Disclosed are: a nutriculture system which enables the circulation of a nutrient solution while preventing the proliferation of pathogenic bacteria, and which can promote the growth of a plant effectively and steadily while preventing the change in components of the nutrient solution; and a water treatment apparatus for sterilization and purification purposes, which is compact in size. Specifically disclosed is a nutriculture system which can circulate a culture solution, which is a liquid fertilizer, between a nutrient solution tank and a cultivation bed. The nutriculture system is characterized in that a water treatment apparatus for sterilizing and purifying only the culture solution that flows through the cultivation bed is provided between the nutrient solution tank and the cultivation bed, wherein the water treatment apparatus comprises a unit having an ozone supply function for supplying ozone to the culture solution, an ultraviolet ray irradiation function for irradiating the culture solution with ultraviolet ray, and a photocatalyst-acting function for allowing a photocatalyst to act. |
