Patent ID: 8512557

Claim:
A radon reduction apparatus for groundwater having a disinfection means, comprising: an agitation space forming body that groundwater fed through a groundwater feed pipe passes through before inflow into a groundwater storage tank and that forms a water turbine installation space whose top portion is not filled with groundwater; a water turbine located in the water turbine installation space to be rotated by groundwater when the fed groundwater falls, is run against a bottom and scattered; an oxygen supply means supplying oxygen to groundwater before inflow of the groundwater to the agitation space forming body; a ventilating fan that is rotated by receiving rotary power of the water turbine and that is connected to the water turbine installation space to discharge air of the water turbine installation space; an antiseptic solution supply means supplying antiseptic solution to be mixed with the groundwater, and wherein an agitation space, in which a predetermined amount of fed groundwater is delayed while going through the agitation space before inflow into the groundwater storage tank, is formed on a lower portion of the water turbine installation space in the agitation space forming body, and an agitation screw located in the agitation space to stir the groundwater and the antiseptic solution inside the agitation space by being rotated by rotary power transmitted from the water turbine is further included, and wherein in the antiseptic solution supply means, the antiseptic solution automatically flows in the groundwater feed pipe by an orifice, and in the oxygen supply means, air automatically flows in the groundwater feed pipe by the orifice, and wherein a partition is installed in the agitation space, thereby the groundwater flowing in the agitation space is discharged in the agitation space after flowing along a predetermined route.
