Plant hydroponic circulating disinfection system based on slightly acidic electrolyzed water

Abstract

The invention provides a plant hydroponic circulating disinfection system based on slightly acidic electrolyzed water. The bottom of a hydroponic tank is connected with a circulating pump through a filtering membrane; a first way of liquid conveying pipeline of an exit of the circulating pump is accessed from the upper part of the hydroponic tank through a liquid mixer, a second way of liquid conveying pipeline is connected with an available chlorine concentration meter, and a third way of the liquid conveying pipeline is connected with a water storage tank stored with electrolyzed water through an electromagnetic valve water lift pump; one end of an electrolyzed water generator is connected with a water level indicator which is inserted into the water storage tank, and the other end of the electrolyzed water generator is connected with the water storage tank; one end of an atomizing pump is connected with the water storage tank, the other end of the atomizing pump is connected with a plurality of nozzles above the hydroponic tank; and a controller is connected with the available chlorine concentration meter and an electromagnetic valve respectively. The disinfecting characteristic of the electrolyzed water is utilized, a part of the slightly acidic electrolyzed water generated by the electrolyzed water generator is mixed with a nutrient solution to be disinfected through the liquid mixer, and the other part of the slightly acidic electrolyzed water is converted to be droplets through an atomizing device to be sprayed in the cultivation room air and plant surfaces so as to disinfect the nutrient solution, the plant surfaces and the cultivation room air. The plant hydroponic circulating disinfection system based on the slightly acidic electrolyzed water can control disease transmission of the cultivation room, and is safe, harmless and low in cost.

Description

technical field [0001] The invention relates to a liquid disinfection system, in particular to a plant nutrient solution cultivation cycle disinfection system based on slightly acidic electrolyzed water. Background technique [0002] In the past 60 years, soilless culture technology for commercial production has developed rapidly worldwide. The development of soilless cultivation at home and abroad is showing a trend of gradually changing from open to closed, which is used to realize the recycling of nutrient solution, save water and fertilizer, and greatly reduce the pollution to the environment. However, the new problem brought by the recycling of nutrient solution is that the recycled nutrient solution can spread root diseases in the whole nursery, and infect other healthy plants, and in severe cases, it will cause a large number of crops to die. Therefore, the pathogenic bacteria in the nutrient solution must be eliminated before the nutrient solution is recycled to pre...

AI Technical Summary

Problems solved by technology

Ultraviolet equipment also requires a certain amount of investment, and the amount of nutrient solution processed daily is not large; the filtration methods used for disinfection are divided into two types: membrane filtration and slow sand filtration, but the cost of use in production is relatively high, and due to clogging or broken Leakage causes unstable performance, and also filters out part of the nutrient solution accumulated in salt, so it is rarely used in production

[0004] For the spray disinfection of the air environment, due to the high concentration of disinfectant used in conventional methods, it is very harmful to the staff, and it is mostly carried out when no one is working.
