Ultraviolet bacteriostatic method and purified direct drinking water bacteriostatic method

Abstract

The invention discloses an ultraviolet bacteriostatic method and a purified direct drinking water bacteriostatic method. The ultraviolet bacteriostatic method includes an ultraviolet light source and is characterized in that the method includes the following steps: the ultraviolet light source is used for irradiating the purified water with an irradiation dose much lower than the normal rated germicidal irradiation dose, so as to realize antimicrobial treatment. As the ultraviolet light radiation dose is much lower than the normal rated germicidal irradiation dose, and a low ultraviolet light radiation dose can effectively inhibit the reproduction of bacteria, the bacteriostatic effect is achieved; for purified water or water subjected to antimicrobial treatment, a low ultraviolet light radiation dose can effectively prevent breeding of bacteria, and does not cause secondary pollution to the purified direct drinking water; in addition, as the ultraviolet light radiation dose is much lower than the normal rated germicidal irradiation dose, the ultraviolet light radiation time can be effectively shortened, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a disinfection device, in particular to an ultraviolet ray bacteriostatic method and a bacteriostatic method for purifying direct drinking water. Background technique [0002] With the rapid development of modern society and economy, water pollution is becoming more and more serious, and people's concerns about the safety of direct drinking water for domestic use are also increasing day by day. The direct drinking water referred to in this article is generally the water that has been filtered and purified or the purified water that appears on the market and the bottled water that comes with the water dispenser. Generally speaking, the water that has been filtered and purified by multi-stage membranes can guarantee people’s daily safe drinking. But the problem is that in real life, purified drinking water cannot be drunk in time and stored in water tanks or buckets. Purified drinking water has more suitable conditions for bacter...
