Electrokinetic soil desalinization system and method

摘要

A system for electrokinetic desalinization of soil may include at least one cathode including a hollow cathode tube perforated along its length to allow liquid water to pass through the cathode tube from an exterior thereof to an interior thereof, and a cathode conductor extending along an exterior surface of the cathode tube; at least one anode including a hollow anode tube perforated along its length to allow liquid water to pass through the anode tube from an exterior thereof to an interior thereof, and an anode conductor extending along an exterior surface of the anode tube; a make-up water line communicating with the interior of the anode tube; an anode discharge line communicating with the interior of the anode tube; and a cathode discharge line communicating with the interior of the cathode tube.

1. A system for electrokinetic desalinization of soil, the system comprising:
a first bore-hole formed below the surface of the soil; a second bore-hole formed below the surface of the soil; a cathode including a hollow cathode tube perforated along its length to allow liquid water to pass through the cathode tube from an exterior thereof to an interior thereof, the cathode tube located within the first bore-hole, and a cathode conductor wrapped around and supported on an exterior surface of the cathode tube along an entire length of the cathode conductor within the first bore hole; an anode including a hollow anode tube perforated along its length to allow liquid water to pass through the anode tube from an exterior thereof to an interior thereof, the anode tube located within the second bore-hole, and an anode conductor wrapped around and supported on an exterior surface of the anode tube along an entire length of the anode conductor within the second bore hole; the first bore-hole and the second bore hole each including granular, electrically conductive material, the granular, electrically conductive material backfilling the first bore-hole and surrounding the exterior surface of the cathode tube, and backfilling the second bore-hole and surrounding the exterior surface of the anode tube; a make-up water line communicating with the interior of the anode tube; a first discharge line communicating with the interior of the anode tube; and a second discharge line communicating with the interior of the cathode tube.
