Problems solved by technology

The disinfection process mainly increases the input of disinfectants or uses ultraviolet light or ozone to kill and sterilize. Although this method can inhibit the growth of viruses and bacteria, it also increases disinfection by-products, which is extremely harmful to the human body.
[0032] In addition, the reverse osmosis method is mainly used in the water supply mode of water supply plants and households, although this can make the water supply clean, but the waste of water resources is too large (using the reverse osmosis method to treat one ton of water requires 4-6 tons of raw water )
[0033] In addition, in order to drink safe and healthy drinking water, many people began to choose to buy bottled water or bottled water, or home-installed water purifiers to ensure water quality safety, but drinking such water for a long time or in large quantities cannot obtain the human body from the water. Trace elements also cause a large amount of white garbage, which is extremely harmful to environmental protection

Abstract

The invention relates to high florine water treatment equipment, and provides a defluorination magnetic attraction material and water treatment equipment comprising the same. The magnetic attraction material is prepared from ferric salt, nickel salt and manganese salt through a hydrothermal reaction under the alkaline condition, and is obtained through filtering, drying and high-temperature calcination. The fluorine removal agent is large in attraction capacity, and can effectively remove fluorions in water after being treated by the high florine water treatment equipment, can be repeatedly used after being regenerated, is good in regeneration performance and still has the good attraction effect after ternary cycle use.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to the field of water treatment equipment for high fluoride content in drinking water. Background technique [0002] Fluorine is one of the trace chemical elements widely distributed in the natural environment and closely related to human health. Fluorine is a non-metallic chemical element with very active chemical properties. Every tissue of the human body contains a trace amount of fluorine, 80-90% of which is concentrated in the teeth and bones of the human body. It is an important element for preventing dental caries and promoting calcium metabolism in bones. [0003] Fluorine in the human body comes directly from drinking water, food and air, and about two-thirds of it comes from drinking water. Long-term drinking of high-fluorine water (>1.0mg / L) by humans can cause calcium and phosphorus metabolism disorders in the human body, resulting in calcium deficiency in the human body ...
