<P>PROBLEM TO BE SOLVED: To provide integrated control means for temperature adjustment and water purification for a nutrient liquid for hydroponic culture. <P>SOLUTION: A nutrient liquid treatment apparatus (20) is a device for purifying the nutrient liquid in a hydroponic system (10). The nutrient liquid treatment apparatus (20) includes: a water purification unit (60) having a heat pump (21) for adjusting the temperature of the nutrient liquid, an electrode pair (64 and 65) for generating streamer discharge in the nutrient liquid, and a power supply (70) for applying the direct voltage to the electrode pair (64 and 65), and configured to generate hydrogen peroxide in the nutrient liquid by the streamer discharge; and a controller (41) for controlling both the temperature adjustment of the heat pump (21) and the purification motion of the water purification unit (60). <P>COPYRIGHT: (C)2012,JPO&INPIT |
