Abstract
The present invention relates to a algal remover and a method for producing the same, and more particularly, to a powdery algaecalter having a trap of hydrogen peroxide in a three-dimensional branched structure inorganic material and a method for producing the same.
Description
The present invention relates to a algal remover and a method for producing the same, and more particularly, to a powdery algaecalter having a trapped hydrogen peroxide solution in a three-dimensional branched structure inorganic material and a method for producing the same.
Generally, green algae phenomenon refers to the phenomenon that algae, which are phytoplankton, are greatly increased in an eutrophic lake or a stream having a slow flow rate, and the water is changed into green. When the eutrophication phenomenon occurs in the sea (stagnant water), it is reddish by plankton, which is called red tide phenomenon.
Specifically, eutrophication refers to the deterioration of water quality caused by excessive inflow of organic matter (nitrogen or phosphorus) contaminated in stagnant water bodies such as lakes, coastal waters and rivers. When a large amount of nutrients are introduced into stagnant waters, the algal blooms grow excessively and the green algae corrodes the waters to decay. Nutrients for eutrophication include ammonia, nitrite, nitrate, organic nitrogen compounds, inorganic phosphates, organic phosphates and silicates, which are mainly imported from domestic sewage, factory wastewater or fertilizer or organic materials. This can be a good nutrient for algae, including microbes and phytoplankton.
However, when a large amount of nutrients are supplied, the number of bird species explosively increases and the amount of organic matter deposited at the bottom of the lake or river is increased, and the microorganisms are decomposed from the deposited organic matter and the external organic matter, . When the eutrophication is extreme, all the dissolved oxygen in the water is depleted, so that all living organisms that use oxygen are killed and decayed and the water is rotten and odorous. This is a problem of the green algae phenomenon.
Several methods have been introduced to improve water quality by inhibiting the occurrence of green tides and red tides. Chemical methods include oxidizing agent spraying (quicklime, calcium hydroxide, copper sulfate, copper sulfate, etc.), flocculant (polymer flocculant, natural flocculant, etc.) Mineral coagulants, inorganic coagulants, etc.), algae removal, and loess spraying. The physical method has the disadvantage that it is possible to remove the algae immediately but it is difficult to apply to wide area and the maintenance cost is high. The chemical method is easy to spread in a wide range of water and is excellent in removing the rust, but it is possible to cause the problem of additional pollution caused by chemical substances and removal of coagulated pollutants.
Considering the economic efficiency in Korea, it mainly removes algae by spraying loess. Horticulture coalesces with algae and sinks into the spruce to remove pollutants on the surface of the water. However, submerged harmful algae may corrode over time and contaminate surrounding waters. Attempts have been made to solve the preceding problem by flocculating the flooded algae on the surface of the water, but there is a disadvantage that subsequent removal measures are necessary because the flocculent flocculants must be removed again. In addition, the raw yellow soil contains a large amount of metal impurities, which can adversely affect the ecosystem.
As a method of removing harmful algae basically from outside the country, a method of sedimentation using a loam soil and a seabed are used. It is also used as a pyrolysis method to decompose harmful algae by using heat source. However, it is difficult to cope with the problem of subsequent removal or the pollution of wide area as well as the algae removal by the application of the loess .
Many of the above-mentioned prior art patents also disclose a water quality improving agent which is a mixture of oxidizing agent, polymer flocculant, natural mineral flocculant and loess as a chemical harmful algae removing method. Therefore, a follow- Lt; / RTI >
Recently, research using hydrogen peroxide to remove harmful algae without chemical coagulants has been under way. It is known that hydrogen peroxide can be sprayed on fresh water and seawater to effectively remove harmful algae. In detail, hydrogen peroxide oxidizes harmful algae proteins, lipids and DNA, damages cells, inhibits the expression of photosynthetic genes, and destroys chlorophyll, thereby inhibiting the growth of harmful algae and further degrading them.
However, spraying equipment such as pumps is necessary to spray hydrogen peroxide, and it is not easy to spray evenly over a large area. In particular, the area where the spray is applied by the pump may adversely affect the ecosystem due to the intensive introduction of hydrogen peroxide.
It is an object of the present invention to provide a green algae removing agent capable of safely transporting hydrogen peroxide in the form of a powder in the form of powder having a green algae removing function.
Another object of the present invention is to provide a green tea remover which can be realized in powder form while having the same evaporation and diffusion effect as in the case of a liquid phase.
It is another object of the present invention to provide a soil remover which is easy to spray and can be evenly distributed throughout aquatic ecosystem.
Another object of the present invention is to provide an eco-friendly algal remover which does not generate suspended matter or residual harmful substances when added to aquatic ecosystem.
In order to solve the above problems,
One embodiment of the present invention includes a three-dimensional branched structure inorganic material and hydrogen peroxide water, which is one selected from the group consisting of fumed silica, carbon black, and combinations thereof, and the hydrogen peroxide water is added to the adjacent branches of the three- Wherein the difference in the amount of hydrogen peroxide solution evaporated from the algicide is 0 to 5 wt% / hr as compared to the liquid hydrogen peroxide having the same concentration as the number of hydrogen peroxide caught in the algicidal remover under a reduced pressure of 0.1 MPa The present invention is not limited thereto.
In this way, capturing the hydrogen peroxide water having the effect of removing the green algae in the space between the branch structures of the three-dimensional branched structure inorganic material is realized as a solid type, and at the same time, the algal removal agent having the same evaporation amount per hour as the liquid hydrogen peroxide solution can be provided.
The three-dimensional branched structure inorganic material and the hydrogen peroxide solution may be present in a weight ratio of 35:65 to 99: 1.
The algicide may be a powdery algaecide.
The angle of repose of the algicide may be in the range of 10 to 40 [deg.].
The concentration of the hydrogen peroxide solution may be 0.1 to 10 mg / L.
Another embodiment of the present invention is a method for preparing a mixture comprising mixing a three-dimensional branched structure inorganic material selected from the group consisting of fumed silica, carbon black and combinations thereof with hydrogen peroxide water to prepare a mixture, Trapping in a space between adjacent branches of the three-dimensional branched structure inorganic material, the method comprising the steps of: (a) contacting the liquid detergent with a liquid phase hydrogen peroxide solution having a concentration equal to the concentration of hydrogen peroxide captured in the algicidal remover under a reduced pressure of 0.1 MPa, Wherein the difference in amount of hydrogen peroxide water evaporation is 0 to 5 wt% / hr.
The speed of the high-speed agitation may be 50 to 500 rpm.
The agitation may be performed for 0.5 to 60 minutes.
The three-dimensional branched structure inorganic material and the hydrogen peroxide solution may be present in a weight ratio of 35:65 to 99: 1.
Thus, by producing the algicidal agent in a form in which the hydrogen peroxide is trapped in the inorganic structure of the three-dimensional branch structure, physical effects such as the evaporation rate and the diffusion rate, which are almost the same as those of the liquid phase, can be given while implementing the hydrogen peroxide solution in powder form.
The algal remover of the present invention is harmless to the aquatic ecosystem and is environmentally friendly, including hydrogen peroxide which is decomposed into water and oxygen over time and does not have a problem of further contamination by chemical substances.
In addition, the algal remover of the present invention can be provided in the form of powder while having a diffusion rate equal to the diffusion rate of the aqueous hydrogen peroxide solution.
In addition, the present invention is capable of safely transporting the hydrogen peroxide solution to the application site by capturing the hydrogen peroxide at the risk of transportation during the three-dimensional branch structure.
In addition, the algal remover of the present invention can be widely and uniformly dispersed in a powder phase, and is not concentrated at any one point, so that there is no problem in aquatic ecosystem stability.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described hereinafter. It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.
Hereinafter, the present invention will be described in detail.
Algae remover
One embodiment of the present invention includes a three-dimensional branched structure inorganic material and hydrogen peroxide water, which is one selected from the group consisting of fumed silica, carbon black, and combinations thereof, and the hydrogen peroxide water is added to the adjacent branches of the three- Wherein the difference in the amount of hydrogen peroxide solution evaporated from the algicide is 0 to 5 wt% / hr as compared to the liquid hydrogen peroxide having the same concentration as the number of hydrogen peroxide caught in the algicidal remover under a reduced pressure of 0.1 MPa The present invention is not limited thereto.
Here, the term "three-dimensional branched structure inorganic material" refers to a form in which a plurality of inorganic fine particles are gathered and extended irregularly in a space in a branch form, and these three structures are in contact with each other to form a three-dimensional networking . The shape of the branch may include a detailed branch of each branch extending from the branches forming the central portion, or may be formed of a plurality of branches without a distinct central portion, and each branch may include a branch.
A space may be provided between the branches and the branches of the inorganic material of the three-dimensional branched structure in which the basic particles are gathered, and the hydrogen peroxide may be trapped in this space. By capturing the hydrogen peroxide water in the inner space of the inorganic material, the hydrogen peroxide water can be safely transported to the application site and sprayed in the captured state, so that the concentration of the hydrogen peroxide water does not increase rapidly but spreads gradually to water, .
The three-dimensional branched structure inorganic material may be at least one selected from fumed silica and carbon black.
Fumed silica is amorphous silicon dioxide, a very light powder of white color. The average diameter of the base particles is from about several nanometers to several tens of nanometers, has a large specific surface area, and can range from 50 to 400 m 2 / G. Fumed silica is produced by hydrolysis in flame above 1000 ℃, in which chlorosilane is formed with oxygen and hydrogen. The basic particles made from flame are connected to each other due to the collision with each other in the state where the surface is still melted, so that they form a linear branch shape, which can be connected to form a three-dimensional branch structure. The size of such agglomerates may be from several tens of um to several hundreds of um.
Carbon black is a black amorphous hydrocarbon. Industrially produced by injecting a high aromatic heavy oil into a high temperature of 1600 to 2000 ° C. Carbon black also forms a linear branch structure by thermal fusion of base particles made at high temperature, which is connected by physical collision to form a three-dimensional branch structure. Similar to fumed silica, the size of such aggregates may be from several tens of um to several hundreds of um.
As described above, both of the fumed silica and the carbon black are fired to form a secondary aggregate through primary aggregation. In the primary aggregate, the primary particles are gathered to form the branch structure, and the secondary aggregate As the primary aggregates come into contact with each other, they become a three-dimensional branch structure inorganic form as described above, and can be said to be a kind of grape clusters.
Since both the fumed silica and the carbon black are inorganic substances having such a three-dimensional branched structure, the hydrogen peroxide solution can be confined in the inner space thereof, so that it can be realized as a solid stable formulation.
Further, both the fumed silica and the carbon black are environmentally friendly, can contain a relatively large amount of hydrogen peroxide in the inner space, and have excellent hydrogen peroxide capturing ability.
In particular, in the case of fumed silica, both hydrophobic and hydrophilic can be used.
When capturing hydrophilic hydrogen peroxide water in the hydrophobic fumed silica, it is possible to provide a kerosene removing agent in which the number of hydrogen peroxide is confined in the space between the branch structures of the fumed silica.
In addition, when capturing hydrophilic hydrogen peroxide water in the hydrophilic fumed silica, the physical mechanism is different from the case of mixing the inorganic material with the opposite nature and the hydrogen peroxide water. The hydrogen peroxide is supported on the surface of the branch structure itself based on the capillary phenomenon, It is possible to provide a keloid removing agent in a form that is clipped in the space between the branch structures by aggregation due to the affinity between the hydrogen peroxide number and the branch structure.
The three-dimensional branched structure inorganic material and the hydrogen peroxide water may be present in a weight ratio of 35: 65 to 99: 1.
Specifically, it can be implemented in powder form if it is present in the range of 35:65 to 99: 1, and can be implemented in gel form up to 5:95 if the content of hydrogen peroxide is greater.
The algal remover of the present invention is preferably prepared in powder form in order to uniformly spray the aqueous hydrogen peroxide solution on the aquatic ecosystem and uniform the concentration of the hydrogen peroxide solution over the sprayed area.
At this time, it was confirmed that when the inorganic material of the three-dimensional branched structure was contained in an amount of 35 wt% or more, the powder could be formed in a gel state and 5 wt% or more and less than 35 wt% could be formed in a gel state.
Therefore, the hydrogen peroxide solution can be adjusted to an appropriate amount depending on the application within the range of 35:65 to 99: 1 to provide a powdery antioxidant.
As described above, the algal remover may be in the form of a powder, which can be realized by controlling the content of inorganic matter and hydrogen peroxide in the three-dimensional branched structure. By capturing the hydrogen peroxide water in powder form and transporting it, it is easy to carry and store the hydrogen peroxide water, and it is also stored inside the inorganic structure of the three-dimensional branch structure, so that safety can be also accompanied.
In particular, the angle of repose of the algicide may be 10 to 40 °.
Here, "angle of repose" refers to the maximum inclination angle at which sediment can be deposited without falling down when deposited on a slope. The smaller the angle of repose, the smaller the adhesion force between particles is, indicating that it is more powdery.
The angle of repose of the dry sand on the basis of the powder phase is about 34 °. According to an embodiment of the present invention, the angle of repose of the algae removing agent in the powder is in the range of 10 to 40 °, Respectively.
The concentration of the hydrogen peroxide solution may be 0.1 to 10 mg / L.
If it is less than 0.1 mg / L, it is difficult to show a significant effect on the removal of green algae. Hydrogen peroxide is usually present in surface water of natural water at 1 to 30 ug / L. Is also dissolved in water, there is a risk of adversely affecting the ecosystem.
Therefore, by controlling the concentration of the hydrogen peroxide solution within the above range, it can be harmless to the aquatic ecosystem and have the effect of removing the green algae.
Method of manufacturing algal remover
Another embodiment of the present invention is a method for preparing a mixture comprising mixing a three-dimensional branched structure inorganic material selected from the group consisting of fumed silica, carbon black and combinations thereof with hydrogen peroxide water to prepare a mixture, Trapping in a space between adjacent branches of the three-dimensional branched structure inorganic material, the method comprising the steps of: (a) contacting the liquid detergent with a liquid phase hydrogen peroxide solution having a concentration equal to the concentration of hydrogen peroxide captured in the algicidal remover under a reduced pressure of 0.1 MPa, The difference in amount of hydrogen peroxide water evaporation is 0 to 5 wt% / hr.
Specifically, as a method for trapping hydrogen peroxide in a space between branches of a three-dimensional branched structure inorganic material, a mixture in which a mixture of inorganic matter and hydrogen peroxide is formed is prepared first.
When the hydrogen peroxide water and the three-dimensional branched structure inorganic matter are mixed without any treatment, the hydrogen peroxide water and the three-dimensional branch structure inorganic matter are not well dispersed, and the hydrogen peroxide water is not trapped in the space between the branch structures.
Thereafter, the mixture is stirred at a high speed in a closed space to give a high energy. Through this energy, the hydrogen peroxide water liquid is divided into fine droplets and contained in the three-dimensional branched structure inorganic material.
At this time, the stirring speed may be 50 to 500 rpm. When stirring at a speed of less than 50 rpm, the hydrogen peroxide water may have a part of the inorganic material of the three-dimensional branched structure clustering. In the case of stirring at a speed exceeding 500 rpm, the inorganic material of the three- And some of the hydrogen peroxide water splashes to the wall surface to produce a uniformly mixed algicide remover.
Therefore, when stirring is carried out at the rotational speed of the above range, energy of the most appropriate level is given, and the hydrogen peroxide can be well trapped in the inner space of the three-dimensional branched structure inorganic material, and a powdery or gel-like antioxidant is produced according to the amount of hydrogen peroxide .
In addition, the stirring is preferably performed for 0.5 to 60 minutes, which can be controlled depending on the total amount of hydrogen peroxide and the absolute amount of the inorganic structure of the three-dimensional branch structure.
However, when it exceeds 60 minutes, it is confirmed that hydrogen peroxide evaporates at least 1% or more.
The three-dimensional branched structure inorganic material and the weight ratio of 35: 65 to 99: 1.
35: 65 to 99: 1, and in the case where the content of hydrogen peroxide is more than 5: 95, the gel can be realized.
The algal remover according to the present invention is preferably prepared in powder form in order to uniformly spray the aqueous hydrogen peroxide solution on the aquatic ecosystem and uniform the concentration of the hydrogen peroxide solution over the sprayed area.
The three-dimensional branched structure inorganic material may be at least one selected from fumed silica and carbon black.
Both the fumed silica and the carbon black form a branch structure by firing and aggregation of the base particles, and these branch structures are contacted and extended to realize a three-dimensional branch structure. At this time, by stirring the mixture, the hydrogen peroxide water is caught in the space provided between the branches and the branches, and the hydrogen peroxide water can be confined in the inner space, thereby realizing a green tea remover that captures hydrogen peroxide water safely.
The phase of the algaecide can be determined according to the content ratio of the inorganic matter and the hydrogen peroxide solution in the three-dimensional branched structure. The algae-removing agent can be prepared by adjusting the amount of the algaecide in an appropriate amount depending on the application.
Hereinafter, preferred embodiments of the present invention will be described in order to facilitate understanding of the present invention. However, the following examples are provided only for the purpose of easier understanding of the present invention, and the present invention is not limited by the following examples.
1. Evaluation of the type of algae removing agent according to the mixing ratio of inorganic matter and hydrogen peroxide water
In each of Examples 1 to 2 and Comparative Example 1, a mixture in which fumed silica having a three-dimensional branched structure and hydrogen peroxide water (concentration: 2.4 mg / L) were added in the ratios shown in Table 1 were stirred at 350 rpm The appearance and condition of the algae remover were shown in Table 1 below.
The fuel composition of Comparative Example 2 was prepared by simply mixing the same materials as in Production Example 1 in the same proportions.
As shown in Table 1, Example 1 was in powder form and Example 2 was in gel form. This confirms that the hydrogen peroxide water is trapped in the space between the branch structures of the fumed silica, so that the hydrogen peroxide is not leaked apparently.
In addition, in the case of Comparative Example 1 containing more than 97% by weight of the hydrogen peroxide solution, it can be seen that even if it is produced by the same method as that of the embodiment, the internal space of the fumed silica is insufficient and is not realized as a solid shape.
In addition, it was confirmed that Comparative Example 2 containing fumed silica and hydrogen peroxide water in the same contents as in Example 1 but not in the form of a powder was produced in the form of a liquid phase in which fumed silica was dispersed in hydrogen peroxide water.
2. Evaluation of dispersibility of algicide
A green tea remover was prepared in the same manner as in Example 1 except that a yellow pigment was added to the hydrogen peroxide solution, and the process was photographed while dispersing the green tea remover in the powder.
Referring to Fig. 3, (a) is a photograph immediately after the introduction of a powdery antioxidant.
Next, (b) is a photograph of the dissolution of the algicide remover, in which the algicide remover was dispersed as a whole in the vicinity of the bottom of the solution, and the concentration of the hydrogen peroxide solution was not increased at any point but spread evenly over the entire area.
Thereafter, referring to (c), it can be seen that the aqueous hydrogen peroxide solution, that is, the aqueous phase spreads throughout the solution and is uniformly dispersed.
Therefore, when the algal remover of the present invention is used, the concentration of the hydrogen peroxide solution can be distributed evenly without floating, thereby being eco-friendly.
3. Evaluation of physical properties of algicide (amount of evaporation)
The evaporation amount of the liquid hydrogen peroxide solution (Comparative Example 3) and the algal remover (Example 1) of the present invention was confirmed under a reduced pressure of 0.1 MPa. In order to compare the evaporation amount, the amount of the algicide was 1.54 times higher than that of the hydrogen peroxide, and the concentration of the hydrogen peroxide solution was the same.
The amount of hydrogen peroxide vaporized per hour is shown in Table 2 below.
As shown in Table 2, it can be seen that the evaporation amounts per hour of Comparative Example 3 and Example 1 are almost similar.
Specifically, the difference was 3 wt% / hr in the 2 ~ 3 hours interval and 16% / hr in 1 ~ 2 hours interval.
Therefore, it was confirmed that the algicide of the present invention exhibited the same evaporation rate as that of liquid hydrogen peroxide even though it was in a powder form safely provided in inorganic matter of three-dimensional branched structure of hydrogen peroxide.
That is, the algal remover of the present invention has the advantage of providing hydrogen peroxide water in the form of a powder without chemical modification and having the same physical properties as liquid hydrogen peroxide.
