摘要
An apparatus (U) is shown in figures 11-13 that includes a power operated vehicle (V) that supports a vertically movable frame (W) that has a confined space defining shround (X) on the lower end thereof that may be placed in sealing contact with the upper surface of a hazardous waste impoundment (Y) at a first station to permit the in situ detoxification of a desired portion of the impoundment. At least one power driven blade (Z) is rotated downwardly from within the shroud (X) into the impoundment to form a vertically extending zone (A-1) of particled material that is treated with a detoxifying agent that may be chemical, biological or heat from one or more plasma torches. Gases emitted during the formation of the particled zone (A-1) are subjected to scrub action by a liquid within shroud (X) and the liquid returned to zone (A-1). After the detoxification of a zone has been completed the apparatus (U) is moved to a succession of overlapping second stations where the above described method is repeated. The detoxified zones at the option of the user may encompass the entire impoundment, be in a configuration of a barrier that surrounds the impoundment, or a liner that extends downwardly around the periphery of the impoundment and thereunder.
