The present invention relates to a system for recovering and recycling nutrient solutions, and more specifically to a system for recovering and recycling nutrient solutions, comprising: a nutrient solution recovery tank communicated with a cultivation tank where nutrient solutions are supplied, recovering and storing the nutrient solutions discharged therefrom; a filtering unit communicated with the nutrient solution recovery tank and filtering the nutrient solutions stored therein; a disinfection processing unit connected to a rear end of the filtering unit and electrifying the filtered nutrient solutions to conduct sterilization and insecticide of the nutrient solutions; and a mixing tank for adjusting the concentration of the nutrient solutions through the sterilization and insecticide from the disinfection processing unit and transferred back to the cultivation tank. According to the present invention, the system for recovering and recycling nutrient solutions for electrifying the nutrient solutions remaining in the crop cultivation tank to conduct sterilization and insecticide and recycles the nutrient solutions to be reused, thereby having effects of: reducing the use of fertilizers; reducing soil and water contamination since the remaining nutrient solutions are not processed as wastewater; and allowing users to easily install the system since the sterilization and insecticidal-treatment processes are remarkably simple, and thus the system can be utilized widely in farms at a relatively low cost. |
