ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to a soil remediation device, and more particularly to a multi-section soil remediation device having at least one section for applying a variety of soil treatment regimes. The multi-section device can be adapted to mount to a vehicle for operation in the field.
BACKGROUND OF THE INVENTION
It is widely recognized that years of industry has produced numerous environmentally hazardous sites throughout the country and the world which pose substantial health hazards to the world's population. In recent years, efforts to clean up or remediate environmentally contaminated sites have increased dramatically. Numerous methods and devices for cleaning up or disposing of environmental contamination in water, air, and soil have been devised. The magnitude of the environmental contamination is enormous in comparison to the resources made available to solve this problem.
To address the problem of environmental contamination and particularly soil contamination, a variety of soil treatment and decontamination techniques have been developed. These techniques involve, but are not limited to the application of fluids, biological agents, heat, vacuum, pressurized gases, and mechanical agitation. In order to remediate contaminated soil, it is often necessary to apply several different treatment techniques either alone or in some combination and order that is usually determined by the particular contaminate or contaminates under remediation.
As a consequence, there is an urgent need for a device that can be easily adapted in the field to apply a variety of treatment techniques. This device should be relatively uncomplicated, rapidly configured and assembled in the field, and cost effective. The present invention addresses and solves many of the above-mentioned problems associated with currently available systems.
SUMMARY OF THE INVENTION
The present invention relates to a multi-section soil remediation device having at least one section for applying a variety of soil treatment regimes. The multi-section device can be adapted to mount to a vehicle for operation in the field.
The multi-section device includes at least two soil remediation chambers each having an inlet, an outlet, and a soil conveyor for conveying soil from the chamber inlet to its outlet. The soil remediation chamber is arranged such that the outlet of at least one remediation chamber feeds soil into the inlet of at least one other remediation chamber. The multi-section device also includes a soil treatment delivery system connected to and in communication with at least one of said soil remediation chambers. The soil treatment delivery system delivers soil treatment to the soil that is conveyed within the soil remediation chamber.
It is an object of this invention to provide a multi-section soil remediation device that is relatively uncomplicated, rapidly configured and assembled in the field for applying various treatment techniques in cost effective manner to remediate environmentally contaminated sites. It is another object of this invention to provide a highly mobile apparatus for remediating environmental contaminants. It is yet another object of this invention to provide a method of remediating contaminated soil in situ and without removal or disposal of the treated or contaminated material to a remote location. It is yet another object of the invention to provide a method that is capable of remediating contaminated soils and sludge in a continuous manner.
