Abstract
The invention belongs to water treatment field, and in particular to a kind of water softening agent and its preparation method and application.Described water softening agent includes following weight percentage component：Diatomite 15 25%；Sodium carbonate 1 5%；Sodium hydroxide 1 2%；Activated carbon 10 20%；Deionized water surplus.The present invention completes the purification of running water and one step of softening, convenient and swift.The addition of activated carbon can effectively filter out the chlorine residue in running water, diatomite has been especially added with purification softening agent, abundant ratio surface makes it have good physical absorption performance, and the calcium ions and magnesium ions in running water can be very good by kieselguhr adsorption after forming precipitation with the sodium carbonate in purification softening agent, sodium hydroxide.The design of Filter column make it that the calcium ions and magnesium ions in running water are fully precipitated, and effectively filters out chlorine residue.
Description
Technical field
The invention belongs to water treatment field, and in particular to a kind of water softening agent and its preparation method and application.
Background technology
Hard water refers to the water containing a large amount of calcium ions and magnesium ion, and many harm are brought in being produced to life.Such as hard water adds
Incrustation scale is produced when hot, is contacted with soap and produces scum silica frost influence cleaning performance, drinking the larger water of hardness influences health, and
Loss is brought to industrial production, when hard water passes through pipeline, incrustation scale is easily sticked to the time on tube wall and has grown and be easily damaged equipment.Originally
Calcium ions and magnesium ions content in water is generally higher, while the chlorine residue in running water also has very major injury to human body health.At present, firmly
Water softening method has ion-exchange, membrane separation process, method for dosing medicine etc., but the method cost of investment that has is high, the method that has is dangerous.
The content of the invention
The shortcomings that it is an object of the invention to overcome in the prior art, there is provided a kind of water softening agent and preparation method thereof and
Using.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of water softening agent, including following weight percentage component：
Present invention additionally comprises a kind of preparation method of described water softening agent, by described diatomite, sodium carbonate, hydrogen-oxygen
Change sodium and activated carbon stir after being dissolved in water, then drying and moulding.
Present invention additionally comprises a kind of application of described water softening agent, and one layer of filter paper is first put into glass adsorption column,
One layer of 5mm filter paper pulp layer is added, is then sequentially placed into the work of 1-5g diatomite, water softening agent, 1-2g described in 5-10g
Property charcoal, then above add one layer of 5mm filter paper pulp layer, then put last layer filter paper, finally drain.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention completes the purification of running water and one step of softening, convenient and swift.The addition of activated carbon can be filtered out effectively
Chlorine residue in running water, purify and diatomite has been especially added with softening agent, abundant ratio surface makes it have good physics and inhaled
Attached performance, the calcium ions and magnesium ions in running water can be very good after forming precipitation with the sodium carbonate in purification softening agent, sodium hydroxide
By kieselguhr adsorption.The design of Filter column make it that the calcium ions and magnesium ions in running water are fully precipitated, and effectively filters out chlorine residue.
