摘要

PROBLEM TO BE SOLVED: To provide water purifying technique capable of keeping excellent water purifying action over a long period of time without being affected by the living state of aerobic microorganisms in a water area to be purified.

SOLUTION: A water purifier 10 includes a plurality of water purifying materials 12 carrying aerobic microorganisms and capable of propagating the aerobic microorganisms in the state arranged in the water area 11 to be purified and a plurality of fine air bubble generators 13 being fine air bubble supplying means for supplying oxygen-containing fine air bubbles MB into the water area 11 to be purified. A plurality of the fine air bubble generators 13 are connected to the pump P suspended from the floating island 14 floated on the water area 11 to be purified by a wire 16 to be held in water and a plurality of the water purifying materials 12 are arranged in a region where the fine air bubbles MB, which are supplied into water from the fine air bubble generators 13, can reach. Further, ventilation pipes 15 for supplying the open air to the fine air bubble generators 13 are arranged to the respective fine air bubble generators 13 from the floating island 14.
