METHOD FOR CIRCULATING WATER CULTURE WITH CIRCULATING WATER CULTURE SYSTEM

摘要

PURPOSE: A circulation type water culturing method is provided to collect and reuse waste nutrient solution. CONSTITUTION: A circulation type water culturing method comprises the following steps. A waste nutrient water collecting unit (100) collects waste nutrient solution from a bed for culturing. A waste nutrient solution storing unit (200) stores the waste nutrient solution supplied from the waste nutrient solution collecting unit. A nutrient solution storing unit (300) stores nutrient solution and acid. A raw water supplying unit (400) supplies raw water to the nutrient solution storing unit. A mixing unit (500) is provided with the waste nutrient solution, nutrient solution, and acid from the waste nutrient solution storing unit and nutrient solution storing unit, then mixes them, and supplies the mixture to the bed for culturing. A control unit (600) controls the operation of the waste nutrient solution collecting unit, waste nutrient storing unit, nutrient solution storing unit, raw water supplying unit, and mixing unit. The waste nutrient collecting unit comprises a water tank in which the collected waste nutrient solution is stored, and a filtering device which filters the waste nutrient supplied to the waste nutrient storing unit. The waste nutrient solution collecting unit comprises a water level control sensor. The waste nutrient solution storing unit comprises a waste nutrient solution temperature controller.
