To provide a new water purifying method effective all over the water area from a bottom layer to a top layer by utilizing, in large scale, natural energy or aquatic plants for which running costs are not required, in lakes or marshes as an inner water surface or on the surface of the sea of a raising field.
A circulating water current is basically caused to flow with a set of a pair of pumps for sucking top layer water and discharging it to the bottom layer and for sucking bottom layer water and sprinkling it over the surface of water, a windmill-driven simplified pump is combined with a large-scaled artificial vegetation floating island of aquatic plants which are enriched in nutrition and improve water purifying capabilities, thereby providing a total water purification system.
