Description

Environment-friendly ocher mortar and its manufacturing method {Yellow soil mortar composition and the said manufacturing process}

The present invention relates to an environmentally friendly loess mortar. More specifically, the present invention, after adding ocher to water, stirring and settling, and then, the supernatant is forced to a two-step filtration system by using a motor pump to purify and sterilize the mineral. The present invention relates to a loess mortar using a loess residue, which is a by-product produced in the process of preparing a large amount of alkaline purified water, and a method of manufacturing the same.

Conventionally, a number of methods for obtaining purified water by purifying contaminated ground water or water tap have been commonly known. Eating purified water is the most critical and urgent situation in the water and soil environment in which rivers are contaminated and groundwater is recently contaminated. Activated carbon filter systems are known for supplying purified water to raw water, such as tap water, surface water, groundwater, and wastewater. Such a system has been utilized in a beverage production apparatus and wastewater treatment apparatus because it can remove the taste, smell, residual chlorine or organic matter of raw water to be treated by using strong adsorption power of active carbon.

In addition, the mixed bed-deionizer system is a device that mixes and fills a cation exchange resin and an anion exchange resin in a sealed container, and passes only raw water to remove various positive and negative ions from raw water to produce pure water only. In addition, when the performance of the ion resin is degraded, it can be regenerated using hydrochloric acid and NaOH and used continuously. Such systems have been used for the production of electronic industrial water in the fine chemicals and semiconductor fields.

Reverse osmosis system, on the other hand, is a very recently introduced filtration method that pressurizes raw water to separate and concentrate solutes without phase change, filtering only pure water (H ₂ O), and generating molecules of ions or other substances. It has been widely applied to beverages, seawater desalination systems, electronics and semiconductor equipment industries and other wastewater treatment fields.

As described above, various filtration systems have been researched and developed to remove and purify microorganisms, organic matter and other impurities from raw or waste water, including contaminated tap water, surface water, ground water, industrial water, and wastewater. Until now, by adding ocher to groundwater, tap water, and surface water, a large amount of minerals required for human body are eluted, and a method of preparing the same as alkaline purified water has not been known at all. Moreover, ocher mortar prepared by using ocher residue which is a by-product obtained in the preparation of the novel alkaline purified water has not been known at all.

The present invention has been made in view of the above-mentioned point, and an object of the present invention is to provide alkaline purified water containing a large amount of minerals using relatively little pollution. Another object of the present invention is to provide a method for producing purified water in which a large amount of minerals are alkaline and remove microorganisms such as bacteria, organic substances and other impurities. Still another object of the present invention is to provide an ocher mortar from which harmful bacteria are removed using an ocher residue containing a large amount of the mineral.

In particular, the ocher mortar of the present invention, when used for plastering concrete bricks and conventional soil bricks, not only emits far-infrared rays through the walls, but also has excellent deodorizing and humidity control functions to provide a human-friendly and environmentally friendly building culture. Excellent effect.

The above object of the present invention is to add a yellow soil to the raw water of relatively less pollution, such as Paldang water source, and stirred using a stirrer and then only the supernatant using a motor pump, a two-stage filtration system (Two -step filtration system), filtered by force, sterilized by UV sterilizer (UV sterilizer) to obtain a strong alkaline purified water containing minerals, and by steam heating the by-product residue ocher residues and filtered by human-friendly eco-type ocher mortar Achieved by providing

Hereinafter, the specific configuration and operation of the present invention will be described in detail with reference to preferred drawings and process-specific embodiments, but the scope of the present invention is not limited only to these embodiments, and those skilled in the art can add some configurations within the scope of the above embodiments. Or by changing the design can be carried out by deletion, of course, in this case violates the rights of the present invention.

Figure 1 is a schematic process diagram showing a preferred embodiment of the present invention loess mortar.

2 is a diagram showing a preferred embodiment of a two-step filtration system of the present invention for producing alkaline purified water.

Preferred embodiments of the invention are shown in FIGS. 1 and 2. According to these figures, the present invention comprises the steps of adding ocher to raw water; Eluting the minerals by stirring the raw material mixed with ocher to be the mineral source in a stirrer; A precipitation step for 30 to 60 minutes; Forcing the supernatant, which is the raw material water of the present invention, in which the mineral is eluted, to the two-stage filtration system by a motor pump and filtering the same; Sterilizing the filtered purified water through a UV sterilizer and steam heating the ocher residue, which is a by-product of the purified water production process; Mixing the charcoal powder in a filtrate of 0.1 mm or less after filtration; It is characterized by consisting of a step of drying.

In the present invention, the raw water may be any of tap water, ground water, and surface water, but raw water, for example, Paldang water source water, is collected from a relatively low pollution source. The content of minerals liberated from ocher under the same conditions may vary when the ocher is mixed and stirred according to the type of raw water. On the other hand, in the case of ocher added to the same raw water (原 水) there is a big difference also depending on the source, namely the mountain and the type of loess. As the type of ocher to be added, any one of Kaolirite, illite, Montmollilonite, zeolite and pearlite can be selected and added as necessary.

Conveyor belt systems are most preferred as a device for introducing loess, which is a mineral source, into raw water. And the stirrer is the most preferred rotary type, but any industrial stirrer may be used. The stirring speed required to induce the mineral supply in the rotary stirrer is not critical but is satisfactory at around 50 to 150 rpm.

If necessary, a centrifuge may be used instead of the stirrer.

On the other hand, the level of ocher added to the raw water is preferably 1 to 50% by weight, more preferably 20 to 30% by weight. In order to increase the level of mineral supply from loess, loess is used without heating by heating at 121 ° C for 15 minutes by autoclave. In addition, a means for increasing the amount of mineral leaching from unburned raw yellow soil can be employed.

The time required for ocher settling after stirring is related to the type and amount of ocher and whether it is burned or not, but it is generally satisfactory if it is 30 to 60 minutes. After stirring, ocher residues (Residues) can be provided to the ocher pack for skin massage by adding herbal medicines as needed.

On the other hand, the supernatant separated on the yellow soil layer (Supernatant) is filtered through a two-step filtration system (Two-step filtration system) by a motor pump (see Fig. 2).

The first step is to pass a pressure filter system to remove rust, dust, particles and microbes from the supernatant from which minerals are eluted from the loess ( I stage).

The device is to make a collecting device in the lower part of the sealed container and fill Silica sand and Silica gravel as a support material thereon to remove turbidity as raw water passes through the filter medium to reduce turbidity. The filtration apparatus may be reused by releasing foreign substances to the outside through a backwashing process, and is configured in a vertical type so that the filtration area is large, thus obtaining uniform water quality.

The second step is an ultra-filtration system (ultra-filtration system) heavy metals, such as dust present in the fluid passed through the first stage, heavy metals larger than water molecules, Virus, chlorine, trihalo methane, H ₂ S, Removes odors and other pollutants and suspended solids (Step II).

In general, ultra-filtration involves placing a liquid in the presence of a semi-permeable membrane so that two kinds (some of the passages) pass through the membrane and the other (residues) in the liquid fluid. to be. Therefore, in the ultrafiltration system of the present invention, the base liquid passes through the filtering network. At this time, the semi-permeable membrane is made in a tubular shape, the base liquid passes through the tube, and the permeate passes through the tube. On the other hand, the semi-permeable membrane may be formed of a hollow fiber membrane, in which case a bundle of hollow fiber membranes may be embedded in a tubular housing, and the base liquid penetrates the cores of the hollow fiber membrane.

The material of the semi-permeable membrane of the base liquid used in the embodiment of the present invention uses a metal inorganic film composed of stainless titanium, which is a stainless support (sintered thickness 0.8) of a uniform stainless powder having a particle diameter of 30 to 40 µm. Module consisting of a micro filer film having a thickness of 30 to 50 μm and a pore diameter of 0.1 μm in a titanium active layer obtained by sintering the same amount of titanium (TiO ₂ ) powder (particle diameter of 0.3 to 0.5 μm) on a surface of ˜1.5 mm and a pore diameter of 1 μm. This is suitable.

The preferred two-stage filtration system of the present invention is indicated by the steps I, II in FIG.

Purified water passed through the second stage ultrafiltration system is finally sterilized by passing through a UV sterilizer. Ultraviolet rays, which are shortwaves, contact all microbial cells at a wavelength of 254 mm, inactivating DNA in the nucleus and destroying them by applying a physical shock.

Purified water thus purified was an alkaline beverage in which a large amount of minerals were eluted from the loess, and at the same time, bacteria, such as E. coli, and any kind of mold spores and organics were not present.

In the following, after examining the suitability of the alkaline purified water prepared by the two-stage filtration system of the present invention as a beverage to provide human body and environmental friendly loess mortar.

The method for preparing ocher mortar of the present invention is the same as the process shown in FIG. 1, and the preferred composition thereof is preferably composed of 0.5 to 10 wt% of charcoal powder in 90 to 99.5 wt% of loess residue steam sterilization filtrate.

The present invention is obtained by putting the composition of the ocher mortar into a drum dryer, mixing the mixture to dry uniformly, and then obtaining the powder in powder form in a moisture-proof package.

Hereinafter, specific configurations and operations of the present invention will be described with reference to experimental examples and examples.
