<p>PURPOSE: To provide an artificial purification pond, which is able to naturally and ecologically purify water in the pond by constituting the pond to be packed with harmless, natural and porous filter media and to remove impurities therefrom. CONSTITUTION: The pond (2) comprises a first pellet layer (220) that cultivates aerobic bacteria at a lower end of a fresh water tank and converts water in the tank into activated water, a bio-stone layer (230) that is layered on the upper side of the first pellet layer and consists of cera-soil and zeolite, a zeoli-layer (240) that is layered on the upper side of the bio-stone layer and consists of the zeolite and olivine, an air-spray layer (250) that is layered on the upper side of the zeoli-layer, has fine holes and sprays air to the holes to remove impurities from a filter-media layer, a second pellet layer (260) that is layered on the upper side of the air-spray layer and consists of particles having smaller size than that of the first pellet layer, and a rock wool (270) that is installed on each upper end of the first pellet layer, bio-stone layer, and zeoli-layer to prevent mixing between the filter-media layers.</p> |
