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.

Abstract

The invention provides compound effervescent tablets for water purification and disinfection and a preparation method thereof. The compound effervescent tablets for water purification and disinfection comprise the components of a disinfector, food level polyaluminium chloride, food level chitosan and auxiliary materials of effervescent tablets, wherein the disinfector is stable chlorine dioxide powder or potassium monopersulfate disinfecting powder, the content of the food level polyaluminium chloride is 10-15mg, the content of the food level chitosan is 1-2mg and the balance is the auxiliary materials of effervescent tablets. The purifying agent has the advantages of simple preparation process, low cost and good purifying effect, and is suitable for disinfection for military personnel, field operation personnel, tourists and residents in regions without tap water as well as for disinfection of industrial drinking water.

Description

technical field [0001] The invention relates to a composite water purification and disinfection effervescent tablet and a preparation method thereof, belonging to the technical field of water purification tablet processing. 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; s...
