Embodiment 1
[0031] Sodium carbonate, calcium carbonate, clay and water are mixed in a weight ratio of 10:20:70:100, stirred evenly, and poured into a mold. Put the mold into an oven and dry it at 100°C to obtain sodium carbonate sustained-release granules. The granules are embedded in a polyvinylidene fluoride microporous membrane with a pore size of 1 micron, and then the polyvinylidene fluoride microporous membrane embedded with sodium carbonate sustained-release particles is filled into a cylindrical plastic shell to form a Slow release softening filter.
[0032] Calcium hardness is 300ppm (as CaCO 3 meter), pH = 7 water through such as figure 1 device shown. figure 1 Among them, a device for partially softening drinking water, including a slow-release softening filter element 1 and an ultrafiltration device 2.
[0033] Then detect the pH value of water, turbidity and calcium hardness, obtain: pH=7.6, turbidity3 count).
Embodiment 2
[0035] Sodium carbonate, calcium carbonate, clay and water are mixed in a weight ratio of 20:20:60:100, stirred evenly, and poured into a mold. Put the mold into an oven and dry it at 100°C to obtain sodium carbonate sustained-release granules. The granules are embedded in a polyvinylidene fluoride microporous membrane with a pore size of 2 to 3 microns, and then the polyvinylidene fluoride microporous membrane embedded with sodium carbonate sustained-release particles is filled into a cylindrical plastic shell, Made into a slow-release softening filter.
[0036] Calcium hardness is 400ppm (as CaCO 3 meter), pH = 7 water through such as figure 1 device shown. figure 1 Among them, a device for partially softening drinking water, including a slow-release softening filter element 1 and an ultrafiltration device 2.
[0037] Then detect the pH value of water, turbidity and calcium hardness, obtain: pH=8.2, turbidity3 count).
[0038] The results show that the calcium hardness ...

Abstract
The invention discloses a drinking water softener and a softening method and softening equipment thereof. The drinking water softener is a sustained-release softener which is preferably soluble carbonate sustained-release agent and comprises the following components in part by weight: 1 to 3 parts of soluble carbonate, 2 to 5 parts of calcium carbonate and 2 to 7 parts of clay. A preparation method comprises the following steps of: mixing the soluble carbonate, the calcium carbonate, the clay and water and stirring uniformly; pouring the mixture into a mould; and drying and forming. In the method, the sustained-release agent is prepared from the soluble carbonate and put in a microporous membrane; when hard water flows through a sustained-release softening filter element, the soluble carbonate is slowly dissolved and released through the microporous membrane to further react with calcium ions in the water to produce insoluble calcium carbonate; and finally the insoluble calcium carbonate is filtered by an ultrafilter so as to reduce the calcium ion content of the hard water and fulfill the aim of partial softening. The drinking water softening method has the advantages of small investment, safety and convenient use and is particularly applicable to the softening of household drinking water.
Description
technical field [0001] The invention relates to a drinking water softening technology. Background technique [0002] The so-called hard water is water that contains a large amount of calcium and magnesium salt ions. When this kind of water is used at home, it cannot make soap produce foam, and it will also deposit a layer of scale on the washed clothes; when the water is boiled, a layer of hard white scale will gradually form on the bottom of the pot and the bottom of the thermos. This is very annoying. [0003] There are many ways to soften hard water and avoid scale deposits. The commonly used methods are: [0004] 1) Ion exchange method: use specific cation exchange resin to replace calcium and magnesium ions in water with sodium ions. This method is currently the most commonly used standard method, as described in patents CN02142568X, CN2084049, CN2183363, and CN2509174. Its main advantages are: the effect is stable and accurate, and the process is mature. Can reduc...
