hydroponic apparatus for treating drained nutrient solution and hydroponic method using the same

摘要

The present invention relates to a nutrient solution cultivation apparatus and a nutrient solution cultivation method using the same. More particularly, the present invention relates to a nutrient solution cultivation apparatus and a nutrient solution cultivation method using the same. In the nutrient solution cultivation apparatus of the present invention, the nutrient solution is supplied through the nutrient solution supply pipe and the nutrient solution discharged from the cultivating bed flows into the nutrient solution supply pipe through the nutrient solution discharge pipe. A liquid storage tank; A circulation pump installed in the nutrient solution supply pipe for circulating the nutrient solution from the nutrient solution reservoir to the cultivation bed; An oxygen treatment unit connected to the nutrient solution reservoir and supplying oxygen to the nutrient solution discharged from the nutrient solution reservoir to increase the concentration of oxygen; And a sterilizing treatment unit connected to the oxygen treatment unit and sterilizing the nutrient solution discharged from the oxygen treatment unit by ultraviolet rays and a photocatalyst.
