Abstract
The incineration of wood wastes contaminated with chlordanes is reported. Tests were carried out by using combustion pipe with a electric furnace in laboratory. Under condition above 900°C with a residence time of 1 sec, the removal efficiency for chlordanes exceeded 99.9998% as calculated from residues at the levels of their detection limits. However, under thermal condition below 700°C, the destructions of chlordanes were incomplete.
Chlorinated hydrocarbons such as chloroprene, chloroform, 1, 4-dichloro-2-butyne and tetrachloroethylene were formed by the pyrolysis from chlordanes, and these compounds are considered to transform into chlorinated aromatic hydrocarbons such as chlorobenzenes, chlorophenols and PCBs by cyclization.
