Description

[Technical Field]

[0001] The present invention relates to a river respiratory ecology restoration agent for polluted natural water areas that uses the natural mineral lumilite, and a method for producing the same. [Background technology]

[0002] The main natural silica materials used in the treatment of most water and soil pollution, zeolite and bentonite, use a considerable amount of aluminum-based coagulant as an auxiliary agent to double the cation exchange capacity for coagulating anionic suspended solids, or use algicides, which are toxic chemicals that kill green algae.

[0003] However, side effects of these aluminum-based flocculants include the toxicity of aluminum, a heavy metal that can cause dementia, and the problem of a sudden drop in pH in the target water body has been raised. Therefore, these aluminum-based flocculants are primarily used in water purification plants and wastewater treatment plants. However, while aluminum-based flocculants are used when an algal bloom warning is issued, which indicates the sudden outbreak of toxic cyanobacteria at a cell count of 1 million cells / mL or more in natural water bodies such as rivers, lakes, drinking water dams, reservoirs, and groundwater, they are partially effective at flocculating water quality. However, aluminum levels in drinking water far exceed 0.2 mg / L, making them a major cause of secondary pollution due to ecological destruction caused by the heavy metal aluminum. Summary of the Invention [Problem to be solved by the invention]

[0004] We aim to protect water resources by preventing a sudden drop in pH in target water areas using water treatment agents, removing the toxicity of aluminum heavy metals, which are substances that cause dementia in water areas, and preventing economic losses and serious declines in ecological recovery caused by the loss of inorganic materials such as sand, gravel, and loess, which are necessary for natural ecological restoration, along with odorous organic substances, during large-scale dredging to remove odorous organic substances.We also aim to restore and maintain ecologically clean and safe water quality in natural water areas such as rivers, lakes, drinking water dams, and groundwater, which are becoming more polluted every day. [Means for solving the problem]

[0005] Clinobutilolite 65-75% by weight, kaolinite 5-15% by weight, montmorillonite 3-10% by weight, lomontite 2% by weight, perlite 2% by weight, light rare earths 0.1% by weight, neodymium 0.01% by weight, dysprosium 0.01% by weight, quartz 1-2% by weight, pozzolan 5-9% by weight, Barley rice It contains 2-3% by weight of stone, the same proportions of freeze-dried hemp, polyglutamic acid (PGA) and 0.006-0.01% by weight of palm sap.

[0006] Clinobutilolite, kaolinite, montmorillonite, lomontite, pearlite, light rare earths, neodymium, dysprosium, quartz, pozzolan, Barley rice The process includes the following steps: a first step of crushing the stone, freeze-dried hemp, polyglutamic acid (PGA), and palm sap and then sieving it through a 350-400 mesh; a second step of stirring the powder obtained after the first step at 110-130°C for 5 minutes and then allowing it to cool naturally in room temperature air for 24 hours; a third step of stirring the powder obtained after the second step at 260-370°C for 5 minutes and then allowing it to cool naturally in room temperature air for 24 hours; a fourth step of heating the powder obtained after the third step at 410-470°C for 5 minutes and then allowing it to cool naturally in room temperature air for 24 hours; and a fifth step of stirring the powder obtained after the fourth step for 5 minutes and then allowing it to cool for 24 hours before packaging. [Effects of the Invention]

[0007] This invention does not pose any risk of sudden pH drops in the target water area or aluminum heavy metal toxicity, which is a cause of dementia. By spraying a very small amount (100-200 ppm) by weight depending on the pollution concentration, it not only improves the water quality of polluted natural water areas over the long term, but also makes use of natural minerals with high particle strength. The complex natural silicon component of Lumilite, with a specific gravity of 2.4, sinks to the bottom and, due to the high surface charge of the positive ions on the surface, adsorbs and coagulates with suspended solids in the water, then settles down by gravity, providing a coating thickness that is sufficient to suppress the elution of nutrients and heavy metals from the bottom sediment. Lumilite accumulates about 1 mm below the bottom surface of a body of water, forming a strong bridge with the adsorbed suspended solids. Due to its high particle strength, Lumilite acts as a barrier, inhibiting the elution of nutrients and heavy metals from the bottom sediment after settling, preventing their re-elution and thus blocking the elution of odorous and sedimentary substances. In addition to decomposing odor-causing organic matter, the porous structure of Lumilite, which aggregates and settles on the bottom, provides a habitat for aerobic bacteria that decompose odor-causing organic matter in the bottom sediment, serving as a habitat and nutrient source for microorganisms and aerobic bacteria, and after settling, promoting the proliferation of plant-based microorganisms. These plant-based microorganisms act as decomposers of organic matter in the bottom sediment, naturally decomposing the organic matter. After several months to six months, they will significantly decompose the organic matter in the bottom sediment, revitalizing the bottom sediment and restoring its natural state. Due to their excellent odor and sediment quality improvement effects, Lumilite can be applied to a wide range of severely polluted water sites. Furthermore, the environment can be protected by simply spraying the product on the polluted water surface, rather than by plant construction, and has the advantages of simple construction, low cost and high efficiency.

[0009] Meanwhile, from October 12, 2021 to November 23, 2021, as part of a water quality improvement cooperation project at Changhyeon Reservoir in Changhyeon-dong, Gangneung, Gangwon Province, which is managed by the Korea Rural Community Corporation, the water quality was improved using the natural mineral Lumilite, a natural water quality improver of the present invention, and the effects before and after the water quality improvement were analyzed and data was obtained.As a result, Gangneung Changhyeon Reservoir showed very poor (VI) water quality as of September 29, 2021, with TOC (9.4 mg / L), turbidity (2,520 NTU), total phosphorus (0.453 mg / L), and chlorophyll a (107.7 m / m3), indicating that water quality management was required.

[0010] Water quality (COD, SS, TP, chlorophyll a, TOC, turbidity, transparency) of Changhyeon Reservoir was significantly improved by using the natural mineral water treatment agent Lumilite, and there was no ecotoxicity to Daphnia or bioluminescent bacteria. There was also no impact on other organisms such as fish and benthic macroinvertebrates.

[0011] <Experimental Examples> All tests were carried out using a mixture of 70% by weight of clinobutyrolite, 10% by weight of kaolinite, 5% by weight of montmorillonite, 2% by weight of lomontite, 2% by weight of perlite, 0.1% by weight of light rare earths, 0.01% by weight of neodymium, 0.01% by weight of dysprosium, 1% by weight of quartz, 6% by weight of pozzolan, Barley rice The mixture consisted of 2% by weight of stone, and the same proportions of freeze-dried hemp, polyglutamic acid (PGA), and palm sap. 0.007% by weight (see Figures 2 and 3).

[0012] [Table 1]

[0014] In addition, from October 21 to December 11, 2021, the water quality of Chuncheon Uiam Lake (a dam for drinking water in the Seoul area) was improved using the natural water quality improver Lumilight of the present invention as part of a water quality improvement cooperation project between the Korea Water Ecology Restoration Association, Chuncheon City, and Korea Hydro & Nuclear Power. The effects before and after the water quality improvement were objectively analyzed, and post-improvement (environmental) impact survey data was obtained. As a result, as of October 21, 2021, Chuncheon Uiam Lake (Gongjicheon) had high values ​​for all water quality items at all points, with SS of 3.3 to 4.7 mg / L, which is equivalent to the living environment standard level II to III, TP of 0.034, 0.018, 0.038, and 0.015 mg / L, which is equivalent to the living environment standard level II to III, and chlorophyll a (Chl.a) at around 6 μg / L.

[0015] By using the natural mineral water treatment agent Lumilight, the water quality of Chuncheon Uiam Lake (Gongjicheon) was also improved significantly (COD, SS, TP, chlorophyll a, TOC, turbidity, transparency), and there was no ecotoxicity to Daphnia or bioluminescent bacteria. Furthermore, there was no impact on aquatic organisms such as killifish (see Figures 4 and 5).

[0018] Before describing in detail the embodiments of the present invention that specifically embody the technical idea of ​​the present application by presenting specific embodiments, the terms and words used in the specification and claims of the present application are to be interpreted only in their ordinary or dictionary meanings. The scope of protection of the present specification should not be interpreted as meanings and concepts that match the technical idea of ​​the invention. Furthermore, the objectives or effects presented in the present invention do not mean that a particular embodiment should include all of them or should include only such effects, and therefore the scope of the present invention should not be understood to be limited thereby.

[0019] Unless otherwise defined, all terms used herein have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention pertains. Terms defined in commonly used dictionaries should be interpreted to be consistent with the contextual meaning of the relevant art, and cannot be interpreted as having an ideal or overly formal meaning that is not clearly defined in the present invention.

[0020] The present invention is a natural mineral lumilite ecological restoration agent and a method for producing it.

[0021] The present invention will be described in detail below.

[0022] The Lumilite of the present invention is selected from natural zeolites and contains 65-75% clinobutyrolite, which has particularly high adsorption and ion exchange capabilities and is excellent for water purification; 5-10% kaolinite, which is aged soil; 3-10% montmorillonite, a type of clay mineral with a monoclinic crystal system; 2% lomontite, a type of zeolite belonging to the monoclinic crystal system; 2% perlite made from perlite and obsidian; 0.1% light rare earth elements; 0.01% neodymium and 0.01% dysprosium, which are medium rare earth elements; 1-2% quartz; and 5-9% pozzolan, a type of concrete admixture made from mineral powder such as volcanic ash. Barley rice It contains 2-3% stone, the same proportions of freeze-dried hemp, PGA (polyglutamic acid) extracted from koji soy sauce and natto, and 0.006-0.01% palm sap.

[0023] Lumilite of the present invention is a water purifier made from clinoptilolite, a microporous mineral naturally formed when volcanic lava solidifies. When phosphorus (P), which causes greening, and suspended solids (SS), which cause water pollution, are adsorbed into the porous material through ion exchange, the clinoptilolite, which has become heavier due to the aggregation of phosphorus and suspended solids, sinks to the bottom, promoting water quality improvement. By utilizing the excellent adsorption properties of the ion-exchanged Lumilite, it adsorbs and precipitates and removes underwater pollutants, such as plankton, which causes greening, thereby purifying the water.

[0024] The present invention is a composite material containing 65 to 75% by weight of clinobutyrolite, 5 to 15% by weight of kaolinite, 3 to 10% by weight of montmorillonite, 2% by weight of lomontite, 2% by weight of pearlite, 0.1% by weight of light rare earths, 0.001% by weight of neodymium, 0.001% by weight of dysprosium, 1 to 2% by weight of quartz, 5 to 9% by weight of pozzolan, Barley rice The process includes the following steps: (1) grinding 2-3 wt% of sappan, 0.002-0.0033 wt% of freeze-dried hemp, 0.002-0.0033 wt% of freeze-dried polyglutamic acid (PGA), and 0.002-0.0033 wt% of freeze-dried palm sap and sieving it through a 350-400 mesh; (2) stirring the powder obtained after the first step at 110-130°C for 5 minutes and then allowing it to cool naturally in room temperature air for 24 hours; (3) stirring the powder obtained after the second step at 260-370°C for 5 minutes and then allowing it to cool naturally in room temperature air for 24 hours; (4) heating the powder obtained after the third step at 410-470°C for 5 minutes and then allowing it to cool naturally in room temperature air for 24 hours; and (5) stirring the powder obtained after the fourth step for 5 minutes and then allowing it to cool for 24 hours before packaging.

[0025] The clinoptilolite of the present invention contains 67 to 68% silicic acid (SiO2), 11 to 14% aluminum (Al2O3), 1 to 1.67% iron oxide (Fe2O3), 0.6 to 0.7% magnesium oxide (MgO), 2 to 3.42% calcium oxide (CaO), 1 to 1.25% sodium oxide (Na2O), 2.92% potassium oxide (K2O), and 0.064% zinc oxide (P2O5), and has a CEC (cation exchange capacity) of 140 to 155 (me q / 100g) and has a very large cation exchange capacity.

[0026] In the clinoptilolite mentioned above, the balance between negative (-) and positive (+) charges is disrupted due to the partial substitution of Si4+ with Al3+ within the tetrahedron, resulting in a structurally negatively (-) charged state. By substituting cations for the negatively (-) charged state, the surface is substituted with a positively (+) charged state, and these surface cations can be easily substituted with other surrounding cations, resulting in a high degree of cation substitution, but also making anion substitution possible.

[0027] Therefore, it is a mineral that is often used as a catalyst, adsorbent, detergent additive, etc. because it is good at replacing nitrogen oxides that exist in gaseous form, detoxifying active oxygen through anion replacement, and contributing to the neutralization of pollutants and eliminating odors.It is a solid oxide, and the bonding method of its constituent atoms is specific, so the properties of the constituent atoms do not change even when heated.The basic unit is very simple, TO4, centered around silicon and aluminum atoms, but these can be bonded three-dimensionally to create a variety of structures, and it is a crystalline complex oxide in which silicon and aluminum atoms form a regular tetrahedral coordination structure with oxygen atoms and bond.

[0028] The surface exposed on the granular surface and unrelated to the pores is called the inner pore surface. Even if clinoptilolite is a fine powder, the inner pore surface is very large, and when used as an adsorbent or catalyst, it is mostly the inner pore surface. This does not break down even when heated or evacuated.

[0029] Kaolinite, with the general formula Al2Si2O5(OH)4, is known by various names depending on its crystalline structure. Examples include kaolinide, halloysite, dickite, and nyclite. Kaolinite aids in the settling ability of microorganisms and serves as a limiting source of nitrifying microorganisms in biological reactors, supporting their activity. It accelerates the growth rate and promotes energy metabolism by supplying trace elements necessary for the growth and energy metabolism of nitrifying microorganisms. In particular, this component must be used in the treatment process with a moisture content of less than 35% at the time of injection; the higher this moisture content, the lower the efficiency. Therefore, a drying time of at least two hours is required. These selected components can be used as microbial supports. In other words, in the case of nitrifying microorganisms, the increased SRT (Sludge Retention Time) can induce an increase in the quantity of these components, favoring the growth of attached-growing microorganisms as well as suspended microorganisms.

[0030] Montmorillonite is a type of fire clay, an SiO2-Al2O3 mineral containing approximately 59% SiO2, approximately 14% Al2O3, and approximately 3.5% Na2O. It is widely distributed among feldspars and clay minerals in Japan, and when used in combination with non-feldspar minerals, it complements each other due to its adsorption and ion exchange properties resulting from its porous nature, which is a characteristic of SiO2-Al2O3 minerals.

[0031] Although montmorillonite does not dissolve in water, it absorbs water from aqueous solutions and swells to 8-12 times its particle size, thereby complementing its role in adsorbing pollutants. As a high CEC clay mineral, it has a large surface area and excellent CEC (cation exchange capacity) among clay minerals, allowing water to escape freely between the crystalline units, causing it to expand and contract depending on the amount of water it contains, and its bacteriostatic properties prevent algae from regrowing in settled sediments.

[0032] Lomontite is found in cavities and thermal poles of basic igneous rocks such as basalt and diabase tuff, and sometimes occurs as a secondary mineral in granite and gneiss. It is also found in gold veins and other deposits. Its crystalline structure loosens the bonds between its atoms, releasing the water that fills them under high heat, but the skeleton remains intact, allowing it to adsorb other fine particles. This property is used as an adsorbent, a molecular entity that separates fine particles of different sizes.

[0033] Perlite is used as an adsorbent in the reaction vessel due to its large specific surface area, which allows for easy attachment of microorganisms. By forming a carrier using perlite, which is lightweight and highly porous, microorganisms are uniformly adsorbed on the surface and internal pores of the perlite, which is advantageous for the formation of microbial communities. It provides a carrier with excellent adhesion ability, which helps microorganisms grow steadily and is resistant to environmental changes such as temperature, moisture, and pH.

[0034] Perlite, obsidian, etc. are broken down and then baked at around 1,000°C to make them porous for use.

[0035] Rare earths are classified into light rare earths and medium rare earths, and light rare earths, neodymium, and dysprosium are used. It is a natural clay component and does not affect the aquatic ecosystem. It prevents the denutrition of rivers and streams by removing the pollutant phosphorus through an "adsorption and precipitation" mechanism, and blocks the occurrence of greenery at the source. Its phosphorus removal function is not limited to a short period of time, but rather works in the water for 2-3 years to capture phosphorus that flows in, making it an economical and easy-to-use product.

[0036] Quartz is a type of silicate mineral with a silica content of 95-97% by weight or more. Quartz purifies water and supplies oxygen to the water. Quartz also emits far infrared rays, which have deodorizing and antibacterial effects, and can convert water into alkaline water.

[0037] Pozzolans contain highly active silica, which combines with Ca(OH)2 to form CSH.

[0038] Barley rice The stone is a weak stone belonging to quartz porphyry, and belongs to the granodiolite group of igneous rocks. Its main components are silica anhydride and aluminum oxide, with a small amount of ferric oxide. Barley rice The stone has 30,000 to 150,000 pores per cm3 and has strong adsorption properties, so it can not only adsorb and remove toxic substances and suspended solids contained in water, but also exchanges ions with heavy metals, so it is used as a water purifier that can remove harmful metals.

[0039] Equal parts of freeze-dried hemp, polyglutamic acid (PGA), and palm sap, rich in vegetable tannins, were derivatized and modified to obtain low concentrations (e.g., <500 ppm) of residual formaldehyde through conventional phenol / aldehyde or Mannich reactions. This was then combined with the inorganic coagulants alum and iron(II)(III) chloride to produce a vegetable-based wastewater treatment agent. This agent facilitates the flocculation and sedimentation of difficult-to-decompose wastewaters, such as dyeing, leather, and food wastewater, to form insoluble precipitates. In particular, it not only coagulates and removes pigments contained in wastewater, but also binds and immobilizes vegetable tannins to solid waste (shaving scraps). Vegetable tannins typically possess multiple adjacent phenolic hydroxyls, giving them the advantage of special affinity for most metal ions. Therefore, vegetable tannins can be useful as adsorbent components for the removal of various metal ions from aqueous solutions.
