Description

{A method of preparing a water purification agent by selecting minerals from rocksite sludge and mixing feldspar with limestone}

The present invention relates to a method for producing a water purification agent in which minerals are selected from seoksan sludge and feldspar and limestone are mixed. Etc.) by centrifugation and extracting, mixing feldspar and limestone to purify and remove red algae and green algae, remove odors from wastewater and animal feces, and purify minerals from seoksan sludge that purifies water from water and sewage. And it relates to a method of manufacturing a water purification agent in which feldspar and limestone are mixed.

Seoksan is a mountain with many stones or rocks, and is a place where workers in the field can do mining. Accordingly, workers can perform mining work in seoksan, collect the desired raw stone, process and sell it, and the industry can be achieved.

At this time, when the period permitted to collect the raw stone from the masonry has expired, or when it is determined that the petroleum is in need of restoration, the government-licensed waste can be buried in the masonry. As a related technology, Korean Registered Patent Publication No. 10-1528674 ("Waste reclamation method by step-by-step embankment layer using waste-rock acid or meta-myeon"), which is a method of landfilling waste using waste-rock acid or metabolism, has been disclosed. have. The above method discloses a configuration in which a thin-film ordering layer is installed on the lower surface of a puddle created after mining the stone, and waste is buried in that portion.

The above method can be effective because it can landfill the waste along with recovering seoksan, but the problem is that the waste to be landfilled at the site is not only approved by the government, but also designated waste may be landfilled. These designated wastes are not publicly committed, and are generally illegally generated outside the supervision of relevant ministries at the relevant sites.

The reclamation of designated wastes caused by the above illegal acts contaminates the surrounding environment and can be fatal to the health of nearby residents, which is a major problem in society. Furthermore, a lot of cost and time are invested in re-digging the pollutants that are currently buried in the Seoksan Restoration Site, and this has a problem that additionally occurs in the process of disposing of the buried designated waste.

However, since it is not appropriate to treat such seoksan sludge, various methods of recycling these sludges have recently come to be suggested.

On the other hand, the exact cause of the occurrence of red tide has not yet been identified, but it is reported that moderate insolation, water temperature of about 15°C to 25°C, and abnormal increase in nutrients are acting as the main factors. Once a red tide occurs, a large amount of plankton rapidly consumes the amount of dissolved oxygen in the water, so fish living in the waters near the red tide can die collectively. It is spraying.

This method of spraying loess in the waters where the red tide occurs while moving with loess on a large ship is recommended in that it does not pollute the water quality above all else, but a lot of equipment and manpower are required to relieve the red tide that occurs in the vast waters. In addition to the disadvantages, there is a problem that goes against the preservation of marine ecosystems in that if loess is oversprayed, adherent organisms such as abalone and algae may die.

On the other hand, when a red tide occurs, fishermen at a cage farm that raises fish using a cage net are the places that are most affected.If you do not prepare equipment for red tide and a large amount of loess in advance in preparation for the occurrence of red tide, Not only is the damage caused by the red tide inevitable, and most of the fishermen in the small cage farms cost real money.

There is a problem that it is difficult in reality to prepare such equipment, which can take an enormous amount.

Feldspar (K, Na, Ca, Ba , Rb, Sr, Fe) Al (Al, Si) has a complex chemical composition of ₃O _8. Depending on the type of metal element it contains, it is classified into alkali feldspar such as jangseok and misa feldspar, plagioclase such as soda feldspar and calcium feldspar, and barium feldspar.

It is the most widely calculated among all minerals and accounts for 60% of the crust. When pure, it is close to white and transparent, but has a different color depending on impurities. Mohs hardness is 6 and specific gravity is 2~2.7. Depending on the type, it shows a crystal structure of monoclinic or triclinic, and has a cleavage and twin crystals in two directions.

Feldspar is calculated as the main constituent mineral of igneous rock and gneiss. However, the types of deposits that are economically subject to execution include those formed by alternating alkali reactions along the fissures in granite and gneiss, and those produced as accompanying minerals of macrocrystalline granite and feldspar. High quality is achieved when it is produced as a coarse granular dyke and a feldspar dyke.

Limestone is also referred to as limestone, and often appears as a mixture of dolomite. Limestone with a content of magnesium carbonate (MgCO3) within 5%, paleolithic limestone with a content of 5-10%, 10-50 % Is called dolomite lime, and 50% or more is called dolomite. In general, limestone contains minor minerals, especially silicic acid, feldspar, clay, and pyrite. It contains 鐵石) and Neungcheolseok (菱鐵石).

The hardness varies slightly depending on the content of these impurities, but is generally about 3 or 4, and the specific gravity is around 2.7. The color is white and gray, but depending on the content of impurities, it may be brown or red. Limestone is a global sedimentary rock. It occupies a quarter to a fifth of the total sedimentary rock layer.

Here, the reason for pulverizing stone, soil, feldspar, and limestone into 290-345 mesh powder is to facilitate the chemical reaction in which the mixture is agglomerated with a water purifier. At particle sizes exceeding 345 mesh, lumps are not well agglomerated. Does not occur.

The water purifying agent as described above has excellent ability to remove pollutants, so when applied to water pollution prevention facilities and odor removal such as liquids and feces, very excellent effects can be exhibited.

On the other hand, if floating substances contained in seawater or freshwater (groundwater) are introduced by occupation from farms, lakes, rivers, etc., there is a concern that they will be introduced along with pathogens, and red tide and green algae are frequently occurring due to recent ocean pollution and rising seawater temperature. , When contaminated water is introduced, various problems such as aquaculture, lakes, and fish death in rivers may occur due to the occurrence of diseases and difficulty breathing such as fish. The excellent chemical oxygen requirement (CDO), total nitrogen removal efficiency, and total phosphorus removal efficiency means that the removal efficiency of suspended matter on water is excellent.

The use of the water purifying material of the present invention may be different according to the particle size distribution, and the finished powder product may be used to adjust the particle size to be manufactured according to the purpose, and then supplied to be usable.

The present invention as described above enables extraction of minerals such as gold, silver, copper, and non-metals contained in seoksan sludge consisting of stones and soil remaining from seoksan, and mixing the remaining seoksan sludge and feldspar and baking them in a blast furnace. It is to provide the effect of resolving red tide and green algae, as well as a water purification agent and a purification agent used for purposes.

In addition, when used as a water purifying agent and a purifying agent, the water purifying agent emits radiation from natural rock powder through natural rock powder, feldspar, and limestone, providing a very beneficial and environmentally friendly effect to humans.

In addition, it can be effectively used for removing odors from wastewater and animal feces, in addition to water purification and purification treatment agents.

In the present invention, after the development of stone or rocky seoksan is completed, the stone and soil are crushed to powder, and the centrifugal separator is used to select minerals such as gold, silver, copper, and non-metal to be reused. It is to provide a very useful invention in which feldspar and limestone are pulverized and supplied to the resulting sludge to remove water purifying agents and odors that are harmless to the human body, and to re-use a purifying agent that eliminates red and green algae as natural ingredients.
