Problems solved by technology

[0013] Also in the hydroponic cultivation sterilizing device of Patent Document 2, since only ozone supply is used to sterilize, the culture solution is easily acidified and pH control is difficult.
In addition, since the ozone concentration is high, there is a possibility of ozone damage as in this document 1.

Embodiment

[0098] If the water treatment device in the present invention is used, general live bacteria can be reduced, and vegetables and fruits can last longer. For general living bacteria, coliform bacteria, and E. Coli that propagate in the plants of green onions, a comparative measurement is carried out with or without the device of the present invention. As a result, according to the standard plate culture method, general viable bacteria were 1,100 / g and 12,000 / g in Comparative Example as result (1), and 300 or less / g and 2,700 / g as result (2). Still have the situation of device of the present invention, generally live bacteria is few. It has been known conventionally that vegetables, fruits, etc. will last longer if the general viable bacteria are reduced, and it has been proved that the general viable bacteria are reduced by using the device of the present invention.

Abstract

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.

Description

technical field [0001] The invention relates to a nutrient solution cultivation system and a water treatment device for nutrient solution cultivation of plants, in particular to a nutrient solution cultivation system and a water treatment device for sterilization and purification suitable for hydroponic cultivation. Background technique [0002] Conventionally, as such a hydroponics system, for example, Figure 14 Nutrient solution circulation system 1. The nutrient solution circulation system 1 includes a nutrient solution container 2 and a cultivation bed 3 for cultivating plants. The nutrient solution container 2 and the cultivation bed 3 are connected through a supply pipe 8 and a return pipe 9 . In this nutrient solution circulation system 1 , the nutrient solution 10 in the nutrient solution container 2 is supplied to the cultivation bed 3 through the supply pipe 8 and stored in the nutrient solution container 2 through the return pipe 9 . [0003] Figure 15 The nu...
