Embodiment Construction

[0013] The method for disinfecting, detoxifying and purifying water using hydroxyl radicals in this embodiment comprises the following steps: first, the ozone produced by the ozone generator is released into the treated water through the aerator, and then stirred by the wave wheel in the treated water High-concentration ozone water is generated in the water, and then the high-concentration ozone water is irradiated by the UVC253.7nm mercury lamp ultraviolet lamp module or the deep ultraviolet DUV LED280nm LED ultraviolet lamp module to generate singlet atomic oxygen, and the singlet atomic oxygen pulls the water apart to generate high-concentration ozone Hydroxyl free radical aqueous solution continuously disinfects, detoxifies and purifies drinking water to make it meet the sanitary standard of drinking water and discharge it; at the same time, the oxygen generated by the ozone generator is generated by the sodium peroxide generator to generate sodium peroxide and then supplied...

Abstract

The invention relates to a method and a device for disinfecting, detoxifying and purifying water by using hydroxyl radicals. The method and the device mainly solve the technical problems that the existing water treatment method and the existing water treatment device cannot remove residual carcinogenic substances in water, and cannot remove overproof heavy metal and organic compounds. The method adopts the technical scheme that the method comprises the following steps that ozone is released to treated water; singlet-state atomic oxygen is generated through radiation of a plurality of mercury lamp ultraviolet lamp modules at UVC (ultraviolet C) 253.7nm or a plurality of LED (light-emitting diode) ultraviolet lamp modules at DUV (deep ultraviolet) LED 280nm; drinking water is continuously disinfected, detoxified and purified, so that the drinking water reaches a sanitary standard for domestic drinking water, and then is discharged; or reclaimed water of waste water is recycled; and zero discharge is reached. The device using the method comprises an ozone generator, an impeller, an aerator, a housing, the ultraviolet lamp modules, an ultrasonic device, a water inlet, a water outlet, an oxygen outlet, a sodium peroxide generation machine, a sodium peroxide collection tank and a sodium peroxide discharge pipe.

Description

technical field [0001] The invention relates to a method and device for disinfecting, detoxifying and purifying water by using hydroxyl radicals, which belongs to a method for disinfecting, detoxifying, purifying drinking water or treating waste water by irradiating ozone with 253.7nm or 280nm ultraviolet light to generate hydroxyl radicals A method and device for disinfecting, detoxifying and purifying reclaimed water. Background technique [0002] About 50% of China's water sources are polluted. The Ministry of Environmental Protection announced the "2012 China Environmental Status Bulletin" on June 4, 2013. In 2102, more than 30% of the rivers and more than 50% of the groundwater did not meet the standards. At present, the qualification rate of drinking water in our country is low. Less than 11% of people drink water that meets the national health standards, and 65% of people drink water that is turbid, bitter, salty, fluorine-containing, arsenic-containing, or industrial...
