And red tide relief material and a method for using the same.

Today, it is a eutrophication caused by the inflow of pollutants such as domestic sewage, industrial wastewater, agricultural and livestock wastewater from the land, and the marine ecosystems such as red tide, mudflat, heavy metal pollution, and bad smell are seriously damaged. Phosphorus and nitrogen contained in are very pollutant loads, which leads to eutrophication of rivers, pollution of water and agricultural water, odors and pest damage, and deterioration of the quality of living environment. It is becoming.

Red tide is the eutrophication of water, that is, the phytoplankton multiply when the water contains too much organic nutrients, causing the seawater to turn red. When red tide occurs, oxygen consumption becomes more active, and there is a lack of dissolved oxygen in the water, which can lead to asphyxiation of marine life or poisoned by toxins produced by red tide or secondary substances such as hydrogen sulfide, methane gas and ammonia. The deterioration of the productive capacity of the body of water or the transformation of the ecosystem caused by large-scale red tide hindering the ecosystem material circulation is a blow to the natural world beyond economic value.

As described above, as a method for treating wastewater including red tide, up to now, it has been appropriately combined with physicochemical treatment techniques such as flocculation, sedimentation, filtration and ion exchange, and biological treatment techniques such as biofilm, activated sludge process and anaerobic digestion method. In particular, the method of spraying ocher to the red tide generating area is used as a red tide prevention measure, but the effect is temporary because the effect is not perfect because it is not completely purified to the bottom, and the red tide is revived and regenerated. In addition, the use of chemicals in seaweed and seaweed culture causes a second pollution.

Hereinafter, a preferred embodiment of the present invention will be described in detail.

The inventors of the present invention have studied over a large range of nutrient-poor sediments and red tide phenomena which have severe eutrophication. Therefore, in order to fundamentally improve these phenomena, a method of directly and effectively eradicating contaminants that cause pulverization and red tide is required. As a result, it was necessary to develop a low-cost eco-friendly purification technology that purifies the pollutants themselves, but also the manufacturing process is simple and does not cause secondary pollution.

Therefore, natural mineral material and natural mineral material that can be extracted at inexpensive nature at low cost and raw materials mixed with shells at a constant mixing ratio are dissolved in the seawater for several hours, then precipitated, and then injected into contaminated gaepearl and red tide generating areas. As a result of repeated experiments, not only the purifying effect is continuously exerted with the significantly improved purifying effect, but also the green and red tide remedy materials have been developed with environmental friendliness.

In order to manufacture the gaepal and red tide relief materials used in the present invention, a separate large-scale manufacturing facility is not required in addition to the process of mixing the raw material with seawater, and the method of use also includes the contaminated gaepal with liquid relief materials dissolved in seawater. It is extremely simple because it needs to be sprayed on the red tide occurrence area, and its use effect is also quick and continuous.

In addition, the remedy of the present invention is an environmentally friendly product that is beneficial to the marine environment, and can be used extensively without a total amount restriction on the amount used, and has an advantage that it is not harmful to the human body or beneficial marine organisms because it is an alkaline natural product.

Hereinafter, a detailed description will be given of the raw material for the remedy constituting the preferred embodiment of the present invention.

The natural mineral used in the present invention means a mineral that is naturally produced as a constituent of the original rock, and can be extracted to infinity in nature and can be processed in large quantities, while being easily used in seawater acting as a solvent in the present invention. It has the property of dissolving.

First, ceramics are silicate minerals that elute mineral components of silicon (Si) required for microbial activation. As a porous material, it has a function of adsorbing contaminants because there are many micropores that are easily attached to contaminants. In the present invention, 25 to 35% by weight of the ceramic is added, but if it contains more than 35% by weight, there is a possibility that even the useful substance in the larvae may be lost, it may not be able to use as a nutrient. If the amount is less than 25% by weight, it is difficult to expect the above pollutant adsorption effect.

Germanium is an off-white mineral that is composed of 32 electrons. When a foreign substance comes into contact with it, one of the four outer electrons sticks out and combines with the electrons of the foreign substance, attracting the foreign substance to an empty spot, and converting it into another electron. give. At this time, it is a mineral element that generates, decomposes, neutralizes and removes pure oxygen. In the present invention, while detoxifying the acidified contaminants to an alkaline substance to combine with heavy metals and the like to have a non-toxic detoxification effect. In the present invention, it is preferable to control the content range to 10 to 20% by weight so as to sufficiently exhibit the neutralizing and detoxifying effects of germanium.

Mica is a mica-based rock and is used in many fields because it has excellent heat conduction durability and excellent deodorizing function. The present inventors have determined that the use of mica and other lime minerals can be a better raw material for the remedy. As a result, the present inventors have made a remedy having excellent effects. The main minerals contained in mica are mucovite, phlogopite, biotite, biofluorophlogopite, fluorite, lipidite, paragonite, sericite, and illite. (illite) and the like. In the present invention, while fully exhibiting the deodorizing effect of mica stones, it is preferable to control the content to 7 to 15% by weight in consideration of interaction with other raw materials.

Minerals mean various minerals such as calcium, magnesium and potassium in minerals, and are attracting attention as five nutrients of nutrition along with carbohydrates, fats, proteins and vitamins. Minerals are dissolved in water when there is a lot of the amount of ionization, particularly SiO- group layers so to form the various heavy metals and complex layered complex anion group exists, Ca ^{+ 2} of 8 E-structure in aqueous solution, Mg ^{+ 2,} Cl ^- adsorption on ion such as, but is not apparent, or 18 to 18 ^{2 +} e ^{2 +} structure-forming ions which are Pb, Cd ^{+ 2,} Cu ^{+ 2,} Ni ^{+ 2,} Zn ^{+ 2,} Hg ^{+ 2,} Co ^{+ 2} metal ions Exhibits a strong adsorption effect. In addition, it has been shown to have an acid neutralizing effect and far-infrared radiation effect with other lime minerals of the present invention. In the present invention, it is preferable to control the content to 7 to 15% by weight so as to sufficiently exhibit the desired heavy metal and pollutant adsorption effect, acid neutralization effect, far infrared radiation effect.

On the other hand, the lime component serves as a calcium source, which is one of the essential nutrients in the case of plants, but when used in Gaepul and red tide generating waters as in the present invention, neutralizes the acidic soil at the bottom of the contaminated Gaepul and red tide origin. It is used as an important ingredient that acts as a function of height, promotes the decomposition of bottom soil, and neutralizes the harmful effects of organic and inorganic acids .

Dolomite is composed mainly of magnesium carbonate [CaMg (CO ³ ) ² ] and is one of the most common coarse minerals in carbonate rocks. Like lime minerals such as quicklime and slaked lime, it neutralizes acidic soils with a pH of less than 6.5, supplements nutrients such as magnesium (Mg), removes heavy metals, and promotes microbial activity.

The neutralizing power is greater than that of limestone, and once neutralization is completed, the solubility is small under alkaline conditions, and the consumption is lower than that of limestone with high solubility even under the same conditions. Therefore, it is useful as a neutralizing agent effective for neutralizing acidic leachate in a natural purification manner. In the present invention, while fully exhibiting the neutralization effect and heavy metal removal effect of dolomite, it is preferable to control the content of 5 to 15% by weight in consideration of the mixing ratio with quicklime and slaked lime.

Quick lime is made by heating limestone or dolomite to 1,000 ~ 1,200 ℃ to volatilize carbon dioxide.It is the main ingredient of calcium oxide (CaO), and when combined with moisture, it generates high heat and removes bad smell. . Because of its strong alkalinity, it quickly neutralizes low acidic soils with a pH below 3.5 ~ 5.0.

In the present invention, it is preferable to use 25 to 35% by weight of quicklime, because the quicklime can rapidly change the pH and rapidly change the pH, if it is used in excess of 35% by weight, it is easy to lose useful substances in the falcon as nutrients. You may not be able to use it. However, when used at less than 25% by weight, it is difficult to expect soil neutralization effects.

Slaked lime (Slaked lime or Hydrated lime) is produced by the exothermic reaction by reacting water with quicklime, calcium hydroxide (Ca (OH) ² ) as a main component. Like quicklime, it has strong alkaline and fast-acting properties. In the present invention, while fully exhibiting the neutralizing effect and the heavy metal removal effect of the slaked lime can be added to control the content of 7 to 15% by weight in consideration of the mixing ratio with the quicklime, dolomite.

The quicklime and slaked lime used in the present invention are strong alkalinity and fast-acting, whereas dolomite containing calcium carbonate is weakly alkaline and durable, so that the remedy of the present invention has a neutralizing effect and an immediate effect and sustainability. Rather than using alone, it is preferable to use them by mixing in an appropriate blending ratio.

Fossils are made by crushing and drying shellfish or oyster shells or fossilized materials by depositing them, and it is reported that shells have an effect of improving acidic soil by increasing the soil pH and Ca and Mg contents. have. In neutralizing acidic soils, it has a weak alkaline persistence and has long-term effects. In the present invention, while fully exhibiting the acidic soil reforming effect of the calcite, it is preferable to control the content to 7 to 20% by weight in consideration of the manufacturing cost of the relief material.

The seawater and the raw material for the remedy are preferably mixed in a ratio of 1: 0.05 to 0.4. If the raw material for the remedy is contained in less than 5% of the weight of the seawater, the concentration of the remedy is too low and is contained in the remedy. It is difficult to anticipate the effect of minerals on the pulping and red tide, and the higher the content of the remedy, the better the remedy effect, but when it contains more than 40%, the liquid will turn into strong alkaline or anticipate further pollution purification effect. It is preferable to keep 1: 0.05-0.4 because it is difficult.

The particle size of the raw material to be dissolved in the seawater is preferably a powder product of 200 to 325 mesh bar, if less than 200 mesh is used, the particle size is too large to obtain a liquid purifier in the form of a solution in which the raw material is evenly dispersed If the particle size exceeds 325 mesh and the raw material particle size is too small, it may be difficult to expect to effectively adsorb or settle the contaminants, so that it is controlled to about 200 to 325 mesh.

Looking at the manufacturing method of the environment-friendly liquid gaepal and red tide relief material according to the present invention,

First, the raw materials of powdered natural minerals and crushed stone, which are crushed into 200 to 325 mesh, are put into a stirrer about 60 to 90 times per minute, mixed with seawater, dissolved for about 4 to 10 hours, and then manufactured by precipitation. In this process, the dissolved precipitated water is used as a liquid remedy, and the produced sludge may be recycled as a second purification agent such as compost or landfill, rather than being classified and treated as a specific waste as in the prior art.

Looking at the method of relieving low acid acid gaepul and using the red tide relief material according to the present invention to rescue red tide,

Although the method of spraying the liquid remedy material according to the present invention on the sea of Gaepal or red tide relief area may be used, more preferably in order to have a complete relief effect to the bottom of the area of interest, that is shown in FIG. Install a tillage purifying device having a liquid relief inlet and an outlet, and inject the liquid relief material of the present invention into the relief inlet of the tillage purifier, and the relief material flows through a relief outlet adjacent to the target area floor. Effectively and completely remedy by causing the plowing action of plowing, or burial, mixing, and crushing the soil to be improved, such as low quality sapphire, at the bottom of the target area by the height difference between the inlet and the outlet and the pressure of the inflowing liquid. It is desirable to have the effect of the substance on the entire soil.

As described above, according to the present invention, first, the acidified low-gap and red tide can be reduced and improved, and the microorganisms causing red tide can be absorbed and decomposed to exhibit the effect of improving pollution in a short period of time.

Second, the use of environmentally friendly natural minerals do not produce harmful substances or secondary pollution problems.

Third, using natural mineral materials that can be infinitely extracted at low cost in nature, does not require large-scale manufacturing facilities, and can provide a simple and eco-friendly gas and red tide relief material.
