CONSTITUTION: The underground water and rainwater purifying apparatus of a water curtain cultivation facility includes an upper part(100), a body part(200), a first perforated plate(210), a central shaft(230), a second perforated plate(240), a cap(250), and a lower part(300). The upper part includes an inlet(110) through which used underground water and rainwater are introduced. The body part is combined with the upper part. The first perforated plate includes a plurality of holes(211), and the holes are in connection with a plurality of filters(212). A vertically movable wing(231) is installed at the central shaft and is being moved along a guide. The second perforated plate is fixed to the lower side of the central shaft and is positioned at the upper side of the first perforated plate. The cap blocks the supply of water in case of the floatation of the second perforated plate. The lower part includes an outlet(310), and filtered water is discharged through the outlet.
