A WATER PURIFILER FOR UNDERGROUND WATER

An apparatus for purifying groundwater is provided to use the ground water as drinking water for domestic animals, through a purifying process using filters and an adsorbing process using activated carbon. A first purifying unit(20) purifies water in a multi-step, by using plural purifying filters(21) installed on a water supply pipe(12). A second purifying unit(30) includes a supply space(31), activated carbon(32) filling the supply space, and a tank(33) positioned above the supply space. A feeding hose(22) connected to ends of the purifying filters is connected to the supply space. Air is supplied to the tank through an air supply unit(34). A drain is connected to a water discharge port(36) installed at a portion of the tank to supply water to a water tank(40). The water tank is connected to the drain. An ozone sterilization light(41) is installed in a lower portion of the water tank. The water tank supplies water through a purified water supply pipe. Further, an open-close cover(14) is installed by forming a projection part(15) at an upper side of the first purifying unit and the second purifying unit.
