Drinking water purifying agent and preparation method thereof

Abstract

The invention relates to a drinking water purifying agent and a preparation method thereof. The drinking water purifying agent comprises the following components in parts by weight: 15-30 parts of calcite, 10-30 parts of tungsten oxide, 3-10 parts of magnesium aluminum oxide, 15-40 parts of bentonite, 10-30 parts of calcium phosphate, percarbonic acid 5-7 parts of sodium, 5-15 parts of iron sulfate, and 5-15 parts of activated carbon. The applied water purifier provided by this application has high adsorption, can effectively absorb lake water, river water or well water, etc., which can be used as impurities in drinking water sources, is non-toxic and harmless, and the purified water quality can reach drinking standards; and The processing method is simple, and the treatment process will not cause secondary pollution to the water quality; the treated drinking water meets the national secondary drinking water purification standard; compared with the biochemical filtration method, the purification efficiency is high, the cost is low, and it will not Substances harmful to the human body remain in the water.

Description

technical field [0001] The invention belongs to the technical field of new energy, environmental protection and energy saving, and in particular relates to a drinking water purifying agent and a preparation method thereof. Background technique [0002] With the rapid development of economy and society, the water pollution caused by industry, agriculture and residents' life is becoming more and more serious. The pollution of drinking water and the shortage of purified drinking water supply are also more and more worrying. Drinking water is polluted by harmful inorganic ions and heavy metals, especially arsenic and fluoride. Arsenic poisoning can cause lung cancer, kidney cancer, bladder cancer, skin cancer and other skin diseases, while fluorosis can cause dental fluorosis or skeletal fluorosis. Therefore, drinking water purification has become one of the hottest topics nowadays. The traditional technology is to use magnesium oxide to remove arsenic and fluoride in water, b...

AI Technical Summary

Problems solved by technology

The traditional technology is to use magnesium oxide to remove arsenic and fluoride in water, but when magnesium oxide is in contact with water, it will form a paste-like or slurry-like magnesium hydroxide, which will reduce the flow rate of water or even stop the flow of water, to a certain extent Become a bottleneck in the development of drinking water treatment technology

There are also purification technologies such as column purification, reverse osmosis, and hydroxide precipitation, but they all have their own shortcomings or shortcomings. Either the effect of arsenic and fluorine removal is not ideal, or the cost is high, or it has certain pollution or subsequent use is difficult. Therefore, There is a need to find a scavenger that can effectively remove arsenic and fluoride ions from water without slowing down the water flow rate
