Abstract: Provided is a method of restoring arsenic-contaminated soil. In the present invention, arsenic may be easily separated from soil particles by washing the arsenic-contaminated soil by using a basic solution and simultaneously irradiating the soil with ultrasonic waves. Also, since iron oxide and manganese oxide are exposed to the basic solution by dissolving a portion of the surface of a silicate mineral using the basic solution, a residual form of arsenic may be removed.

Abstract: The present invention provides a method of remediating contaminated soil with heavy metal using a microorganism of Sporosarcina sp. Contaminated soil is inoculated with the Sporosarcina sp. KM-01 (Sporosarcina pasteurii KM-01) strain includes a base sequence of SEQ ID NO. 1, the Sporosarcina sp. KM-07 (Sporosarcina pasteurii KM-07) strain includes a base sequence of SEQ ID NO. 2, and the Sporosarcina sp. KM-12 (Sporosarcina pasteurii KM-12) strain includes a base sequence of SEQ ID NO. 3. The strains are capable of producing urease.

Abstract: Provided is a particle separation apparatus. The particle separation apparatus for separating soil by particle size in a wet-type separation manner includes a body unit providing a space in which a mixture of the soil and water is received to flow vertically, a screen unit coupled to the inside of the body unit to separate the soil by the particle size from the mixture that flows vertically, and a space adjustment unit coupled to a lower portion of the body unit to cover the lower portion of the body unit, the space adjustment unit adjusting a volume of a lower space of the body unit to allow the mixture to repeatedly flow in a vertical direction.

Abstract: Provided is a banking structure using a rock producing acid drainage. The banking structure includes a banking layer including the rock having acid drainage production possibility and an inhibitor for reducing acid drainage production potential of the rock, a capillary breaker layer stacked between a lower portion of the banking layer and an underground water level surface to prevent underground water from being introduced into the banking layer by a capillary phenomenon, and a finishing layer stacked on an upper portion of the banking layer according to a use thereof.
