Problems solved by technology

[0006] During the use of the existing direct drinking water system, there is a problem that the water body will re-grow bacteria and other microorganisms due to long-term storage after the water purification system is intermittently used or not used for a long time. It can only be drunk after being fully sterilized, otherwise it may affect the health of the drinker

Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific embodiments.

[0026] According to attached figure 1 to attach Figure 5 As shown, the ultraviolet disinfection device described in this embodiment is mainly composed of a water flow detection device K1, a coarse filtration module 1, an intermediate filtration module 2, an ultrafiltration module 3, an ultraviolet disinfection module 4, and a water outlet control valve connected in sequence. K2 composition. The coarse filter module 1 can use a PP cotton filter element to filter large particles of impurities such as sediment and rust, as well as floating objects, sediments, and flocs in the water supplied by the water tank on the roof. The middle filter module 2 can use an activated carbon filter element to absorb organic matter such as residual chlorine in water, odor, color, and strong carcinogen chloroform, etc., and has an adsorption effect on organic matter in water and heavy metals ...

Abstract

The invention provides an ultraviolet disinfection method and an ultraviolet disinfection device capable of running quickly and disinfecting fluid efficiently. In the method, fluid or deposited liquid in a bending fluid pipeline is irradiated fully by ultraviolet for 0.5 to 3 seconds, and the ultraviolet radiation of the ultraviolet is improved by using a low-pressure and high-strength ultraviolet lamp, so that the ultraviolet radiation dose of the fluid is more than 10 mJ / cm<2>(mW s / cm<2>) to disinfect the fluid fully, wherein the current of the low-pressure and high-strength ultraviolet lamp is between 0.3 and 8.0 A, and the current density of the lamp is between 0.3 and 1.5 A / cm<2>. Simultaneously, the cold end of mercury is arranged at the bottom of the ultraviolet lamp and is heated,and heat is preserved, so that the temperature is controlled to be between 40 and 50 DEG C; and the ultraviolet lamp is started instantly so that the ultraviolet illumination is close to the maximum value quickly so as to meet the requirement of the ultraviolet radiation dose of the fluid and ensure quick, efficient and full disinfection.

Description

technical field [0001] The invention relates to the technical field of ultraviolet disinfection equipment, in particular to a fast-running and highly efficient disinfection ultraviolet disinfection method and a device thereof. Background technique [0002] Today's society and economy are developing rapidly, and people's quality of life has been rapidly improved. At the same time, the issue of drinking water, which is related to people's health, is becoming the focus of widespread attention from all walks of life. People have higher and higher requirements for the quality of drinking water. The drinking water treated by the water plant will cause secondary pollution due to the influence of pipelines and other influences during the transportation process. Ordinary tap water cannot be directly drunk. Very necessary. [0003] Ultraviolet disinfection is a disinfection technology based on modern optics, physical chemistry, biology, and epidemiology. The 253.7nm ultraviolet rays...
