Embodiment Construction

[0026] Reference figure 1 . The weakly alkaline salt-free water produced by the mesh electrode guide type industrial electrodialyzer and the ozone produced by the ozone generator enter the Venturi mixer together, and then enter the ozone absorption tower for further mixing through the mixing jet, and part of it flows back to the Venturi mixer , It is again mixed with the ozone entering the Venturi mixer, and then injected into the ozone absorption tower to mix again, through the reflux type ozone sterilization method, effectively kill the microorganisms in the water. The ozone-sterilized water and bubbles enter the gas-water separation tower for necessary water-gas separation. When the bubbles pass through the water cap in the gas-water separation tower, the bubbles burst, and the separated gas enters the respirator and is catalytically decomposed by activated carbon. Discharge; the separated water enters the primary ultrafilter to filter out the microbial corpses and other suspe...

Abstract

The present invention relates to post treating method and device for producing weak alkaline high purity drinking water. Weak alkaline no-salt water and ozone gas are made to enter first to the Venturi mixer and ozone absorption tower for ozone sterilization and then to a gas-water separating tower to separate out and exhaust ozone containing gas; and the separated water is filtered in the first stage filter to eliminate microbe and suspended matter, active carbon tank to eliminate organic matter and bad smell, and the second stage filter to eliminate residue and obtain weak alkaline high purity drinking water. The whole process is completed inside one closed system with balanced pressure to eliminate foreign matters effectively.

Description

Technical field [0001] The invention relates to a method and equipment for producing high-purity drinking water, in particular to a post-treatment method and equipment for producing weakly alkaline high-purity drinking water. Background technique [0002] The weakly alkaline salt-free water produced by the mesh electrode guide type industrial electrodialysis device, except for a very small amount of sodium hydroxide, has basically no inorganic substances, but contains weaker polarities such as chloroform and tetrachloride Organic matter such as carbon and microorganisms that are not affected by electric field force. The PH value of weakly alkaline salt-free salt water is 7.1 to 7.6, which is very conducive to the survival and reproduction of microorganisms. If this is not effectively controlled in time, the content of bacteria and viruses will show up. The upward trend has caused the consumption of potassium permanganate and the two physical and chemical indicators of nitrite to ...
