Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for purifying or activating water in, for example, lakes and marshes, rivers, groundwater, rainwater, and wastewater.

[0002]

2. Description of the Related Art As a technique for purifying sewage, for example, there is an apparatus disclosed in Japanese Patent Application Laid-Open No. 9-327695. This purification device has a magnetic treatment device that performs magnetic treatment on raw water and a filter medium that allows microorganisms useful for water purification to inhabit and performs filtration.The raw water activated by the magnetic treatment device is passed through the filter material. And then return to raw water.

[0003] In this apparatus, however, a filter is provided in front of the magnetic processor to remove visible dust from the raw water. However, since the magnetic processing is performed by itself, the effect of activating the water by the magnetic processing can be sufficiently achieved. Can not enjoy. For this reason, it is difficult to purify a large amount of raw water such as lakes and mars, which is extremely dirty.

[0004] Further, as the above-mentioned filter material, a plastic material to which a biofilm easily adheres is used, and only a physical filtering action can be expected. For this reason, it is indispensable to occasionally work to reverse the magnetically treated water to wash the filter medium.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is a main object of the present invention to sufficiently effect the magnetic treatment so that water can be efficiently treated.

[0006] Means for this is to pass the water to be treated in the reservoir through a filtration and reforming device having a filter, far-infrared radiation ceramics and natural stone to perform a filtration and reforming treatment,
It is a water treatment method in which magnetic treatment for passing the treated water subjected to the filtration reforming treatment through a magnetic field is performed in a plurality of stages, and the magnetic treatment in the plurality of stages is performed with a stronger magnetic field as the magnetic treatment in the subsequent stage is performed. And

That is, the water to be treated first passes through the filter, the far-infrared radiation ceramics, and the natural stone in an appropriate order. The order of passing the water to be treated is appropriately set according to the nature of the water to be treated and the purpose of the treatment. In addition, an appropriate filter such as a fiber filter, a wire mesh, or a ceramic filter may be used as the filter. Far-infrared radiating ceramics and natural stones are formed into granules and used by filling a large number of them. As the natural stone, an appropriate natural stone is selected according to the nature of the water to be treated and the purpose of the treatment, such as zeolite, barley stone, and sodalite.

[0008] The impurities are removed while the water to be treated passes through the filter, and the water is activated by heat absorption when passing through the far-infrared radiating ceramics. Various filtration and reforming processes are performed according to the properties of natural stone, such as adsorption and separation by a large number of pores, ion exchange, and chemical change due to eluted components.

The treated water subjected to the filtration and reforming treatment is:
It is in a state of high functionality compared to the water to be treated, which is merely physically removing dust. In this state, the water to be treated is subjected to magnetic treatment by passing through a magnetic field, so that the water to be treated is activated when the clusters (molecular populations) are subdivided into fine particles and activated.
Receives the effects of magnetic processing efficiently. In addition, the magnetic processing is performed in a plurality of stages, and the magnetic processing is performed with a stronger magnetic field as the magnetic processing is performed at a later stage.

[0010] The water to be treated is thus treated such as being purified or activated.

In the treatment of sewage such as lake water or wastewater, the water to be treated activated by the magnetic treatment is preferably returned to the storage part and / or the filtration and reforming apparatus. When the water is returned to the reservoir, the water to be treated can be circulated.
Effective treatment can be performed even on dirty water or a large amount of water. In other words, the activated water to be treated returns to the reservoir, and its activity decomposes blue water, turbidity-causing water and organic matter in soil, sterilizes common bacteria such as Escherichia coli, and produces sludge. Suppress the activity of. Then, the environment inside the storage section is gradually changed toward a desired state, and the whole of the water to be treated in the storage section can be made into viable water having a self-cleaning action. When refluxed to the filtration reforming part,
The activated water to be treated acts on the filter, the far-infrared radiation ceramics, and the natural stone, thereby decomposing the adhered dirt and restoring the function, thereby eliminating the need for cleaning and replacement.

Further, at the time of reflux to the storage section, it is preferable that the water to be treated is injected to stir the water to be treated. The injection position is determined in consideration of the water inlet and the water outlet, if any, in the reservoir. Since the storage parts such as lakes and marshes are stirred, the reaction and purification can be promoted, and the processing efficiency can be improved. In addition, since the stirring is not performed by rotating the screw or the like but by the water flow, the apparatus can be processed in an extremely natural state without increasing the size of the apparatus. For this reason, for example, water treatment is possible even in a state where fish and plants are present. The injection may be performed not only in a fixed direction but also by swinging the head.

In the treatment of water to be treated such as water from lakes and marshes, in addition to performing the treatment described above, the incoming water is subjected to a magnetic treatment by passing it through a magnetic field, and then the storage or / and / or It is good to inject into the filtration reformer. Since the water to be injected is activated by the magnetic treatment, it is possible to suppress the contamination and to further improve the treatment efficiency.

Another means is to provide a storage section for storing the water to be treated, a transfer means such as a pump for transferring the water to be treated in the storage section, and a filter and a far-infrared ray in the transfer direction of the water to be treated. A filtration and reforming device having radiant ceramics and natural stone is provided, and a plurality of magnetic treatment devices for applying a magnetic force to water to be treated that has passed through the filtration and reforming device are provided at a subsequent stage of the filtration and reforming device. Is characterized in that the latter is a water treatment system arranged with a stronger magnetic field.

That is, the water to be treated in the storage section is transferred by the transfer means, and first enters the filtration and reforming apparatus. here,
It passes through filters, far-infrared radiation ceramics, and natural stones in an appropriate order. The order of passing the water to be treated is appropriately set according to the nature of the water to be treated and the purpose of the treatment. As the natural stone, an appropriate natural stone is selected according to the nature of the water to be treated, the purpose of the treatment, and the like, such as zeolite, barley stone, and sodalite.

The impurities are removed while the water to be treated passes through the filter, and the water is activated by heat absorption when passing through the far-infrared radiating ceramics. Various filtration and reforming processes are performed according to the properties of natural stone, such as adsorption and separation by a large number of pores, ion exchange, and chemical change due to eluted components.

The water to be treated, which has passed through the filtration and reforming treatment apparatus, has a higher functionality than the water to be treated, which simply removes the dust. In this state, the apparatus enters the next multi-stage magnetic processing apparatus. Since the water to be treated is subjected to magnetic treatment by passing through a magnetic field in this magnetic treatment apparatus, it is efficiently subjected to the effect of the magnetic treatment, for example, clusters (molecular groups) are subdivided into fine particles and activated. Moreover,
Since a plurality of magnetic processing devices are provided, and the magnetic processing device in the latter stage also has a stronger magnetic field, the magnetic processing device can be effectively raised to a desired active state which is a high energy state.

It is preferable that a reflux path to the storage section and / or the filtration and reforming apparatus is formed at a stage subsequent to the magnetic processing apparatus. The water to be treated returned to the reservoir through the return channel decomposes water and turbidity, decomposes water and organic matter in the soil, sterilizes common bacteria such as Escherichia coli, and suppresses the activity of sludge. I do. Then, it is processed again.
By such a circulation, the environment in the storage section is gradually changed toward a desired state, and even in the case of highly-dirty treated water or a large amount of treated water, the entire treated water in the storage section is eventually removed. Vibrant water having a self-cleaning action can be obtained.
In addition, the water to be treated that has entered the filtration and reforming device through the reflux path is clean and has become activated as fine particles. For disassembly and function recovery,
Cleaning and replacement work can be eliminated.

Further, it is preferable to provide an injection nozzle at the end of the return path to the storage section. The injection position is determined in consideration of the water inlet and the water outlet, if any, in the reservoir. Stir reservoirs such as lakes and marshes to promote reactions and purification,
Processing efficiency can be improved. In addition, since the stirring is not performed by rotating the screw or the like but by the water flow, the apparatus can be processed in an extremely natural state without increasing the size of the apparatus. For this reason, for example, water treatment is possible even in a state where fish and plants are present. The injection may be performed not only in a fixed direction but also by swinging the head.

Further, a water supply path to another water treatment system may be formed at a stage subsequent to the magnetic treatment apparatus. For example, a pond purification treatment system, groundwater and well water improvement treatment systems, and rainwater and wastewater purification treatment systems
Alternatively, by properly connecting a plurality of types of liquid treatment systems via a water supply channel, water can be completely and effectively used, which greatly contributes to environmental conservation. The water supply channel can extend not only from the last magnetic processing device of the plurality of stages of magnetic processing devices but also from the first or intermediate magnetic processing device. In this case, if necessary, water may be supplied after passing through a magnetic processing device having a stronger magnetic field than the magnetic processing device that passes last.

In the water body treatment system, a water supply channel for discharging the treated water passing through the magnetic treatment device may be formed, and the water supply channel may be connected to an appropriate plant cultivation device. The water supply channel is formed after the last magnetic treatment device or from a reservoir containing treated water. Vibrant water of improved properties can be provided to the plants, so that good growth of the plants is obtained.

These are well-known structures, formed using permanent magnets, which subdivide and activate water clusters by passing water through a magnetic field. The first magnetic processing device 11 has a lower magnetic flux density, and the second magnetic processing device 12 has a higher magnetic flux density. In order to purify the water of the muddy ponds with floating blue water, for example, the first magnetic processing device 11 should have about 900 to 1500 gauss and the second magnetic processing device 12 should have about 4500 to 500 gauss.
What is necessary is just to use about 5000 Gauss.

For example, in the case of a rectangular pond, the processing tank 4 is installed at the center as shown in FIG.
May be arranged at two points on the diagonal line so that the directions are the same.

If there is water (refilling water) entering the lake 3, the water entering the lake 3 is appropriately filtered and then passed through the same magnetic treatment device 18 as described above. It is injected into the first reforming tank 8 and the like. Rehydration is the first
As long as the magnetic processing is performed to the extent of the magnetic processing performed by the magnetic processing apparatus 11, the passing magnetic processing apparatus 18 has a stronger magnetic field than the first magnetic processing apparatus 11, such as the above-described second magnetic processing apparatus 12. If the magnetic treatment is not performed at all, it is preferable to pass through a plurality of stages of magnetic processing devices having different magnetic field strengths.

In the water treatment system 2 configured as described above, water purification is performed as follows. The processing can be performed while animals and plants remain.

Thereafter, further magnetic processing is performed by the second magnetic processing device 12 having a stronger magnetic field than the first magnetic processing device 11, and water clusters are subdivided into fine particles and activated to a desired active state.

The activated purified water is supplied to the injection nozzle 1
7 and is injected into the lake 3. The injected purified water stirs the water 1 in the lake 3 and spreads over the whole. Then, by the action of active oxygen and microorganisms, water and organic substances in the lake 3 are decomposed, and bacteria such as Escherichia coli are sterilized. Pollution of water and mud will be suppressed. And
The used water is again filtered and reformed 6 and the first floor treatment 1
First, it is discharged into the lake 3 through the second magnetic processing device 12.

By the circulation of the purified water, the transparency of the water is increased, the pH value and the number of bacteria are stabilized, and the water becomes gradually good.

In this process, the vigorous water released again enters the filtration reformer 6, so that the filter, far-infrared radiation ceramics, and natural stone are also subjected to the activated water. . That is, decomposition of attached dirt, recovery of functions, and the like are performed. For this reason, after purifying to some extent, cleaning or replacement of the filter or the like becomes unnecessary.
