Efficient treatment process for natural mineral water

Abstract

The invention discloses an efficient treatment process for natural mineral water. The efficient treatment process specifically comprises seven steps of mineral water collection, rough filtration, finefiltration, ultrafiltration, sterilization and disinfection and filling. Four filtering materials of medical stone granules, manganese sand, vesuvianite and cocoanut active charcoal are used in the step of rough filtration, and thus heavy metals, colloid and organic matter molecules in mineral water are adsorbed to the maximum extent; a graphene technique is used in the step of fine filtration, various pollutants in the mineral water are removed, and various pathogenic bacteria in the mineral water are killed or blocked; a reverse osmosis technique is used in the step of ultrafiltration, so that substances such as dissolved salts, colloid, microorganisms and organic matters in the mineral water are further effectively removed; finally with the combination of ozone and a disinfectant, themineral water is sterilized and disinfected, various pathogenic bacteria in the mineral water are killed, human health is prevented from being affected by bacteria in the mineral water, and the efficient treatment process is high in treatment efficiency, good in filtering effect and good in water quality purification effect when being adopted for mineral water treatment. Therefore, the efficient treatment process has very high social benefits and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of drinking water preparation, and in particular relates to a high-efficiency treatment process of natural mineral water. Background technique [0002] Natural mineral water is unpolluted underground mineral water that gushes out naturally from deep underground or is artificially exposed. Mineral water is formed deep in the formation, which contains a certain amount of mineral salts, trace elements or carbon dioxide gas. As drinking water, the nine limit indicators of mineral water stipulated in the national standard include lithium, strontium, zinc, selenium, bromide, and iodide , metasilicate, free carbon dioxide and total dissolved solids, one or more of which must meet the requirements of the limit index, and the required content is (unit: mg / L): lithium, strontium and zinc are all ≥ 0.2, and iodine Compound ≥ 0.2, selenium ≥ 0.01, bromide ≥ 1.0, metasilicate ≥ 25, free carbon dioxide ≥ 250, total disso...

Problems solved by technology

Since natural mineral water is often affected by the external environment, it contains a large amount of organic matter, and the iron ions in the water usually exceed the national standard, so it is not suitable for direct drinking. From the perspective of people's health, after collecting natural mineral water, it is necessary to clean it. Purif
