Drinking water treatment apparatus

Abstract

The invention relates to a water treatment apparatus. The drinking water treatment apparatus comprises an ultraviolet sterilizer, an iron and manganese removal filtering apparatus, a multi-hydrogen generator, an active carbon filter, a pulse booster pump, a water purification box, a primary filtering apparatus and a secondary nanofiltration apparatus. By virtue of the cooperative use of the apparatuses, the produced drinking water is nontoxic, harmless, colorless, free from impurities, pollution-free and odorless, the water hardness and the content of calcium carbonate are appropriate, and content of calcium carbonate is about 190ppm and close to that of the natural water.

Description

technical field [0001] The invention relates to the field of drinking water treatment, in particular to a drinking water treatment device. Background technique [0002] At present, the preparation process of tap water in cities is made by using groundwater, river water and other water sources, after precipitation, disinfection with chlorine gas, filtration and other processes, which is the water flowing out of our daily tap water pipes. Chlorine gas is used, and when chlorine gas dissolves in water, it will react with water to produce hydrochloric acid and hypochlorous acid. Although hypochlorous acid has a good bactericidal effect, it is equally harmful to the human body due to its strong oxidizing properties. [0003] In addition, due to the illegal discharge of waste gas and waste water by many industrial enterprises in recent years, the quality of breathing and drinking water of residents has been seriously affected. After the smog settles, a large part of it dissolves ...

AI Technical Summary

Problems solved by technology

In this process, many harmful substances dissolved in water can actually be decomposed, evaporated or precipitated. For example, hypochlorous acid will decompose into chlorine gas and water after being heated, the solubility of sulfur dioxide solution will be greatly reduced after being heated, and many heavy metal ions will form after heating. Alkaline precipitation, these precipitates will also cause some adverse effects on human health

[0005] Patent CN207031200U discloses a drinking water treatment device, which adopts flocculation equipment, sedimentation equipment, ozone biological activated carbon equipment, membrane treatment equipment and chlorine disinfection equipment. Although water pollution can be treated, chlorine gas is used in the preparation process, and chlorine gas After dissolving in water, it will react with water to produce hydrochloric acid and hypochlorous acid. Although hypochlorous acid has a good bactericidal effect, it is also harmful to the human body due to its strong oxidizing properties.

Patent CN108117191A is a membrane method drinking water treatment system and method, which adopts sedimentation tank, self-cleaning filter device, ultrafiltration device, low-pressure reverse osmosis device, and uses membrane method treatment and low-pressure reverse osmosis device, but its disadvantages are: some micro Incomplete filtration of bacteria and harmful bacteria
