6 is a state diagram showing a process of decomposing contaminants through the pores of the biostone ball 140 according to the present invention, and FIG. 7 is a cross-sectional view showing the biostone ball 140 according to the present invention.

The biostone ball 140 includes a plurality of carriers 141 , a first coating layer 142 , and an adhesive layer 143 .

The carrier 141 may be at least one selected from the group consisting of gravel, ceramic, plastic, glass, and vermiculite.

The first coating layer 142 is coated on the carriers 141, and 1 to 20 parts by weight of an organic acid, preferably 5 to 10 parts by weight, based on 100 parts by weight of the petroleum resin; 0.01 to 10 parts by weight of cyclohexylamine nitrite, preferably 0.1 to 3 parts by weight; and 0.01 to 5 parts by weight of calcium silicate, preferably 0.1 to 1 part by weight.

At this time, the first coating layer 142 is coated on the surface of the carrier 141 to improve bonding between the carrier 141 and the adhesive layer 143 .

The thickness of the first coating layer 142 is 0.01 to 1 mm, preferably 0.05 to 0.5 mm.

However, when the thickness of the first coating layer 142 is less than the lower limit of the preferred range, the bonding force between the first coating layer 142 and the adhesive layer 143 may be reduced.

The petroleum resin is a material that improves the bonding strength between the first coating layer 142 and the adhesive layer 143, and specifically, may include rosin resin, terpene resin, or a mixture thereof, preferably rosin resin. can

In addition, the organic acid improves the bonding force between the carrier 141 and the first coating layer 142, so that when the adhesive layer 143 is formed directly on the carrier 141, the adhesive layer 143 is the carrier 141 during long-term use. As a substance for preventing the phenomenon of falling off, specifically, at least one selected from the group consisting of adipic acid, fumaric acid, stearic acid, oleic acid, filmitic acid, lauryl acid, (anhydrous) maleic acid, and (anhydrous) terephthalic acid can be mentioned. .

In addition, when the content of the organic acid is less than the lower limit of the preferred range, the bonding force between the carrier 141 and the first coating layer 142 may be reduced, and when it exceeds the upper limit, the carrier 141 and the first coating layer 142 . Although the bonding strength between the two is improved, the bonding strength between the first coating layer 142 and the adhesive layer 143 may be decreased.

In addition, the cyclohexylamine nitrite is used together with an organic acid to improve the bonding force between the carrier 141 and the first coating layer 142 as well as to improve the strength of the first coating layer 142 .

When the content of cyclohexylamine nitrite is less than the lower limit of the preferred range, the bonding force between the carrier 141 and the first coating layer 142 and the strength of the first coating layer 142 may be reduced. Cracks may occur during the curing process.

In addition, the calcium silicate may be used together with the petroleum resin to improve the bonding strength between the first coating layer 142 and the adhesive layer 143 .

When the content of calcium silicate is less than the lower limit of the preferred range, the bonding force between the first coating layer 142 and the adhesive layer 143 is lowered, and when it exceeds the upper limit, the first coating layer 142 and the adhesive layer 143. The bonding strength may be reduced.

The adhesive layer 143 is applied to the surface of the first coating layer 142 coated on the surfaces of the carriers 141 to bond the carriers 141 to each other.

At this time, in the adhesive layer 143, epoxy amine adduct and polyamide are mixed in a weight ratio of 1:0.6-0.8 with respect to 100 parts by weight of a resin in which an epoxy resin and calcium carbonate are mixed in a weight ratio of 1:0.1-0.3. 40 to 60 parts by weight of the mixed curing agent, 0.5 to 1 parts by weight of carbon black, 5 to 10 parts by weight of silicon dioxide, 1 to 8 parts by weight of aluminum oxide, 1 to 30 parts by weight of fly ash, 0.01 to 10 parts by weight of metakaolin, poly 0.01 to 10 parts by weight of the oxyethylene-polypropylene glycol copolymer and 0.01 to 10 parts by weight of calcined dolomite.

The resin agent is a mixture of epoxy resin and calcium carbonate in a weight ratio of 1: 0.1-0.3, and when the epoxy resin and calcium carbonate do not satisfy the above range, a resin agent having a viscosity of 8,000 ± 1,000 cps cannot be obtained. , thus, the adhesive force of the adhesive layer 143 may be reduced.

In addition, the curing agent is a mixture of epoxy amine adduct and polyamide in a weight ratio of 1: 0.6-0.8, and when the epoxy amine adduct and polyamide do not satisfy the above range, a curing agent having a viscosity of 200 ± 50 cps is used. cannot be obtained, and thus the adhesive force of the adhesive layer 143 may be reduced.

When the content of the curing agent is out of the preferred range, the adhesive strength of the adhesive layer 143 may be reduced.

In addition, the carbon black not only protects the light-sensitive epoxy resin from light, but also expands the surface area to allow a large amount of microorganisms to attach.

When the content of the carbon black is less than the lower limit of the preferred range, the epoxy resin is aged by light, and as time goes by, the bonding strength is rapidly lowered and the amount of microorganisms attached may be lowered, and if it exceeds the upper limit, the adhesive layer 143 strength may be reduced.

In addition, the silicon dioxide is a material that significantly improves the compressive strength when used with an epoxy-based resin, and when the content of silicon dioxide is less than the lower limit of the preferred range, the compressive strength may decrease, and if it exceeds the upper limit, voids may interfere with the formation of

In addition, the aluminum oxide is used together with an epoxy resin and silicon dioxide to significantly improve the compressive strength. When the content of aluminum oxide is out of the above range, it may be lower than the required compressive strength (3.8 MPa).

In addition, the fly ash is a material having pozzolanic properties to improve the strength and durability of the adhesive layer 143 . When the content of fly ash is less than the lower limit of the preferred range, strength and durability may be reduced, and if it exceeds the upper limit, the formation of pores may be prevented.

In addition, the metakaolin also has pozzolanic properties, and when used together with the fly ash, the strength and durability of the adhesive layer 143 are significantly improved. If the content of metakaolin is less than the lower limit of the preferred range, strength and durability may not be improved, and if it exceeds the upper limit, strength and durability may be rather reduced.

In addition, the polyoxyethylene-polypropylene glycol copolymer prevents cracks from being formed in the adhesive layer 143 during curing.

In addition, the calcined dolomite is calcined by calcining dolomite, a carbonate mineral, at 900 to 1,000 ° C. Among the total components of calcined dolomite, magnesium oxide (MgO) is 32 to 35 wt%, calcium oxide (CaO) is It contains 50 to 55% by weight, and when used with a polyoxyethylene-polypropylene glycol copolymer, a large number of pores can be easily formed. In addition, it may be used as a source of calcium ions required for the pozzolan reaction, thereby contributing to improving the strength and durability of the adhesive layer 143 .

When the content of the calcined dolomite is out of the preferred range, desired pores may not be formed and microorganisms may not be attached in a large amount.

The adhesive made of the above materials has an adhesive force of 110 to 150 kg/cm 2 , so the adhesiveness of the first coating layer 142 is excellent, and the contact life time is 30 to 40 minutes, so re-adhesion is easy within the pot life. .

In addition, the biostone ball 140 is coated on the surface of the adhesive layer 143 and includes a second coating layer 144 formed in a porous structure, and the pores of the second coating layer 144 are filled with microorganisms. Microorganisms that stably grow and multiply through the pores can decompose organic matter to perform self-cleaning.

The second coating layer 144 is coated only on the outside of the biostone ball 140 by spraying an organic/inorganic coating agent on the surface of the cured biostone ball 140 by high pressure injection (ie, the biostone ball 140 ). ) is coated on the adhesive layer 143 on the outside), and is not coated on the inside.

The second coating layer 144 is coated with a high-pressure spray to form a plurality of pores and a plurality of through-holes together. This is because the organic/inorganic coating agent has a higher content of solids compared to the content of the resin, so pores are formed during coating by high-pressure spraying, and a through hole is formed as some solids fall off after being attached to the upper surface of the adhesive layer 143. . When the organic/inorganic coating agent is coated by a method such as general spraying or dipping instead of high-pressure spraying, voids are not properly formed in the first coating layer 142, and no through-holes are formed at all. The void is also formed as a space between the bound inorganic particles.

In addition, a large amount of microorganisms may be filled (attached) to the plurality of pores formed in the second coating layer 144 . The microorganisms attached to the adhesive layer 143 and the second coating layer 144 are not particularly limited as long as they can self-purify contaminated water, but preferably at least one selected from the group consisting of multiple useful microorganisms and bacteria. there is.

The thickness of the second coating layer 144 is 0.05 to 1 mm, preferably 0.1 to 0.5 mm. When the thickness of the second coating layer 144 is less than the lower limit of the preferred range, a large amount of voids are not generated. ability may be reduced.

The second coating layer 144 may include 1 to 20 parts by weight, preferably 5 to 10 parts by weight of Schungit powder, based on 100 parts by weight of the elastomer resin; 1 to 10 parts by weight of seaweed powder, preferably 5 to 8 parts by weight; 0.01 to 10 parts by weight of iron oxide, preferably 2 to 8 parts by weight; 1 to 15 parts by weight of magnesite, preferably 5 to 10 parts by weight; 1 to 15 parts by weight of alginate, preferably 5 to 10 parts by weight; 1 to 15 parts by weight of dolomite, preferably 5 to 10 parts by weight; 0.1 to 5 parts by weight of organic fibers, preferably 2 to 4 parts by weight; 0.1 to 5 parts by weight of inorganic fibers, preferably 1 to 3 parts by weight; 1 to 10 parts by weight of illite, preferably 5 to 8 parts by weight; and 1 to 10 parts by weight of perlite, preferably 5 to 8 parts by weight.

The elastomer resin provides elasticity to the biostone balls 140 to prevent the biostone balls 140 from being damaged by contaminated water, and also connects and fixes inorganic materials to each other.

In addition, the schungit powder itself can purify contaminated water and perform antibacterial action, as well as attach a large amount of microorganisms.
