PROBLEM TO BE SOLVED: To provide a method for controlling a water-quality-purifying apparatus, which can be operated in a series of routine processes. SOLUTION: The water-quality-purifying apparatus 1 comprises a medium 10 and a floating body 20 assembled separably from each other, which are respectively carried to a river system of a to-be-purified object. The medium 10 has an optionally selected standard, and hydrophilic plants 30 are planted in a nursery. The floating body 20 has a specification associated with the medium 10, and is capable of holding the medium 10 in a submerged state in a specified depth. The floating body 20 and the medium 10 are respectively carried to the river system for purification of the water by means of the plants 30. The medium in which the plants 30 are grown is separated from the floating body 20, and the plants 30 grown in the medium 10 are removed therefrom, and carried out of the water system. The medium 10 from which the plants 30 have been collected is recovered. The plants 30 are planted again in the nursery, and carried to another water system and combined with any one floating body 20. |
