Description

technical field [0001] The invention relates to the field of effervescent tablets, in particular to a water-purifying and disinfecting effervescent tablet and a preparation method thereof. Background technique [0002] Solving the problem of drinking water in the open air is a difficult problem, because the water quality is complex and difficult to handle. When troops are performing field missions, although there is a large amount of fresh water in rivers and lakes, they cannot be directly drunk due to the large number of microorganisms and pathogenic bacteria in the water. During flood relief and disaster relief, the army and the affected people could not drink clean water due to the pollution of the water body. Some people developed intestinal infectious diseases such as dysentery due to drinking contaminated water. Therefore, there are three main aspects in processing natural water into potable water in the wild: first, disinfection; second, precipitation and removal of...

Problems solved by technology

[0003] However, the water purification tablets currently on the market are only for the disinfection of water sources, and do not pay attention to the treatment of a large number of solid impurities, because a large number of solid impurities are small and suspended in the water, and cannot be removed by standing for a long time or simple filtration, resulting in purified water. There are too many suspended solids in the water after the disinfection treatment of the tablet, which has a bad smell and is not suitable for drinking at all.
