Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and typical embodiments.

[0035] exist figure 1 Among them, in the current production of bottled water, the traditional treatment method of combining chemical disinfection and physical disinfection is adopted. The raw water is firstly pretreated by pretreatment device 1 in the water factory, including flocculation, sedimentation and sand filtration, etc., and then In the disinfection treatment system 2, chemical disinfection treatment and physical disinfection treatment are carried out by adding chemical disinfectants and preservatives, ultraviolet radiation and other methods, and then filled into barrels to make barreled drinking water products, which are released after storage and transportation. User water supply.

[0036] exist Figure 2-Figure 6 Among them, the main body of the composite and separate physical disinfection device for barreled drinking water of the...

Abstract

The invention relates to a composite and separable physical disinfection method and a device of barreled drinking water; full physical disinfection technology without any chemical sanitizing agent and any chemical preservative is utilized; a disinfection system consists of a forward series connection type ultrafiltration membrane filter system in a water production factory and backward series connection type ultraviolet radiation disinfection systems respectively set at all user ends; a disinfection safety automatic detection control device is also configured; more than 99.99 percent of viruses in the original water and more than 99.9 percent of other pathogenic microbes can be killed; more than 99.9 percent of generated reproduction bacteria caused by barrel wall stemming and water gas mixing during storage and transportation after the barreled drinking water is packed and during the operation can be killed; meanwhile, any disinfection by-product can not be generated; the drinking water of good quality and with remained quantity property can be obtained; the method can practically solve the problems that the disinfection by-product is generated in the current chemical technology and the current physical disinfection technology is short of disinfection durative and safety; the view having been generally recognized by the water production industry for a long time is changed that the physical disinfection technology cannot be used separately and can be combined with the chemical disinfection method; thus, the method of the invention has strong practicability.

Description

technical field [0001] The invention relates to the technical field of domestic drinking water treatment, in particular to a composite and separate physical disinfection method and device for bottled drinking water. Background technique [0002] The quality of drinking water is closely related to human health. For a long time, drinking water for urban residents was mainly supplied by water companies. But, when surface water (river, river, lake water) is seriously polluted, the quality of tap water prepared with surface water as water source will be affected. As a result, "bottled drinking water" that selects clean water sources or groundwater sources in different places as raw water, supplies them in the form of "barrels", and is characterized by "use in different places" has come out. In recent years, the market for bottled drinking water has developed rapidly, and it has become a mainstream variety of drinking water supply for residents in many regions and cities in my c...
