HEAT TREATMENT AND PROCESS FO REPRODUCING ACTIVE CARBON

摘要

A material to be treated containing environmentally harmful pesticide residues is packed in an air-tight heating container 10A. Then the heating container 10A is evacuated with evacuation means 30 and the temperature in the heating container 10A is elevated to 650°C or higher. Then the inside of the heating container 10A is maintained at 650°C or higher until environmentally harmful residual organic chemicals are all decomposed. Even in case where the organic chemicals contain chlorine, a container having the material to be treated therein can be packed in the heating container as a whole and the treatment for making the chemicals harmless can be easily effected while preventing the generation of dioxin and forming no carbon dioxide.
