Document Type and Number:
WIPO Patent Application WO/2007/108468
Kind Code:
A1
Abstract:
[PROBLEMS] To provide novel means for simultaneous treatment of heavy metals and organochlorine compounds contained in dredged soil, etc. [MEANS FOR SOLVING PROBLEMS] There is provided a soil treating apparatus including at least a direct heating type heating oven (No. 2 kiln) capable of reductive pyrolysis of general organic matter and removing of heavy metals and an incomplete combustion burner (furnace) capable of reductive pyrolysis of vaporized organochlorine compounds (dioxins) and heating of the interior of the direct heating type heating oven. Any vaporized organochlorine compounds are decomposed by the use of flame (1000°C or higher) from the incomplete combustion burner, and reductive pyrolysis of general organic matter and removing of heavy metals are carried out inside the direct heating type heating oven (500° to 800°C). Accordingly, any organochlorine compounds, other organic matters, heavy metals, etc. contained in soil can be treated, and the internal temperature of the heating oven can be held relatively low.
