The present invention relates to a method for purifying contaminated river water, and more particularly, to form an upper outlet and a lower outlet in a support structure, and each having an opening and closing door to block these outlets, while selectively lifting and lowering each opening and closing door. By selectively opening the lower and lower outlets to alternately discharge the upper and lower streams of the stream to effectively purify the contaminated river water.

As is well known, it is obvious that large amounts of contaminants are included in the incoming water since water is introduced through various paths into reservoirs such as rivers or reservoirs. Therefore, various methods have been proposed to purify the stored water, and conventional water purification methods include gravel contact oxidation method, reverse contact oxidation method, sewage treatment plant water purification method, chlorine input purification method, etc. Compared to the effect was insignificant.

In order to improve this, a device has been introduced to implement water purification by forming a vortex in water through a separate device to float contaminants and removing it, but this has the disadvantage of having a separate device to improve the water quality. Of course, the water purification area is very limited, so it was vulnerable to water quality improvement in a wider range.

In addition, the "natural water quality improvement method using a multi-stage water storage device" of the Patent Publication No. 2001-0000343, which was created by the present applicant, has a natural self-cleaning effect due to aeration because it is composed of a single gate. There was a very low flaw, which caused the green algae, which was caused by the aggregation of substances and contaminants generated by the confinement of water and contaminants trapped inside the water gate, which caused the algae to be stored more and more. There was a serious defect that worsened.

Here, the term applied to this invention is demonstrated in order to raise the technical value of this invention.

"Material Acceleration" and "Material Scavenging" and "Law of Material Preservation Instinct" and "Material Aggregation" and "Material Coupling" and "Material Rejection" in which contaminated water quality contained in river water is naturally purified or deteriorated. Effect ”and“ material release ”.

Due to the difference in the mass and specific gravity of the substance, all the substances flow in the different places of the material, ie in different states, depending on the specific gravity of the substance.

By this action, clean water with heavy gravity flows in the lower layer of river water, and polluted water with light gravity flows in the upper layer of river water. The reality is that it flows faster than the lower seawater. This action occurs because the amount of pollutants contained in the water, ie the pollutant load, is high. This principle is defined as the "material acceleration phenomenon".

The reason why the water flowing in the stream is more polluted is because of the "acceleration of substance" and "agglomeration". Lightweight polluted water flows into the lower part of the river while lightly polluted water flows to the lower part of the stream by the action of gravity caused by the rotation of the Earth and the solar system. Pollution in river waters is further aggravated by the deterioration of contamination by "agglomeration", which combines with other pollutants that have been introduced.

The following describes the process of the "material indentation" that occurs when the material acceleration phenomenon is reversed. There is a close relationship between mass cutting action and material acceleration. The process of material ingestion is performed when contaminated river waters try to pass through the lower part of the hydrology, and the waters forming the river water are pushed to the upper part of the clean water with heavy gravity and then to the upper layer. Through the lower part, it tries to escape first. This principle is called "material cutting action". It is defined as. All materials on earth are different in volume or specific gravity, even if they are the same size, depending on the atomic weight and molecular weight of the materials that make up the material.

Next, all substances are "laws of substance preservation instinct," which seeks to instinctively preserve the essential components of the substance, "mass aggregation" exerted by these actions, and "substance release" caused by material thrust. The operation will be described. Water has the characteristic of inducing another substance by instinctively accepting the penetrating substance and integrating the substance when water other than water penetrates into the structure of the water by the structural characteristic of water. In the present invention, such an action is defined as a "mass aggregation action".

In addition, when a certain impact is applied to water to shake off the contaminants that penetrate into the pure water molecular structure forming water crystals, the contaminants contained in the pure molecular structure of the water are immediately released from the water molecule. The action that comes out is "material release". It is defined as. In other words, the action of cleaning the polluted water by the force of impact from the outside is the "material release action". It is defined as. As described above, the mass-aggregation action is generated when the water storage system is constructed in such a way that the water storage system for confining the river water is discharged to the upper end of the inflowing river water such as concrete beams, conductive water gates, or rubber dams. Pollution is aggravated by, but if you install a hydrologic system that discharges the river water to the lower end, the contaminated river water will be naturally purified as the natural material grabbing action, material jungle action and material release action. Large dams can also be constructed in this way so that they do not add pollution. In addition, the installation of a hydrologic system configured to discharge only a portion of the stream water in the lower part of the water storage system increases the pollution. As the material is pushed by these heavy clean waters, it is pushed out of the outlet, and the pollution is further aggravated by the agglomeration of substances that combine with other pollutants. Due to material jungle action and mass aggregation, contaminated river water with a light weight other than the hydrosphere's outlet is absolutely impossible to move downstream of the stream itself, and combines with other substances. Contamination of contaminated materials becomes more and more contaminated by condensation. More specifically, the installation of a siphon-type water gate configured to selectively discharge only a portion of the outlet water formed at the lower end of the rubber dam or a portion of the bottom water trapped in the lower portion of the conductive water gate will result in a heavy gravity of clean water. Polluted waters that have a high specific gravity by pushing out these light waters and exiting the material first are pushed by clean waters that are heavy, and remain stagnant inside the water gate. In the state of absolutely failing to escape to the downstream part, the contaminated materials are bundled together and the contamination is further aggravated by the condensation of materials and the conjugation of materials that combine to create another material. When the water is confined using a submerged beam that discharges the influent to the upper part by these actions, the material condensation action and the substance generated by condensing the contaminants and water molecules together while confining the water inside the reservoir system There is a significant problem that contamination is rather weighted by the binding action.

The following describes the "law of substance conservation instinct," which is one of the findings of this study.

All matters are rejected and pushed away if other foreign matter penetrates into the material structure of the material by the natural property of the material by the structural property of the material. Or the action of trying to escape from the substance or contaminants to permanently preserve the pure structure of the substance is defined as "law of the substance conservation instinct" in the present invention.

The following describes the "substance rejection action" caused by the "law of substance conservation instinct".

When all substances enter the water, they are diluted with the substances mixed in the water, and the aggregation of substances that add water pollution is not exerted from the beginning, but the structures of pure water molecules are bound directly by the substance rejection action that rejects the pollutants. In other words, it rejects the agglomeration effect of substances and substances, and after a certain period of time, pollutants are released by natural reactions such as dissolved oxygen, solar heat, microorganisms and osmotic pressure. It gradually combines with water molecules and transforms into contaminants. As these substances are naturally decomposed again, the particles generated by natural decomposition are combined with other substances, which increases the pollution of the water. This is caused by the active green algae and the red tide occurring in the sea. A substance called a terrestrial animal is a by-product of the aggregation of organic and inorganic substances.

The following describes mass decomposition, mass binding and mass flotation. The pure molecules of water react to try not to combine with other substances due to substance rejection caused by the "law of substance preservation instinct" to maintain pure water molecules. They are bound by mass-binding action that binds to molecules and at the same time become heavy, and decompose by the natural decomposition that occurs naturally while sitting on the bottom layer of the river. A repetitive action occurs in which the material binds to the water molecules and some of the pollutants coming from the upstream.

Contaminants contained in water molecules change into microparticles by self-decomposing self-decomposition, and then repeatedly bind to other contaminants while exerting repetitive flotation, which moves to the upper layer of the reservoir. The water molecules bound by are repeatedly bonded to become heavy at the same time as they are bound and sink to the bottom of the reservoir, increasing the pollution of the river water. They are called "mass decomposition", "material binding" and " Material injury action ".

The following is the definition of "material decomposition" and "material binding" found in this study.

Even though all materials are lighter or heavier than water, they are gradually worn out as the sharp parts of water molecules come into contact with the materials by the pressure generated by the water pressure when they enter the water. The substances begin to decompose spontaneously, at which point the particles of the decomposed substances are separated between the substances and the substances by the viscous force contained in the particulates, that is, the viscous and magnetic forces contained in the decomposed microparticles from another substance. Bonding takes place and this is the material binding action. Particles generated by decomposition of materials naturally have viscous and magnetic forces because water tension naturally occurs due to surface tension as they move and wear over hundreds of millions of times. .

The new materials produced by the material binding action generated through this process are heavier than the specific gravity of water, so that the material bonds and settles down to the reservoir where it is stored.

At this time, a large amount of material binding action is generated by a continuous action in which material decomposition takes place again through a continuous process in which materials contained in the sedimentation sludge are decomposed again. Phenomenon and red tide occur. The cold rust produced by iron rust is the fine particles of the material decomposed by water molecules, and these particles combine with other particles to produce other materials.

Organic matters, inorganic matters, phosphorus and nitrogen contained in water are transformed into fine particles through the action of oxygen, microorganisms, solar heat and the natural decomposition of water molecules. As the material binds, it turns into heavier particles than water.

However, when the water flowing down from the upstream to the reservoir where water is stored is discharged according to the inherent mass of the material due to the laminar flow acting according to the law of material grabbing and specific gravity, Because the binding action is not made because the pollution is not aggravated, rather the contaminated water quality is to be purified to naturally purify.

Therefore, if the water is confined to a certain place for a long time, the contamination is further increased by the material decomposition and material binding action, so that the water stored in the reservoir space is discharged through the sluice and refilled with new water. It is the best way to prevent water, and also to discharge the water in the reservoir, discharge it to the lower part of the gate and discharge the pollutants such as sedimentation sludge which are aggregated by the material binding action, In addition to the method of purifying water by the principle of action, material flotation action, etc., it is most desirable to discharge the water to the upper part of the sluice to remove and remove polluted substances having a light weight on the upper part of the water.

However, in the case of general hydrological gates, the supporting shaft of the hydrological gate is located at the lower side of the supporting structure, and the conductive hydrological gate discharges the stored water to the upper portion of the hydrologic gate while conducting according to the water level. It is limited in purifying river water because its supporting shaft is fixed like a floating gate that discharges the stored water to the lower part of the gate, so that the water stored in the reservoir can be discharged only to the upper or lower part of the gate. In addition, in the case of the conducting sluice, there is a problem that the regressive water can destroy the ecosystem because it cannot form a passage of fish when going back to the river to find the place where it was first born. In the case of floating floodgates, there is a sudden increase in water, such as flooding, which causes large foreign objects such as tree branches to float out. When that was also concerned by these hydrological damage the larger debris.

The present invention has been proposed in view of the above points, and the upper and lower discharge ports are formed on the supporting structure installed in the transverse direction in the entire cross section of the river, and each of the opening and closing doors is provided with the opening and closing doors to block these discharge ports. While descending, both the upper and lower outlets are opened or closed, or the upper and lower outlets are selectively opened one by one to alternately discharge the upper and lower streams of the stream to effectively clean the contaminated river water. It is to provide a method for purification.

Hereinafter, the present invention will be described in detail with reference to the disclosed embodiments and accompanying drawings.

Figure 1 is an exploded perspective view of the river water purification hydrograph according to the present invention, Figure 2 is a cross-sectional view when the entire closure of the river water purification hydrology according to the present invention, Figure 3 is a cross-sectional view when opening the lower outlet of the river water purification hydrology according to the present invention, Figure 4 is a cross-sectional view when opening the upper outlet of the river water purification gate according to the present invention, Figure 5 is a cross-sectional view when the entire opening of the river water purification gate according to the present invention, Figure 6 is a detail of the opening and closing door connection portion of the water purification water stream according to the present invention 7 is a cross-sectional view of each outlet portion of the stream for purification of river water according to the present invention.

As shown, the water purification gate for the river according to the present invention, while the support structure 10 in the horizontal direction in the river is configured to store water in the storage space formed through it, the upper one side of the support structure 10 and On the lower one side, the upper discharge port 11 and the lower discharge port 12 having a shape having a length in the transverse direction longer than the length in the front direction are formed to pass through the front and rear of the support structure 10, respectively, of the support structure 10 The storage space side is provided with opening and closing doors 30 for opening and closing the upper discharge port 11 and the lower discharge port 12, respectively, and withdrawal of the operating rods 31 in the outward direction on each side of each opening and closing door 30, respectively, The rod 31 is connected to the piston rod 41 of the lifting cylinder 40, respectively, the lifting cylinder 41 is fixed to the support structure 10, respectively, the opening and closing door 30 according to the expansion and contraction of the lifting cylinder 40 While raising and lowering the upper outlet 11 and the lower outlet 12 together Open or closed, or the top outlet 11 and bottom outlet 12 and is constructed to open one year.

In addition, each opening and closing door 30 is configured by connecting a plurality of panels 32, between each panel 32, the tightening bolt (in the state in which the packing member 33 is extended to the inside of each panel 32 ( 34, the extension part of the panel 32 and the packing member 33 are tightened together, and the guide groove 35 is provided on the opposite side of the support structure of the packing member 33 located at the connection part of each opening and closing door 30. It is formed in the vertical direction, the guide groove 13 is formed in the guide groove corresponding position of the support structure 10 to guide the lifting and lowering of the opening and closing door (30) while the connection portion of the opening and closing door (30) is floating by the water flow To prevent it.

In addition, a plurality of pillars 20 are formed on the inner side of the upper outlet 11 and the lower outlet 12, and the pillars are formed to gradually decrease in width toward the tip portion toward the water flow direction, and The tip is rounded to prevent foreign matter from getting caught in the column.

At this time, the storage space side surface of the support structure 10 in contact with each opening and closing door 30 is formed to be inclined obliquely downward, so that each opening and closing door 30 is in close contact with the supporting structure 10 by the hydraulic pressure and gravity.

If the flow rate is not large in this configuration, as shown in Figure 2 by extending the lifting cylinder 40 as much as possible by pushing the operating rod 31 of each opening and closing doors 30 downward through each opening and closing door 30 The outlets 11 and 12 are closed, and in this state, water is continuously filled in the reservoir.

At this time, if the water stays in the reservoir for a long time, the contaminants are increased by condensation and contaminate the river water rather than being decomposed naturally. Therefore, when the water is filled to the reservoir, the water is frequently filled. Should be discharged.

To this end, as shown in FIG. 3, when the lifting cylinder 40 connected to the lower opening / closing door 30 is contracted to raise the lower opening / closing door 30, the lower discharge port 12 is opened so that the water of the storage space falls out. In this process, foreign matters such as sewage sludge deposited on the bottom of the river are released like the stream water by mass aggregation, which causes material acceleration, material cutting, material desorption and material injury. This can be purified.

In addition, the water level of the reservoir can be kept constant in this process, as well as the lower discharge port 12 can form the movement passage of the fish when the fish moves upstream, there is also an advantage to preserve or maintain the ecosystem.

As described above, even when the water is discharged to the lower outlet 12, the polluted material having a lighter gravity is shrouded in the upper portion of the stored water, and the condensed material is aggregated with the newly introduced contaminant over time. As mentioned above, it is possible to increase the pollution.

Therefore, with the discharge of the lower portion of the reservoir space through the lower outlet 12, the water of the upper portion of the reservoir space should also be periodically discharged. For this purpose, the lifting cylinder connected to the lower opening / closing door 30 as shown in FIG. When the lower discharge opening 12 is closed to extend 40, the lifting cylinder 40 connected to the upper opening / closing door 30 is contracted to raise the upper opening / closing door 30 so that the upper discharge opening 11 is opened. As a result, the water of the upper portion of the reservoir can be drained and the polluted substances having a light weight in the upper portion of the reservoir can be discharged together to purify the water quality.

Of course, the lifting operation of each of the opening and closing doors 30 is not shown, but by detecting the pollution state of the water through the sensor installed in the reservoir space can be automatically operated by controlling the power unit, and also to the appropriate program By the upper outlet 11 and the lower outlet 12 can be opened and closed periodically, it is obvious that the administrator can directly control manually.

However, when the quantity is very large and the water pressure is very large, such as flooding, huge pressure is applied to the support structure 10 and each of the opening and closing doors 30, as well as water may overflow the support structure 10. As shown in FIG. 5, each lifting cylinder 40 is contracted as much as possible to open both the upper outlet 11 and the lower outlet 12 so that the water escapes rapidly through the upper outlet 11 and the lower outlet 12. The water level can be properly maintained in a short time as well as to protect the support structure 10 and each opening and closing door 30 safely.

On the other hand, each opening and closing door 30 according to the present invention is to open and close each outlet (11, 12) having a long length in the horizontal direction, it is difficult to configure a single long panel, therefore, a plurality of short panels 32 ) Is connected to each other, the panel 32 and the packing member through the tightening bolt 34 in a state in which the packing member 33 extends to the inside of each panel 32 between each panel 32. By tightening the extended portions of (33) at once, it is possible to prevent leakage through the connecting portions of each panel 32, it is possible to maintain the shape of the overall opening and closing door (30).

In addition, since the packing member 33 is made of a flexible material compared to the panel 32, the packing member 33 may be swung by water flow, and thus the lifting direction of each opening and closing door 30 may be shifted. Guide grooves 35 are formed on the opposite side of the support structure of the packing member 33 located at the connecting portion of the 30 in the up and down direction, and the guide protrusions 13 are disposed in the corresponding guide groove positions of the support structure 10 in the up and down direction. Therefore, the guide projections 13 are inserted into the guide grooves 35 of the respective opening and closing doors 30 so that the sliding doors are brought into sliding contact when the lifting and lowering of the opening and closing doors 30 is made. It can be guided, of course, to prevent the phenomenon of the connection portion of the opening and closing doors 30 is caused by the water flow.

In addition, a plurality of pillars 20 are provided on the inner side of the upper outlet 11 and the lower outlet 12 so that the supporting structure 10 may be loaded even if the weight of the supporting structure 10 itself or any weight is applied above the supporting structure 10. 10) can be smoothly maintained, each column 20 is gradually narrower in width toward the tip toward the water flow direction, but the tip is formed rounded, so foreign matter is discharged when the water in the reservoir is discharged Even if it is discharged together, the contact area between the pillar and the 20 is narrow, so that it can be discharged as it is without being caught, it is possible to prevent the foreign substance is caught.

In addition, in the present invention, the lifting cylinder 40 is illustrated as a device for elevating the opening / closing doors 30, but each of the opening and closing doors can also be lifted by a screw, a rack-pinion, a crank, a cable traction device, etc. in addition to the cylinder. It is obvious that the embodiments also belong to the scope of the present invention.

In addition, the panel 32 constituting the opening and closing door 30 may be made of any material such as metal, synthetic resin, wood, etc., depending on the shape of the river, such as adding a heavy material or made in a hollow state inside the opening and closing door 30 It is natural that such modified embodiments also belong to the scope of the present invention can be configured in a variety of shapes.

In addition, although not shown, it may be configured to cover or attach a packing member around each of the outlets 11 and 12 to prevent leakage between the opening and closing doors 30, and each of the outlets 11 and 12. It is apparent that the foreign matter may be collected by installing a foreign matter filtering net at the middle or one end portion of the support structure, and also a separate fish may be formed on both sides of the support structure 10. It belongs to the scope of rights.

In addition, the method of purifying the contaminated water quality using the method of installing the configuration of the present invention in the river in multiple stages is also within the scope of the present invention.

Since the present invention is a method for purifying contaminated water quality using a structure configured to store water over the entire cross-section of a river, a design change that is different from the configuration of the present invention may be variously modified. It is natural that the method of purifying contaminated water quality using a method of storing water over the entire cross-section of a river by different means belongs to the scope of the present invention.

The position of the hydrology applied to the present invention can be used to cut and insert the middle of the structure, and by installing a hydrology on the rear of the structure can be configured to purify the contaminated water quality, such design changes are all seen Naturally, it belongs to the scope of the invention.

8 is a cross-sectional view of a water purification gate for purifying water according to another embodiment of the present invention, in which the rubber dam 50 is fixed to the entire upper portion of the support structure 10 in the horizontal direction, and when the rubber dam 50 is installed, Since the volume is small because air is not injected into the inside, the installation and handling are convenient. When the air is injected into the rubber dam 50 while the rubber dam 50 is installed, the rubber dam 50 expands. Water can be stored up to the upper end of the rubber dam 50 has the advantage of increasing the amount of storage.

At this time, the rubber dam 50 is basically composed of a material such as flexible natural rubber, artificial rubber, flexible synthetic resin, in addition to any material can be applied as long as it is flexible and can withstand water pressure, accordingly rubber dam (50) Even if it is configured by changing the material of these modified embodiments are naturally belong to the scope of the present invention.

As described above, the present invention can open or close each outlet, or selectively open and close only the upper outlet and the lower outlet one by one to confine the water in the reservoir, or to discharge the water in a short time to stabilize the water level It is possible to discharge the pollutants of the lower reservoir water with water or to discharge the suspended matter from the upper reservoir water with water, so that the polluted substances contained in the river water are naturally purified. “And“ Material Scavenging ”,“ Law of Material Preservation Instinct ”and“ Agglomeration of Material ”,“ Material Coupling ”and“ Material Rejection ”and“ Material Release ”and“ Material Decomposition ” It cleanses purified river water and cleans contaminated river water. For that would have effects.

In other words, the polluted water is not only purified naturally while staying in the reservoir, but also prevents secondary pollutants that create new pollutants by blocking the mass aggregation caused by the condensation of contaminants and pollutants. As the water is discharged, the aeration is caused by a drop, which makes it possible to realize more active water purification through the natural purification of the water itself and the floating of foreign substances by the aeration. If installed, the water can be purified more naturally through each step.

Therefore, this system can be used to purify polluted river water easily at low cost even in the case of large rivers, and can create completely clean river water because it uses the natural purification system naturally generated by nature. It is effective in producing clean water without using chemicals such as chlorine and fluorine. When applied to a large dam it is possible to reduce the occurrence of sedimentation sludge in the dam, there is a significant action effect that can prevent the green algae caused by the above actions at the source.

In addition, there is a significant effect that blocks the source of the red tide caused by the flow of polluted river water from the land of the land flow into the sea.

Also, no matter how much water is trapped, the stored water does not decay, so you can not only trap a large amount of water, but also because of the capillary phenomenon caused by the trapping of the water, Due to its status, there is a significant action that promotes the growth of trees growing in the mountains, and this action prevents the desertification of the land caused by drought, and has a significant action effect that transforms the desert into clay. .
