Problems solved by technology

However, no oxidizing agent is added in the production process of the current water purifier, and ferrous iron cannot be converted into ferric iron. In the production process, inorganic polymers are formed, and other additives need to be added to form flocs during use. Fast water purification effect, and the solid-liquid separation effect is poor when used, and the water insoluble content is too high, which affects the water purification effect

Abstract

The invention discloses an aluminum ferric sulfate water purifier and a preparation method thereof. The aluminum ferric sulfate water purifier is prepared from the following components in parts by weight: 200-240 parts of hydrochloric acid with concentration of 18 percent, 340-380 parts of sulfuric acid with concentration of 93 percent, 30-50 parts of phosphoric acid with concentration of 35 percent, 10-20 parts of aluminum powder, 14-18 parts of iron powder, 50-60 parts of calcium powder, 140-160 parts of calcium aluminate powder containing 53 percent by weight of calcium aluminate, 2-4 parts of hydrogen peroxide and 240-260 parts of water. The aluminum ferric sulfate water purifier has certain killing power for some bacteria and viruses adverse to growth of biochemical bacteria in sewage. When the biochemical bacteria are in a sleep state, the biochemical bacteria can quickly revive by using the aluminum ferric sulfate water purifier; and the aluminum ferric sulfate water purifier has a stronger sterilization effect, so that the biochemical efficiency can be effectively increased and the water quality is changed in a short time.

Description

technical field [0001] The invention belongs to the field of water purifying agents, in particular to an aluminum iron sulfate water purifying agent, and also relates to a preparation method of the water purifying agent. Background technique [0002] Aluminum and iron polymer inorganic polymer water purifiers are a new type of chemical industry researched and developed from the 1970s to the 1990s, which has played a great role in improving people's quality of life and improving the environment. There are many types of water purifiers, and the production processes are different. However, no oxidizing agent is added in the production process of the current water purifier, and ferrous iron cannot be converted into ferric iron. In the production process, inorganic polymers are formed, and other additives need to be added to form flocs during use. Fast water purification effect, and the solid-liquid separation effect is poor when used, and the water insoluble content is too high...
