Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for activating water, a method for purifying a closed lake and a device therefor.

[0002]

[Prior Art] Lake Suwa in Nagano Prefecture and Inba Swamp in Chiba Prefecture
Pollution in closed lakes is a problem. Closed lakes have a small amount of dissolved oxygen due to the retention of water, which kills or kills aquatic plants and animals, and is contaminated by the carcasses. In addition, wastewater from surrounding factories or miscellaneous wastewater from ordinary households flows in, and nitrogen, phosphorus, etc. increase and become eutrophication, which causes abnormal growth of microorganisms, which further reduces dissolved oxygen and pollution. proceed. In other words, since the natural purification capacity cannot keep up with the pollution source, the progress of pollution will be followed. In closed lakes and marshes, the water exchange is slow and the water stays as described above, so the amount of oxygen trapped in the air is extremely small compared to natural flowing water, which reduces the natural purification capacity. It is a factor. Therefore, in some cases, air is pumped into the lake water to increase the amount of dissolved oxygen.

[0003]

However, it is not possible to supply a sufficient amount of oxygen to the whole lake water by pumping air, and the effect of purifying the sewage is not improved. In Lake Suwa and other areas, the progress of pollution is becoming less than it was in the past due to the regulation of factory wastewater and the installation of septic tanks in ordinary households, but the current status is that active purification work is rarely done.

Therefore, the present invention has been made to solve the above problems, and an object thereof is a method of activating water and purification of lake water that can lead lake water to a purification cycle. A method and apparatus therefor are provided.

[0005]

The present invention has the following constitution in order to achieve the above object. That is, the method of the present invention is characterized in that the water to be treated is made to flow in a pipe in which a magnetic field is formed by a magnet. In addition, a pipe in which lake water is sucked by a pump to flow into a delivery pipe to mix the lake water in the delivery pipe with external air, and the lake water mixed with the external air has a magnetic field formed by a magnet inside. The feature is that after it flows through the inside, it is returned to the lake by a return pipe. In the lake water purification device according to the present invention, a pump for sucking and delivering lake water,
A delivery pipe for flowing the lake water from the pump, a nozzle portion provided at the tip of the delivery pipe and ejecting the lake water as a jet by being narrowed to a diameter smaller than the diameter of the delivery pipe, and the jet water from the nozzle portion Flow jet pipe, an air supply unit for supplying external air to the jet water of the jet pipe, a magnet for creating a magnetic field in the jet pipe, and a return pipe for returning the lake water discharged from the jet pipe to the lake. It is characterized by having and.

[0006]

[Function] By passing water in a magnetic field in the form of a jet, the activation of water was achieved, although the reason is not clear. The purifying action of lake water is considered as follows. By pumping up the lake water and returning it, it is possible to create a flow of water, and in the middle of that, we made it possible to mix the external air, and to let the water mixed with the external air pass through the magnetic field. The amount of dissolved oxygen can be increased, the growth of microorganisms causes the decomposition, denitrification, and dephosphorization of organic substances, and the electrostatic breakdown of colloidal particles causes contamination sources such as clay, iron, manganese, silicic acid, and hedoro. Can be decomposed and settled, and the lake water can be guided to the purification cycle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a cross-sectional explanatory view showing a part of the purification device 10. Reference numeral 12 is a delivery pipe, which is formed to have a diameter of about 5 cm in the embodiment. Lake water is pumped to the delivery pipe 12 by a pump 14 (FIG. 2). The diameter of the delivery pipe is narrowed to the tip of the delivery pipe 12, and a nozzle portion 16 formed to have a diameter of about 3 cm is provided. At the nozzle portion 16, the lake water in the delivery pipe 12 is accelerated, and the jet pipe 1 having a diameter of about 5 cm provided at the tip of the nozzle portion 16.
It is ejected at high speed during 8th. The nozzle part 16 is the jet pipe 1
8 It has entered the rear end. Reference numeral 20 denotes an external air introduction pipe provided at the rear end of the jet pipe 18, which communicates the inside of the rear end of the jet pipe 18 with the outside air. Since the lake water is jetted from the nozzle portion 16 at high speed, the inside of the jet pipe 18 near the nozzle portion 16 has a negative pressure, and therefore the external air is introduced from the external air introduction pipe 20 into the jet pipe 18. The tip end side of the jet pipe 18 is formed in a large diameter portion 22 having a diameter of about 10 cm. In the large-diameter portion 22, five ring-shaped permanent magnets 24 made of rare earth magnets are arranged at a predetermined interval. In the embodiment, the permanent magnet 24 is formed in a ring shape having a thickness of about 1.5 cm, an outer diameter of about 10 cm, and an inner diameter of about 5 cm.
A cm iron plate 25 was interposed and fixedly arranged. Permanent magnet 2
The arrangement of No. 4 is preferably arranged so that the magnetic poles are in the same direction. In the above-mentioned permanent magnet made of a rare earth magnet, a magnetic field strength of about 5000 gauss on the inner wall surface of the ring and about 2000 to 2500 gauss on the central axis portion of the ring is obtained. It is formed. A return pipe 26 is attached to the large diameter portion 22 with a fixture 28.
The lake water in the jet pipe 18 is returned to the lake.

With the above-mentioned structure, the lake water fed into the delivery pipe 12 by the pump 14 is accelerated by the nozzle portion 16 and jetted out into the jet pipe 18 at a high speed. A negative pressure is generated in the rear end portion, and the external air is introduced from the external air introduction pipe 20 into the jet pipe 1.
8 is spontaneously flown into the jet pipe 8, is jetted out from the nozzle portion 16 at high speed, and is mixed into the jetted water which is turbulent in the jet pipe 18. The large-diameter portion 22 is the spouted water containing a large amount of this air.
While flowing in the ring-shaped permanent magnet 24 disposed inside, the following action is exerted by the magnetic field of the permanent magnet. First of all, the turbidity component in lake water is mainly made of colloidal clay, but the colloidal particles are negatively charged, repel each other and float, and turbidity is caused by the difficulty of sedimentation. By flowing this in the magnetic field, the negative charge is destroyed, which makes it easier for the particles to aggregate and is returned to the lake and settles. Similarly, the charge of ionized substances such as iron ions and manganese ions is destroyed, and sedimentation easily occurs.

Further, the jetted water flowing in the large-diameter portion 22 has a ring-shaped permanent magnet 2 arranged at a predetermined interval.
It is considered that the water molecules, which collide with No. 4 and become a turbulent flow and stay for a long time and become macromolecules, are physically finely broken. By making the water molecules finer in this way, the force of hugging inorganic substances in water becomes weaker, and the crystalline or amorphous silicic acid content that is precipitated by magnetic force precipitates as sand, and the organic matter It is considered that the part is decomposed and turned into sand. When water crosses a magnetic field, the influence on the water increases in proportion to the strength of the magnetic field and the speed at which it crosses. Water is highly polar iron under the influence of magnetic field,
It is considered that manganese, silicon, etc. are deposited and oxygen having low polarity is dissolved. Furthermore, since the jetted water collides with the ring-shaped permanent magnet 24 to cause a mixing action, a large amount of external air introduced from the external air introduction pipe 20 is dissolved in the jetted water. By increasing the amount of dissolved oxygen in this way, microorganisms proliferate and a purifying function of decomposing organic substances functions. Of course, the purifying action does not continue unless oxygen is continuously supplied in the closed lake, but the purifying action continues because oxygen is continuously supplied by the purifying device. Further, when the amount of dissolved oxygen increases, a denitrification function occurs. That is, nitrogen, which is chemically less ammoniacal, is exposed to dissolved oxygen and oxidized by nitrifying bacteria to form nitrate nitrogen.
This nitrate nitrogen touches the anaerobic part that is the dead water layer in the lake water, is denitrified by the denitrifying bacteria that live in the anaerobic part, and is released into the air. Further, the phosphorus component can be combined with iron ions existing in the anaerobic part and precipitated as iron phosphate. As described above, by removing the silicic acid which is the skeleton together with the ammonia nitrogen and the phosphorus components which are eutrophication components, the generation of algae can be prevented.

In the above-described embodiment, the external air is allowed to naturally flow from the external air introducing pipe 20 by the negative pressure in the vicinity of the nozzle portion 16, but it may be forcibly mixed by the pump. The permanent magnet 24 may be one or plural. Further, the direction of the magnetic pole is not particularly limited to the above. Instead of using a permanent magnet, an electromagnet using a commercial power source may be attached to the outer circumference of the jet pipe 18 to generate a magnetic field inside the jet pipe 18. It goes without saying that a plurality of the above-mentioned purification devices are appropriately arranged depending on the size of the lake.
Although the jet water is returned directly to the lake by the return pipe 26 in the above-mentioned embodiment, it may be returned to the lake after it is once stored in the settling tank or settling tank for precipitation.

Further, the same device as described above can be used to activate tap water, for example. In this case, the tap of the water supply can be used as it is as the delivery pipe 12.
That is, as shown in FIG. 3, the throttle 32 may be attached to the faucet 30 and the jet pipe 18 may be attached.
In the illustrated example, the individual permanent magnets 34 have different magnetic poles opposed to each other to form a positive alternating magnetic field. The external air introduction pipe 20
It doesn't have to be. In this way, water affected by the magnetic field can be obtained. By the way, when lettuce leaves were put in tap water treated as described above and allowed to stand at room temperature, the water did not decompose at all, and on the contrary, shoots appeared on the lettuce leaves in about 4 weeks. That is, the reproduction of microorganisms was suppressed, while the reproduction of higher plants was vigorous. When lettuce leaves were put in untreated water, putrefaction began in about 4 days. The water activated as described above can be widely applied to keeping the freshness of agricultural products and other fields such as agriculture. By the way, as shown in FIG. 4, when the permanent magnet 34 was processed by applying a demagnetizing field with the same magnetic poles facing each other, an interesting phenomenon opposite to the above was observed. In other words, the growth of microorganisms became active. This treated water can be effectively used in the fermentation industry and the like.

[0012]

Industrial Applicability According to the present invention, it is possible to provide water which can be activated in water and can be used in a wide variety of applications such as fermentation industry, keeping freshness of agricultural products, and agricultural fields. In addition, it is possible to create a flow of water by pumping up the lake water and returning it, and in the middle of that, we made it possible to mix the external air and to let the water mixed with the external air pass through the magnetic field. , The amount of dissolved oxygen can be increased, the decomposition of organic matter, denitrification, and dephosphorization work by the growth of microorganisms, and the electrostatic breakdown of colloidal particles causes clay, iron, manganese, silicic acid, hedoro, etc. The pollutant source can be decomposed and settled, so that the lake water can be led to the purification cycle.
