Arsenic adsorption device in groundwater using wind force

摘要

The present invention relates to an arsenic adsorption apparatus in groundwater using wind power, which comprises: a torque generating unit installed on a tower installed on the ground in a soil and groundwater-contaminated area and having a shaft axially rotated by receiving a flow pressure of air flowing in atmosphere; a compression unit operated by receiving a rotation force of the shaft to suck air therearound so as to discharge the same to the outside; a connection pipe connected to the compression unit, and receiving the air discharged from the compression unit to induce the same to a demand place; a chamber for receiving and accommodating the air induced through the connection pipe; and an air ejection unit having a porous pipe buried in the ground of a contaminated point to be fixed, having a lower end thereof reaching a groundwater layer, formed with a plurality of air discharge holes, and receiving the air from a chamber to eject the same to the surroundings. The arsenic adsorption apparatus in groundwater using wind power of the present invention has a method of oxidizing divalent iron distributed in soil to trivalent iron by constantly supplying air into a groundwater layer or an unsaturated soil layer contaminated by arsenic and allowing iron oxide to absorb the arsenic, thereby very easily and effectively removing the arsenic, and rarely consuming energy and being eco-friendly since wind power is used for air supply, particularly.
