Method for decomposing pesticide residues on fruits and vegetables and disinfecting tableware through hydroxyl radical and device adopting method

Abstract

The invention relates to a method for decomposing pesticide residues on fruits and vegetables and disinfecting tableware through hydroxyl radical and a device adopting the method, and mainly aims to solve the technical problems that the conventional fruit, vegetable, tableware and medical instrument disinfection method and the conventional fruit, vegetable, tableware and medical instrument disinfection device are low in pesticide residue removal efficiency, and poor in innocent treatment effect and medical instrument disinfection effect. According to the technical scheme disclosed by the invention, the method comprises the following steps of releasing ozone into water, irradiating the water through a UVC 253.7nm mercury lamp and ultraviolet lamp module to generate singlet elemental oxygen for blowing up the water to generate a high-concentration hydroxyl radical aqueous solution for disinfecting, detoxifying and purifying the pesticide residues on the fruits, the vegetables and fresh food or disinfecting tableware and medicament instruments. The device disclosed by the invention comprises an ozone generator, an impeller, an aerator, a shell, the ultraviolet lamp module, an ultrasonic device, a water outlet, a water inlet, a water pump, an oxygen outlet, a sodium peroxide generator, a sodium peroxide collection tank, a sodium peroxide discharging pipe, a hanging mechanism, and a closing cover.

Description

technical field [0001] The invention relates to a method and device for decomposing pesticide residues in fruits and vegetables by hydroxyl radicals and disinfecting tableware, which belongs to a method that uses 253.7nm or 280nm ultraviolet light to irradiate ozone to generate hydroxyl radicals to solve the disinfection and detoxification of fruits, vegetables, fresh food, etc. , purification or tableware cleaning and disinfection, a method for cleaning and disinfecting medical instruments and an all-in-one machine thereof. Background technique [0002] Solving the biological pollution and pesticide pollution of agricultural and sideline products is the key technology to solve the entrepot trade of agricultural and sideline products in all countries in the world. So far, no country in the world has solved the problems of biological pollution and pesticide pollution of agricultural and sideline products. Technology. Therefore, the re-export trade of agricultural and sidelin...
