The present invention relates to a water purification apparatus which purifies water containing foreign substances discharged from a perforated hole when a perforating process is performed. The water purification apparatus is for filtering work water used for the perforating process which includes: a coagulant body extended vertically in order for the work water injected with a coagulant can flow inside; a first supply unit supplying the work water to the coagulant body; a coagulant unit which is connected to the first supply unit and which has a second supply unit that includes a transmission pipe having multiple through holes in order for the work water to be discharged into the coagulant body; a housing for removing foreign substances from the discharged work water which has an inner space and an inflow hole in a side where the work water is induced; multiple wing units which is installed in the housing to be able to rotate, forming a discharging path inside by being laminated with each other and an inflow hole for a connection between the discharging path and the inner space of the housing; and a filtering unit having filtering means which includes a water discharging unit discharging the work water induced through the discharging path outward. |
