Fuel sludge treatment method, especially for leaded gasoline storage tank sludge

摘要

A sludge treatment technique adapted for separating volatile liquid hydrocarbons and/or water from sludge solids in a horizontal enclosed tank having a supported bed of filter particles. Liquids are permitted to drain and evaporate under controlled conditions and a removable top closure permits exposure of sludge solids to ambient U-V radiation and weathering conditions whereby lead-containing sludge is detoxified to environmentally acceptable levels.
