Description

Safty type system for purifying the water without using any chemical agent}

[Field of Invention]

The present invention relates to a high-purity water purification method that can produce safer drinking water than the present by improving the water purification process of the constant water with a new treatment method.

More specifically, it is a new water purification method that does not require the use of conventional chemicals for water purification, and in particular, by maximizing the use rate of the sterilizing power of ozone, it is possible to realistically enable an economical low-cost ozone disinfection method and a carcinogenic substance due to chlorine disinfection ( THM) The present invention relates to a method for safe advanced water treatment that can solve the generation problem.

Background of the Invention

Since the existence of mankind, the water supply problem would have been a matter of quality and quantitative security, but in modern countries, quantitative procurement has been the first priority in accordance with industrialization and population concentration. The problem became more serious.

The more polluted water sources become, the more complicated the water purification process is and the more chemicals are used to introduce different artificial risks.

That is, before the source of water was contaminated, safe living water could be produced and supplied by the following simple water purification process.

However, as the pollution of raw water became more severe, it changed to the following water purification method in which various kinds of chemicals were put into a complicated process.

In both processes, chlorine disinfection is carried out, but in the raw water contaminated process, residual chlorine and organic matter react to produce carcinogen called Tri Halogen Methan (THM), which was not a concern in the chlorine disinfection method of the raw water. There is a new danger. In addition, as a type of flocculant, inexpensive aluminum sulfate (Al ₂ So ₄ ) is mainly used, and as a result, Al remains as an obstacle to the nervous system and thus poses another danger as drinking water. The problem of water pollution is not easily solved in a short time due to industrialization. Moreover, it is not easy to solve the problem of water purification process in regions and countries where economic power is insufficient.

Ozone (O ₃ ) is easily separated to generate generator oxygen, and the oxidizing power of the generator oxygen is about 5 to 6 times stronger than chlorine, leaving no smell or color and leaving no chemical properties.

The new treatment process of the constant safety type purified water treatment system without the chemical of the present invention is schematically performed as follows.

In other words, the treatment process of this method is significantly different from the treatment process mainly for chemical treatment.

First, the primary filtration is a countercurrent slow sand filter paper, which is installed in front of the sedimentation basin.

Secondly, disinfection is done only by ozone, minimizing the ozone (unused ions).

Third, sterilization by ozone is also performed in the impingement well, and the ozone is reused.

Fourth, the activated carbon adsorption process is operated as a safety device that operates only when necessary as a BY-PASS process. In other words, THM is not produced, so it is not necessary to remove the adsorption, and since odors are removed during sterilization by ozone, unlike the case of chlorine disinfection, it is necessary to operate at all times.

Fifth, the use of flocculants, flocculating aids, chlorine, PH regulators, powdered activated carbon and the like will not be used.

Sixth, the nitrogen components (NH ₄ , NO ₂ , NO ₃ ) and phosphorus components in water are removed using water plants.

[Objective of the invention]

It is an object of the present invention that water is used as drinking water for humans, livestock, and other animals, and the pollution is gradually accelerated, and it is difficult to recover it to the pre-industrial state of human civilization. This is to solve such risks as drinking water because of overdose of carcinogens, and it is more expensive than ozone water purification method even in countries that already carry out ozone sterilization by spreading technology that maximizes ozone utilization. It is to improve human health by supplying economical and safe tap water by making cheap ozone purification method available.

In addition, the conventional water purification method has a difficulty in removing nitrogen compounds such as NO ₃ contained in raw water and causing cyanosis in humans, but it is also possible to remove these components using water plants. Such a method of removing nutrients using the myelin sheath is already developed and applied for sewage / wastewater treatment by those skilled in the art, but the present technology has been developed for water purification treatment of constant water so that it can be easily removed in the related art. This is to remove as much of the nutrients that were not present in a safe and non-hazardous way as much as possible.

The above and other objects can be realized by the present invention described below.

Summary of the Invention

Safe type purified water treatment system without the chemicals of the present invention is the raw water inlet pipe (1) or the landing well (2) for collecting the raw water and the pump (3) and the transfer pipe (4) for transferring the raw water, And an upstream slow slow filter (5) for firstly purifying the transferred raw water, a natural settler (6), and a downflow slow slow filter (7) for secondarily filtering the water transferred from the natural settler (6). , Ozone sterilizing water for ozone sterilization of secondary filtered water (10), ozone generation and storage tank (11), pumping tank (12) and pump (13) for temporarily storing ozone sterilized water, and sterilized water again Activated carbon adsorption tank 14 for altitude purification, storage tank 15 for storing the final treated water, feed pump 17 and supply pipe 18, and activated carbon adsorption tank 14 depending on the purified water It is composed of a bypass pipe 16 that can be transferred directly to the reservoir 15 without.

On the other hand, each of the lower side of the upflow slow slow filter (5) and the natural settler (6) and the upper back of the slow flow slow filter (7) and the activated carbon adsorption tank (14), a backwash conveying pipe for transporting backwash wastewater during backwashing 19 are respectively installed, and a wastewater storage tank 20 for storing backwash wastewater is installed.

The high-efficiency ozone contact 10 may be composed of one paper or two or more papers in consideration of treatment capacity or ozone utilization efficiency, and may be arranged in various forms as shown in FIG. In addition, underwater aeration device (10-5, 10-8, 10-10, 10-12) and ozone air suction pipe (10-6a, 10) to inhale ozone into the contact area and abandon the ozone air into small bubbles in the lower part of the contact area. -6b, 10-6c, 10-6d) and ozone transfer tubes (10-14a, 10-14b, 10-14c, 10-14d), and associated ozone transfer tubes (10-7, 10-9, 10-11), an ozone detector (10-15) and an ozone treatment apparatus (10-17) capable of detecting the final ozone zone.

Therefore, in the constant type safety water purification system without the chemicals of the present invention, chlorine used to prevent the shelling of fish and shellfish by using ozone for disinfection of the landing well may not be used, and precipitation does not occur well in natural sedimentation basins. Although flocculents were used to quickly settle the suspended solids and algae, the upstream slow-flow filter paper (5) was placed in front of the sedimentation basin instead of the method of injecting the flocculant so that the suspended solids and algae could be filtered without chemicals. do.

The upflow type slow yarn filter paper 5 has a distribution box 5-2 and a large gravel layer 5-3 formed on the lower end thereof, and a heavy gravel layer 5-4, an electron brown layer 5-5, and the upper portion gradually. It consists of royal sand layer (5-6), medium sand layer (5-7) and fine sand layer (5-8), and the treated water is filtered while moving gradually from the bottom to the top, so that the amount of suppression of turbidity and algae increases and stays even during backwashing. As water flows downward, desorption of inhibitors is easily achieved. As such, backwashing is easy and a large amount of foreign matter can be suppressed, so that a rapid precipitation using a flocculant can be substituted.

Usually, the sand layer of the slow yarn filter paper has microbes inhabited as the filtration time lasts, and it is difficult to remove the lumps by forming agglomerates with each other. The sand layer (5-6,5-7,5-8) of the ozone to the immersion well (2) by the sterilization of the microorganisms do not live in the filtrate, so this obstacle is greatly reduced, so it is easy to operate.

In addition, in the uppermost layer of fine sand (5-8) of the filtrating layer, the plant is planted with 5-5-12 raw water to reverse the roots of the plant (5-13) to absorb and remove nitrogen compounds.

Therefore, the primary filtrate from which the main foreign matters of the raw water are removed is able to remove the suspended matter remaining only by natural precipitation for a predetermined time in the natural precipitater (6).

Even on the surface of the natural sedimentation basin (6) water vegetation plants (frog rice, hyacinth, breoxam, etc.) is planted to absorb nitrogen compounds or denitrification.

The precipitated water is again treated with clearer water in the downflow slow sand filter paper (7), which is more filtration capable than the upflow filtration method, and the remaining organic matter is absorbed and decomposed by the microorganisms in the filtrate.

The treated water that has undergone the above process still needs chemical disinfection such as odor or phenol and various microorganisms newly introduced in the previous treatment, so it needs to be sterilized by powerful oxidizing agent. Will be used.

Ozone is in a gaseous state and is separated into oxygen molecules (O ₂ ) and generator oxygen (O) in water so that the generator oxygen reacts with the oxidized substance.

This ozone contact sterilization method has been used by conventional contact methods as shown in Figures 3A, 3B, 3C, and 3D, but it was not possible to completely dissolve the ozone introduced by these methods alone. Therefore, a large amount of ozone is not used for the purpose, but is discharged into the air as an ozone zone. Such leakage of ozone into the air can cause photochemical smog, which is not only harmful to the human body but also rapidly corrodes steel products that are easily oxidized. Follow-up facilities for treating the ozone in various ways should be followed.

Although ozone is generated in various ways, it is commercialized by using air or produced oxygen and producing it through high-voltage discharge, and it has to go through various processes such as compression cooling and filtration of air used before the discharge process. This is expensive. Therefore, the high-efficiency ozone contact point 10 is a ozone recirculation method in which the utilization rate of the supplied ozone can be maximized, and the final ozone amount can be minimized by allowing the process to be composed of a plurality of series processes if necessary. will be.

The treated water sterilized and oxidized in the high-efficiency ozone contact point 10 can be supplied immediately as a constant according to the state of the raw water. However, when the state of the constant water is deteriorated and there are many residual substances to be oxidized, activated carbon is used as the final process. The adsorption tank 14 is then supplied again after high-performance adsorption filtration.

Therefore, it is possible to perform highly purified water to remove nitrogen compounds without using various chemicals that have been introduced in the conventional water treatment method, and in particular, it is possible to economically operate the high treatment cost by maximizing the utilization rate of ozone. .

Detailed Description of the Invention

The constant type safe water treatment system without chemicals of the present invention consists of a novel treatment process and ozone sterilization method as shown in Figure 1. The upflow slow slow filter (5) in this treatment process is located in the process in front of the natural settler (6) and is composed of a structure as shown in Figure 2. The high-efficiency ozone contact paper 10 of FIG. 1 has a structure as shown in FIG. 4, and maximizes the ozone utilization rate, or when the treatment capacity is large, is configured in series as shown in FIG. Such multiple ozone contacts can be arranged in the form shown in Figure 7. In addition, when the underwater aerators (10-5, 8, 10, 12) as shown in Figs. 4 and 6 are not suitable, such as when the landing well (2) or the processing capacity is small, an external blower (40- 1,2,3,4) can be used.

Meanwhile, as shown in Figs. 4, 5, 6, and 8, the ozone treatment apparatus 10-17 is installed so that a small amount of ozone is not discharged to the atmosphere and is subjected to the final treatment.

As a method to prevent chemicals from being applied in a safe type purified water treatment system without chemicals of the present invention, firstly, ozone can be used in an efficient manner instead of chlorine for suppressing fish and shellfish habitat of the tapping well (2). Secondly, as raw water is highly contaminated with turbidity, algae, organics, etc., if it is filtered, the filtrate is blocked and the algae and turbidity are not easily precipitated by spontaneous sedimentation. In the present invention, by pretreatment with the upstream slow slow filter (5), it is possible to replace the rapid precipitation by flocculation chemicals as a large amount of suspended matters, algae, organics, etc. is suppressed and backwashing is easy.

Therefore, the sedimentation method of the sedimentation basin, which is the next process, can be configured as a natural sedimentation basin 6 that does not use chemicals, in which the remaining sedimentary suspended matter is precipitated and removed.

The precipitated water is filtered in a downflow slow yarn filter paper (7) which has better filtration adsorption properties of fine suspended matter and organic matter than the upstream slow slow filtration method, thereby avoiding the use of coagulant aids such as polymer materials used in the rapid sand filtration method. .

Third, water that has gone through the previous treatment process has strong oxidizing power because organic matter, turbidity, algae, etc. may be removed, and bacteria, odors, and other chemicals in raw water not removed in the previous process may remain. The high-efficiency ozone contact method of the present invention continuously solves the ozone in order to solve the economic problem that has been dependent on chlorine disinfection due to the problem of high production cost of ozone and low utilization rate of ozone for oxidation and sterilization with ozone. It consists of a highly efficient ozone contact paper 10 for recycling contact.

Such sterilized and oxidized water is supplied after high adsorption filtration in activated carbon adsorption tank 14 as a final process when there are a lot of new oxidative residues depending on the contaminant and degree of raw water. Will be supplied.

Fourth, nitrogen compounds (NO ₃ , NO ₂ , NH ₄ ) in the raw water components are selectively absorbed by using water plants suitable for the present high water purification process, or removed in parallel with denitrification.

Hereinafter, one preferred embodiment of a safe type water treatment system without introducing a chemical according to the present invention will be described in detail with reference to the accompanying drawings.

First, Figure 3 shows an example of a contact method for increasing the contact efficiency of ozone in the conventional sterilization and sterilization method using ozone. Fig. 3A is a turbine agitated contact method in which the ozonated air is injected into the bottom of the water tank by rotating the water by the turbine rotational force to mix the ozonated air with water. The remaining ozone used as a contact is discharged to the ozone transfer pipe 33.

3B is a radial contact method, when ozonated air is injected into the bottom of the tank through a pipe, the water is vortexed by the water pressure of the water injected by the discharge pressure of the pump, and the water is simultaneously inhaled to make contact with the ozone gas. The remaining ozone is released into the ozone zone.

Fig. 3C shows that ozoneized air at the bottom of the tank rises as a small ozone bubble from the disk plate through the pipe in contact with the water diffuser, and the remaining ozone is discharged into the ozone zone.

3D is an injector contact method that installs an injector in the water transfer pipe and absorbs ozone air inside the injector where the partial vacuum is made by the pressure of the pump to make rapid contact with water. It is discharged to the ozone from the tank installed at the end.

Such a conventional method has a problem that it is difficult to completely eliminate or minimize the ozone zone. Recently, the method of reusing the ozone in Fig. 3D to the injector supplying ozone has been proposed. Since the injector method is insufficient compared to other methods in terms of contact efficiency, many parallels are required to process a large amount of water in a short time. Many injectors are installed in the pipelines, and this process is again cumbersome in series.

Therefore, there is a need to maximize ozone utilization by the new high efficiency ozone contact method.

1, 2 and 4 to 9 is a view showing for explaining the safety-type purified water treatment system does not add a chemical according to the present invention.

The system of the present invention can replace the disinfection by chlorine by economical ozone disinfection method by maximizing the utilization rate of ozone, and by placing the upflow slow slow filter (5) in front of the sedimentation basin for chemical coagulation and sedimentation. You can not use it. As shown in FIG. 1, the raw water flowing into the watering well (2) is inhabited by more organic matters, and these fish and shellfish are prevented from being inhabited since these fish and shellfish may cause blockage of the pipe and the hobby, pathogens, and dicytobacteria. The system of the present invention supplies ozone (O ₃ ) to the bottom of the impingement well with an ozone supply pipe (9) instead of chlorine sterilization, and sterilizes by contacting water with an acid pipe.

The remaining ozone is made in contact with the water layer, and the remaining ozone passes through the ozone transfer pipe (10-14) and is re-sucked back by the aeration apparatus (10-5) as much as the amount of regulating the reuse capacity in the control valve (10-20). A small amount of ozone is also used in contact with water, and the aeration system (10-6a, 6b, 6c, 6d) or ozone recirculation, which is an ozone supply device of the high-efficiency ozone contact sheet (10) through the ozone transfer pipe (8). It is connected to the suction pipe side of the external blower (40-1, 2, 3, 4) and reused.

When the depth of the impingement well is relatively small, only a very small amount of ozone is recycled in the impingement well by the external blower 40-1 for the impingement well as shown in FIG. It is transferred to and reused. However, when the distance between the impingement well 2 and the high-efficiency ozone contact paper 10 is too long, and the reuse pipe facility is large and there is no economic value of reuse, a very small amount of ozone is treated by the ozone treatment apparatus 10-17.

The ozone supply and recycle flow in FIG. 5 is made on the same principle as in FIG. However, the starter (2) is usually made of more than one except for a very small simple water purification facility, so the effective recycling and use method of ozone in a number of starter is made as shown in FIG.

Water sterilized first by ozone in the impingement well (2) is introduced into the lower portion of the upflow slow yarn filter paper (5) by the transfer pump (3) and has a lower distribution box (5-2) as shown in FIG. It is evenly distributed from the top to the fine gravel layer (5-3) to the fine filtration layer (5-8) to the final filtration layer usually rises at a filtration speed of 10 m or less per day, preferably at a slow speed of 4 to 5 m per day. It rises and is filtered.

At this time, nitrogen compounds (NO ₃ , NO ₂ ), which are nutrients which are not removed by the slow yarn filtration, are absorbed and removed by countercurrent to the roots (5-13) of the grass planted in the filtrate. Horsegrass is not toxic and has a carbon assimilation effect in the water, releasing abundant oxygen into the water. Especially, black horses have thin straight roots that do not have a large number of roots and do not have thread like branches. It is small and does not confuse the salvage. In addition, different growth cycles are used throughout the year, which can be used to purify the upstream slow slow filter paper (5-8). In a few seconds with optimal conditions.

However, in the winter, when the growth of plants is slowing down or the company's growth is not expected, such effects are not expected or expected. Therefore, by using the thermal insulation transparent house 50 as shown in FIG. 9 and the direct and indirect radiation of the sun, fossil fuel is not used. Can reduce usage.

On the other hand, the upflow slow slow filter (5), unlike the downflow type in the configuration of the filter media can retain a large amount of foreign matter, and the foreign material detained in the lower filter layer is moved to the lower portion of the filter layer and the upper layer in the backwashing step Easily detached and stored in the wastewater storage tank 20 via the backwash water transfer pipe 19, the normal filtration process is in progress again when the backwashing operation is finished.

Therefore, the first upstream filtered water is transferred to the natural sedimentation basin 6, which is the next process, to precipitate the remaining suspended matter. In this process, are removed absorb still remaining NO ₃ components by planting surface format plants (21), from NO ₃ component can not plant is absorbed is discharged to the N ₂ gas in the NOx removal by the NOx removal reaction microorganism air Removal takes place.

This nitrification and dedusting reaction is due to the nature of the myelin sheath releases oxygen in the water in the process of the previous step, the nitrification reaction is carried out. In the natural sedimentation basin (6) while the water plants (21) cover the water surface again to dissolve the oxygen again As the oxygen is consumed by the aerobic microorganisms in the sedimentation basin and gradually progresses to anoxic state, the denitrification reaction is performed by the denitrification reaction microorganisms.

Therefore, the water-based potted plants 21 used can increase the denitrification effect by mixing frog rice, which is a plant that can completely cover the water surface, and the frog rice and fast growing hyacinth or broxam.

The plants of the natural sedimentation basin (6) are also the same in winter, so if you install and operate the thermal insulation and solar radiation using devices as shown in Figure 9 can be expected in the winter. The lower sediment of the natural sedimentation basin 6 is collected in one place by a collecting device and stored in the wastewater storage tank 20 through the sediment transport pipe 19. The naturally precipitated water is again flowed evenly to the upper portion of the downflow slow filter paper (7) through the filter layer and the support layer from the upper layer to the lower layer is collected in the collecting block and then transferred to the next process.

Filtration proceeds and foreign matter accumulated on the surface of the filtrate is separated from the filtrate by the upstream backwash operation, and stored in the wastewater storage tank 20 through the backwash wastewater transport pipe 19, and the treated water is the highly efficient ozone contact paper 10 of the following process. Ozone oxidation and sterilization takes place.

The high-efficiency ozone contact paper 10 of the present invention has a structure as shown in FIG. 6, and one or more underwater aeration devices 10-5, 8, 10, and 12 as a method of minimizing the air discharge of the ozone zone. It has an external blower 40-1, 2, 3, 4 as shown in FIG. 8 and a plurality of contact tanks and piping structures as shown in FIGS. 6 and 8, and can be arranged in various forms as shown in FIG. Applicable to both low doses.

That is, the water treated in the previous process is introduced into the transfer pipe (9) and is transferred in a zigzag up and down from the primary high efficiency ozone contact paper (10-1) to the final high efficiency ozone contact paper (10-4). On the other hand, the flow of ozone flows from the ozone generating and storage tank 11 into the suction pipe 10-6a of the underwater aeration apparatus 10-5, and the water in the state of abrupt vortex at the bottom of the high efficiency ozone contact paper 10-1. Contact with the upper depth and then out of the contact through the ozone transfer pipe (10-14a), some of which (about 70%) is back to the suction pipe (10-6a) of the aeration apparatus (10-5) The remaining portion (about 30%) is re-suctioned and flows into the suction pipe 10-6b of the underwater aeration apparatus 10-8 installed in the next high efficiency ozone contact paper 10-2, thereby contacting the paper 10-2. ) After being used in the depth layer in contact with the water of rapid vortex state at the bottom, the ozone comes out of the contact point 10-2 through the conveying pipe 10-14b, and part (70%) of the underwater aeration device (10) Re-suction into the suction pipe (10-6b) of -8) and the remaining part (about 30%) is installed inside the next high efficiency ozone contact paper (10-3) After being introduced into the suction pipe 10-6c of the device 10-10 and being used in the water depth layer at the bottom of the contact paper 10-3, it is used in the water depth layer and then through the ozone transfer pipe 10-14c. Out of the contact paper 10-3, some of them (70%) are re-absorbed into the suction pipe (10-6c) of the underwater aeration device (10-10) and the other part (about 30%) is the next high efficiency ozone. It is introduced into the suction pipe (10-6d) of the underwater aeration apparatus (10-12) installed inside the contact sheet (10-4) and is used in the depth layer by contacting water in a sudden vortex state at the bottom of the contact sheet (10-4) After the ozone detector (10-15) is detected by the ozone detector (10-15, 21) out of the contact point (10-4) through the ozone transfer pipe (10-14d). ) Is closed at the same time and is re-introduced into the first contact sheet (10-1) to go through the previous repeated contact process. If no electronic valve and the degree (10 to 16) is opened it is finished the final step in the paper times the ozone contact through the ozone treatment unit (10-17).

Such a high-efficiency ozone contact method is particularly suitable for large-capacity water treatment, and can be installed in series or in parallel in various forms as shown in FIG. 7, such as a small-capacity water treatment plant or a landing vessel (2) which should not have a sudden vortex of water. In this situation, it is possible to maximize the use efficiency through repeated ozone contact by the external blowers 40-1, 2, 3, and 4 as shown in FIG. 8, and the water flow and the ozone flow method are as shown in FIG.

When the ozone used in the high-efficiency ozone contact sheet 10 is operated at a high concentration of ozone so that the ozone used in the high-temperature ozone is discharged into the ozone zone for a certain concentration or higher for sterilization and oxidation purposes, the ozone is activated as shown in FIG. Oxidation detained in the pores of activated carbon by installing a gas-liquid contact injector (10-19) in the middle of the raw water transport pipe flowing into the adsorption tank (14) and introducing an ozone into the injector (10-19) for final reuse. Possible residual foreign matter will be oxidized.

On the other hand, water treated by high-efficiency ozone contacts (10-1, 2, 3, 4) is water sterilized and oxidized by bacteria, odors, and other oxidizable chemicals. If the raw water condition is bad, after the final adsorption treatment in the activated carbon adsorption tank 14 is stored in the reservoir 15 is supplied. In addition, all facilities that come into contact with ozone in a constant type safety treatment system without chemicals of the present invention are constructed of a material that does not corrode under the strong oxidizing power of ozone, or the contact surface is treated with various coating agents having the same performance. This prevents corrosion.

According to the safe type purified water treatment system without the chemicals according to the present invention, the pollution of the water source is increased according to the industrialization, it is possible to inject the chemicals inevitably used, and the raw water during sterilization by chlorine Although there is a risk of producing carcinogenic substances (THM) by the reaction of organic substances and residual chlorine in the area, the low economic level and the low economic level have depended on chlorine disinfection. By using the high-efficiency ozone contact method of the present invention that maximizes the use efficiency of ozone, it is possible to apply the sterilization and oxidation method by ozone at low cost, and when the nitrogen-based nutrients remain due to pollution of the water source, Although it was difficult to effectively remove these components in the method, the present invention is not toxic and purifies The removal process can be effectively carried out by using the plants that are easy to plant without any problems in the process.

These plants have good effects in the summer months, but growth slows due to temperature decreases in winter, and it is difficult to expect treatment effects.However, they use no fossil energy or consume more energy by effectively using the sun's radiant heat as energy. It will be able to reduce and keep some functions even in winter. On the other hand, in the safe type purified water treatment system without the chemicals of the present invention, the upflow slow slow filter (5) and the downflow slow filter (7) occupy a large amount of required sites, so the area where the required sites are insufficient. In FIG. 10 and FIG. 11, the upflow slow slow filter 5 and the downflow slow filter 7 may be installed in two or more layers, respectively, and operated in parallel, thereby securing a required plane. In this case, if plants are to be planted in the lower layer 5A of the upflow slow slow filter paper 5, water-resistant fluorescent lamps are installed on the ceiling of the lower layer 5A, or the growth of the myelin sheaths is transferred to the solar tube line by the optical fiber 5B. Can be maintained. Horseweed is a herb that grows under the surface of the water, so it grows at a lower level than other plants, so it is possible to plant such underground layers.

Therefore, it is possible to realize safe water purification method as drinking water and contribute to human health welfare.
