Embodiment 1

[0013] Preparation of hard water softener: Take 1.5g of diatomite, 0.2g of sodium carbonate, 0.1g of sodium hydroxide, 1g of activated carbon, then add 7.2g of deionized water, mix well, dry and shape, and obtain purification softener 1;

[0014] Preparation of filter column: first put a layer of filter paper in the adsorption column, then add a layer of 5mm filter paper pulp layer, then put 2g of diatomaceous earth, 5g of purification softener 1, and 2g of activated carbon in turn, and then add a layer of 5mm of filter paper pulp, then put a layer of filter paper, and finally drain to obtain the filter column 1.

Embodiment 2

[0016] Preparation of hard water softener: Take 1.5g of diatomaceous earth, 0.5g of sodium carbonate, 0.2g of sodium hydroxide, 2g of activated carbon, then add 5.8g of deionized water, mix well, dry and shape, and obtain purification softener 2;

[0017] Preparation of filter column: first put a layer of filter paper in the adsorption column, then add a layer of 5mm filter paper slurry layer, then put 1g of diatomaceous earth, 8g of purification softener 2, and 1g of activated carbon in turn, and then add a layer of 5mm of filter paper pulp, then put a layer of filter paper, and finally drain to obtain the filter column 2.

Embodiment 3

[0019] Preparation of hard water softener: Take 2.5g of diatomaceous earth, 0.2g of sodium carbonate, 0.1g of sodium hydroxide, 1g of activated carbon, then add 6.2g of deionized water, mix well, dry and shape, and obtain purification softener 3;

Abstract

The invention specifically relates to a hard water softening agent and its preparation method and application, belonging to the field of tap water treatment. The hard water softening agent comprises the following components by weight: 15-25% of diatomite, 1-5% of sodium carbonate, 1-2% of sodium hydroxide and 10-20% of activated carbon, with the balance being deionized water. The hard water softening agent provided by the invention purifies and softens tap water in one step and is convenient and quick; through addition of the activated carbon, residual chlorine in tap water can be effectively filtered out; in particular, the diatomite is added into the purifying softening agent, so the softening agent is allowed to have good physical adsorption properties due to the great specific surface of the diatomite; after calcium and magnesium ions in tap water form precipitates with sodium carbonate and sodium hydroxide in the purifying softening agent, the precipitates can be adsorbed by the diatomite; and the design of a filter column makes the calcium and magnesium ions in tap water to be fully precipitated, so residual chlorine can be effectively filtered out.

Description

technical field [0001] The invention belongs to the field of tap water treatment, and in particular relates to a hard water softener and a preparation method and application thereof. Background technique [0002] Hard water refers to water containing a large amount of calcium ions and magnesium ions, which brings many hazards to life and production. For example, scale is generated when hard water is heated, and scum produced by contact with soap affects the cleaning effect. Drinking water with high hardness affects health and brings losses to industrial production. When hard water passes through the pipeline, scale tends to stick to the pipe wall for a long time. It is easy to damage the equipment. The content of calcium and magnesium ions in tap water is generally high, and the residual chlorine in tap water is also very harmful to human health. At present, hard water softening methods include ion exchange method, membrane separation method, dosing method, etc., but some ...
