Problems solved by technology

However, because the powdered water purifier is easy to absorb moisture and deliquescence before use, the active ingredients of the water purifier in the woven bag will be lost, and the shelf life of the solid water purifier will be shortened, so the storage time of the powdered water purifier is generally short , therefore, it is necessary to propose a new scheme to solve the above problems

Embodiment 1

[0047] Embodiment 1: refer to figure 1 , a moisture-proof water purifying agent, comprising a first modified water purifying agent, the first modified water purifying agent comprises a water purifying agent inner core 1 and a moisture-proof film 2 wrapped on the outer wall of the water purifying agent inner core 1 . Wherein, the inner core 1 of the water purifying agent in this embodiment is powdery polyaluminum chloride, and the particle diameter of the inner core 1 of the water purifying agent is less than 1 mm. The first modified water purifying agent is prepared through the following steps:

[0048] Step 1: Completely dissolve the inner core of the water purifying agent and water in water at a ratio of 2g / L to obtain the first mixed solution.

[0049] Step 2: Add sodium alginate to the first mixed solution, the weight ratio of sodium alginate to the inner core of the water purifier is 1:2, stir, and dissolve the sodium alginate to obtain the second mixed solution;

[005...

Embodiment 2

[0054] Embodiment 2: A moisture-proof water purifying agent, the difference from Embodiment 1 is that the inner core of the water purifying agent in this embodiment is powdered polyaluminum ferric chloride.

Embodiment 3

[0055] Embodiment 3: A moisture-proof water purifying agent, the difference from Embodiment 1 is that the inner core of the water purifying agent in this embodiment is powdered basic aluminum chloride.

Abstract

The invention discloses a moisture-proof water purifying agent as well as a preparation method and a use method thereof, and relates to the field of water treatment. According to the technical scheme,the moisture-proof water purifying agent comprises a first modified water purifying agent, the first modified water purifying agent comprises a water purifying agent inner core and a damp-proof filmwrapping the outer wall of the water purifying agent inner core, and the moisture-proof water purifying agent has the advantages of being not prone to moisture absorption and chain deliquescence, andcapable of prolonging the shelf life of the powdery water purifying agent.

Description

technical field [0001] The invention relates to the field of water treatment, more specifically, it relates to a moisture-proof water purifying agent and its preparation method and application method. Background technique [0002] Water purifiers are agents that can react with other impurities in water when put into water, mainly for the purpose of water purification. The existing commonly used water purifiers include polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, polyacrylamide, ferrous sulfate, aluminum sulfate, polyferric sulfate, etc. On this basis, people have also invented more efficient water purifiers. [0003] Disclose a kind of production technology of composite water purifying agent polyaluminum ferric sulfate in the Chinese invention patent that notification number is CN1160253C, adopt the ferric oxide waste slag after sulfuric acid factory produces sulfuric acid as raw material, according to stoichiometric, water, slag, sulfuric a...
