Water purifying apparatus having scale filter

A water treatment equipment having scale filtering means, which can sterilize water by electrolysis, and is constructed in a simple structure such that the water treatment equipment can filter scales without a separate filtering mesh, is provided. A water treatment equipment comprises: a housing(100) constructed to flow water in through a water inflow part(110) and discharge water through a water discharge part(120); electrolytic sterilizing means(200) having anode plates(210) and cathode plates(220) which are alternately arranged such that the anode plates and the cathode plates are spaced from one another in a predetermined gap, and which are assembled into the housing; and filtering means(400) having a supporting plate(410) in which a through hole is formed in a water flowing direction, and which is assembled between the water discharge part and the electrolytic sterilizing means such that water directing toward the water discharge part after passing through the electrolytic sterilizing means passes through the through hole.
