Embodiment Construction
[0039] The present invention provides an ultraviolet-ozone combined disinfection method for nutrient solution, and the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0040] figure 1 It is a schematic flow chart of the ultraviolet-ozone combined nutrient solution disinfection method. The liquid to be disinfected in the nutrient solution pool 1 is sucked into the pipeline by the stainless steel corrosion-resistant self-priming pump 2, and the flow rate is 20m 3 / h; the nutrient solution enters the screen filter 3, and passes through a 120-mesh screen to filter out the ozone-depleting organic matter in the nutrient solution, reducing the ineffective loss of ozone, and reducing the opaque impurity content in the nutrient solution, improving the nutrient solution. The transmittance improves the ultraviolet sterilization effect; the filtered nutrient solution flows into the 4 venturi-type jets 5 through the ...
