Process for preparing Gua-water in Dabie mountain area

Abstract

The invention relates to a process for preparing the Gua-water in the Dabie mountain area, which comprises the steps of (1) selecting the mountain spring water in the Dabie mountain area as the raw water and filtering the raw water by a sand filter; (2) filtering the water treated in the step (1) by the activated carbon, wherein the particle size of the activated carbon is 0.42-0.65 mm during the filtering process; (3) filtering the water treated in the step (2) by a manganese sand filter; (4) sterilizing the water by medium-pressure ultraviolet rays; (5) treating the water by adopting the UH reverse osmosis technique; (6) sterilizing the water by means of ozone and fully mixing the ozone with the water during the sterilizing process, wherein the ozone content in the water reaches 0.12 mg / L; (7) completing the aseptic filling process of the treated water. According to the invention, the water prepared by the above process is free of pollution, pathogens, heavy metals and harmful chemical substances. Meanwhile, the water contains minerals and trace elements necessary for human bodies. Moreover, the water, free from degrading, is in the form of alkalescent small molecular group water and is strong in activity. In addition, the water is rich in beneficial minerals, such as strontium, zinc, selenium, metasilicic acid and the like.

Description

technical field [0001] The invention belongs to the field of drinking water, and in particular relates to a production process of drinking water in the Dabie Mountains. Background technique [0002] Pure water is made from rivers, lakes, tap water, etc., and is made by distillation, electrodialysis, ion exchange, reverse osmosis and other treatment processes. It removes various elements in the water to the maximum extent and only retains water molecules. While removing harmful substances, beneficial substances are also removed; mineral water retains some substances and trace elements in the water to a certain extent, and the content of one or more minerals reaches the national standard. There are many drinking water beverages at home and abroad, such as Wahaha drinking pure water, Nongfu Spring drinking natural water, Evian natural mineral water and so on. According to the data, most domestic drinking water production sterilization processes use ozone or ultraviolet lamps f...

AI Technical Summary

Problems solved by technology

According to the data, most domestic drinking water production sterilization processes use ozone or ultraviolet lamps for sterilization treatment. Although the one-step sterilization method is simple, the sterilization effect is poor. At the same time, in the existing water filtration steps, quartz is mostly used. Sand and activated carbon are treated by layered filtration, and the filtration and adsorption effects are not good during treatment. In order to improve the cleaning effect, it is often necessary to increase the thickness of the filter medium
