摘要： 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.

摘要： The present invention relates to a transmission for a vehicle, and more particularly, to a compound transmission of combining a differential gear and a continuously variable transmission, which transmits power through the differential gear and a transmission gear at a low speed and transmits the power through the continuously variable transmission and the differential gear at a high speed.According to the present invention, the shifting is performed through the differential gear unit at a low stage requiring large torque and low rpm and performs the shifting through the continuously variable transmission at a high stage requiring relatively small torque and high rpm to provide optimum shifting efficiency by collecting only advantageous of the respective units.

摘要： 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.
