Since industrialization, treatment methods such as sewage sewage organic wastewater and rainwater wastewater (all of which are referred to as `` sewage '') have been studied and commercialized mainly for a long time, and only recently have added plant ecology methods or plant ecology. It is attempted only by scientific method.

The present invention is the patent application No. 223514 and 232361 and No. 466330 and 490490 and the patent No. 6190553 B1 and Australian Patent No. 743448, which is registered as a domestic patent since 1998 by the same applicant And a method for improving natural wastewater purification using aquatic plants of Turkey Patent TR200101526B and Chinese Patent No. 166397, followed by further refinement and improvement of the purification technology in this field filed by other applicants. It greatly improved the physiological and biological processes, identified the principles and problems of botanical ecological purification, improved the methods for the compositional batch operation of the process, and improved the application to non-point source wastewater such as rainwater wastewater.

In the present invention, in order to purify sewage to a high quality of water in a relatively small area quickly pre-treatment of pollutants by a method such as physical and biological, and then to clean the high water quality as an ecological natural purification by plants, and used plants re-contaminate water It is designed to continue the cleansing function without causing it. Photosynthetic plants inhabit and maintain aerobic conditions around the roots by releasing oxygen, a byproduct of photosynthesis, into their roots first. An example of a reaction scheme in which algae photosynthesize is as follows.

Algae in the above reaction absorb hydrogen ions (⑤) and all other components (①, ②, ③, ④) in a fully combined form with oxygen, and the new biological tissue of ⑥ has no oxygen and the amount of oxygen (⑦) 4,800kg, algae growth is 1,708kg, oxygen production is 2.81 times more than algae growth. Normally, plants with roots send oxygen from the stomach, which is a by-product of photosynthesis, to their roots first, so that aerobic microorganisms always live around the roots, decomposing organic substances from plants using oxygen from plants, Obtaining bioenergy, nitrogen and phosphorus are absorbed into the body to make proliferating cells and the remaining nitrogen and phosphorus are left. At this time, the plant that supplied oxygen absorbs the nitrogen and phosphorus components left by the aerobic microorganisms and combines them with oxygen, absorbs water and carbon dioxide, and synthesizes light as a catalyst to grow the biological tissue of the plant. will be. In other words, the plants grow by sending oxygen around the roots for their own growth and living together with aerobic microorganisms. The symbiosis between plants and microorganisms is a common means of survival for both aquatic plants such as land plants and plants, and aquatic plants such as willows. Such means of survival of plants are shown to people in the animal world that nature purifies its environment.

As described above, the filtration layer of the present invention is a symbiotic phenomena between plants and aerobic microorganisms, so the aerobic state in which aerobic microorganisms inhabit always persists, and thus, the filtration layer of the present invention is composed of fine sand. There is a characteristic that can be done. Therefore, in the filter layer in which the aerobic state of the present invention persists, aerobic microorganisms adhere to the surface of each particle in the fine sand, and can effectively adsorb the organic matter flowing in the low-speed upstream of the entire filter layer and decompose the adsorbed organic matter. It oxidizes it into a form that can be absorbed by the plant, and the plant absorbs and reconstitutes these components as living bodies, so that BOD, COD, SS, hydrogen ions (H ⁺ ) and nitrogen phosphorus in water are lowered together. In addition, bacteria E. coli and general bacteria are higher microorganisms than their own, and are mostly eaten by aerobic microorganisms living in the filtration layer, and most of them are reduced. It will be supplied by the tank so that it will continue to grow faster than on the open ground.

However, the prior art in this field is a treatment water in the application of the principle of midnight, which can absorb nitrogen phosphorus more effectively, when the ecological mutual symbiosis conditions for plants to exchange materials with aerobic microorganisms are properly formed. It is understood that the absorption of nitrogen and phosphorus is improved when the roots of the plants and the plants are repeatedly contacted. However, the streams of the plants are zigzag-style in the left-right direction or zigzag-up in the vertical direction. The compartments are divided into compartments, but the same area is divided into several compartments, and the zigzag structure makes the cross-sectional flow velocity of the water flow relatively fast, so that plants and aerobic microorganisms exchange oxygen and nutrients with each other according to the principles of the present invention. In addition to relatively low mass exchange reactions, The passage resistance becomes large, thereby the flow direction of the water flow is up-flow, or flow port of discharge or even sidewise current sinking in the water plant parts dead water gun 1 to 2 years gradually increasing the passage resistance of hameuroseo residual water flow filtration layer. In addition, the prior art in this field is the type of plants used in the reeds of the reeds that are aquatic plants that are submerged in the whole or a part of the water, yellow irises irises sedge sedges irises irises irises babies It is mainly used for 1 year or perennial submerged plants such as perennial water plants, or immersion plants such as malm screw, crucian carp, black horse, or 1 year to perennial side plants such as water hyacinth water lettuce frog rice dry yellow aryyeon.

As above, aquatic plants, which have been used in the past, are killed for 1 year in the case of 1-year-olds, so it becomes a source of recontamination of water to be treated for several months from the start of death until completely re-decomposed. Treatment performance is greatly reduced. Even perennial leaves die more than 1 year every year, and bulbs and roots die more than 2 years in the habitat. This phenomenon is a common habitat characteristic of the above perennial herbaceous plants. Therefore, from the third year, some purification plants planted perennial plants became another organic pollutant of water to be purified. Therefore, it is possible to remove these dead parts artificially in a timely manner, but the purification performance by dead plants may not be deteriorated, but the removal of these dead parts by hand is very difficult and inconvenient, and furthermore, old bulbs of perennial plants that die in the planting base. The timely removal of roots and roots is not possible due to the nature of the treatment facility such as sewage, which requires operation sustainability, and it takes a lot of cost, manpower, and time to replant after removal. Only passive care is given once a year to cut only the leaves and stems that have been raised above the planting base, which is part of the dead or dead part.

The natural high-purification system of the present invention solves the problem of water recontamination occurring in the above plants by planting the water-variable trees instead of plants that cannot solve the problem of fundamental recontamination due to the dead parts. That is, the willow trees such as the willow trees, the weeping willows, the weeping willows, the willow trees, and the aspen trees, the Italian poplar trees, and the willow trees, if the planting environment where the roots and stems are exposed on the water is exposed to the soil, It is a perennial plant-based plant that grows and grows in a single life cycle. There are many growth points, and they give out new stems immediately, and the wood is softer than other trees in the season, but the growth rate is faster. Twill trees maintain green leaves even in early winter, and most willows start growing in early spring. It also has features of low temperature resistance and long growing season. Therefore, if you create a planting base that does not directly touch the leaves only fall every 1 year, there will be no re-contamination of water in the present invention, so in the present invention, planting these trees in the planting base layer and crushed stone to a position higher than the water layer on the layer. By creating a gravel layer, the leaves that fall every year will not be a source of recontamination even if they are left for several years, thereby solving the problem of water recontamination and difficult management factors that could not be solved in the conventional methods of using aquatic plants. In addition, the above-mentioned trees grow because they continue to increase the volume of trees, and you do not have to cut them every year. The planting tree of the present invention absorbs carbon dioxide gas emitted by the aerobic microorganisms in the process as a result of metabolism in the greenhouse and re-determinates it, so that when the grown shrub is used as a wood material, the greenhouse gas for a long time until the final re-decomposition The reduction function is also accompanied by more characteristics. In addition, these parasitic trees have a much deeper root depth than those of the myriads, and willows form numerous hair roots in the roots of branches. Since it is more excellent, the organic matter is decomposed into aerobic and converted to nitrogen phosphorus to improve the functionality of water purification performance and the growth rate of aquatic trees is also faster. Using this principle, crushed stone in hydroponic medium formed on the aquatic tank of the present invention or near the treatment plant using the treated water of the present invention in order to utilize nitrogen phosphorus in the treated water at the village-level sewage treatment or urban treatment plant as an economic material. It is possible to obtain both water purification function and economic effect by filling the back litter only up to the level of the water layer, laying hydroponic cultivation on it, and planting economical medicinal to edible plant types, flower tree types, and flower herbaceous plants. In other words, instead of planting aquatic plants on the planting base created for the purpose of simple water purification, they fill the gravel only to the water surface and lay a hydroponic cultivation board on it, and medicinal edible trees such as cedar, oak tree, mulberry tree, arbor, and rosewood on it. When planting flowering landscape trees such as camellia, Benjamin, Rose of Sharon, Jaguar, and rooted plants, roots can be laid down to the bottom layer as in the willows to obtain water purification effect and economical materials available. Lily Tulip Hyacinth Narcissus When planting bulbous herbaceous plants such as Amaryllis, most of these herbaceous bulbs are divided into several parts like garlic side to make breeding seeds. Therefore, after harvesting flowers, it is possible to remove old leaves and roots by harvesting seeds every year. It can solve the problem of re-contamination and It is possible to get hweseong gyeongjejae together.

On the other hand, the physical and biological basic treatment process of the prior art in this field is simply abandoned or intermittent aeration in a single reaction tank or the flow control facility was configured separately, and the final sedimentation tank was formed in the conventional top type, but the homogeneous facilities of the present invention Is improved and advanced as follows. In other words, to improve the functionality of physical solid-liquid separation at the first inflow of sewage and to facilitate management, Joe's model has a circular inside, a bottom at the top, and multiple screens are installed horizontally on the set water surface. The intermittent aeration in the reactor was placed after the first intermittent aeration, followed by an anoxic reaction tank, followed by a second intermittent aeration to improve the nitrification and denitrification reactions. The production of sludge is minimized, and the lower end from the bioreactor to the settling tank is opened so that water flows through, so that the decanter can function as much as the water head difference with the aquatic tank. Aquatic tank is placed only on the upper part of basic process. The aquatic tank planting the aquatic vegetation of the name was arranged next to or near the basic process or in the upper part as in the case where the site is narrow. The conventional homogeneous technology is mainly limited to only sewage organic wastewater, but the present invention is rainwater. The application to waste water is an improvement over the conventional method. Rainwater wastewater has low concentration load, large fluctuation load, and very small inflow in winter. The characteristics required for the natural purification facilities of rainwater wastewater should be almost constant management factors, the flow rate can be stored and can be adjusted automatically, and after the rain, the purification facilities should be able to operate automatically by a certain amount for a long time. The way in which it can be operated is suitable, and it is more appropriate that there are no exposed structures such as greenhouses.

The natural high purification system of the present invention can satisfy the purification characteristics required in the rainwater wastewater as described above. That is, in the case of rainwater wastewater, the concentration of organic matter is low and the concentration of SS, such as earth and sand, can be omitted in the purification system of the present invention. Since it functions as a flow control function by the physical sedimentation function and decanter at a certain amount, it is automatically adjusted to be introduced into the aquatic tank 200 by a certain amount, and the crushed stone layer 210 is planted and the crushed stone layer 230 is formed to be exposed on the water layer. Even if it is left alone, there are no management factors such as re-contamination of water, machine operation, operation, and dredging every few years only when a large amount of soil is deposited in the basic process (100). It is manufactured and constructed, and the medium capacity is improved to be constructed by mixing concrete and various kinds of material for the curtain and all of them.

As described above, in the prior art of the present invention, only the aquatic vegetation was used, but the method and technology of utilizing the hydrovariate and hydroponic vegetation (hereinafter referred to as 'aquatic vegetation') of the present invention for sewage, sewage, wastewater, rainwater wastewater, etc. Although there is no example disclosed, the present invention has been provided to provide a novel design to solve the problem of re-contamination and management of water is difficult and the contents of the prior art basic process technology is greatly improved and advanced. In addition, the prior art in this field is the planting base of the present invention composed of a fine sand layer by forming a planting base of the myelin sheath composed of relatively large grains and gravel layer of 2 to 20mm or using porous granular cultured soil and artificial calcined soil As the body surface area is smaller, the absolute amount of aerobic microorganisms attached to the planting base is relatively small, and as the pores are large, the amount of water flowing between the pores is large, so that the flowing organic matter flows away from the adherent microorganisms, thereby degrading the adsorptive decomposition power of the organic matter. do. In addition, the porous granular soil constituting the water layer has many micropores, but if the microorganism enters the micropores, water flow is blocked and oxygen supply is not anaerobic, which is not suitable for forming a habitat for aerobic microorganisms. Since the pores are obstructed soon after the purification by physical adsorption phenomenon until the blockage, the plant and aerobic microorganisms inhabit together and the ecological purification mechanism by material exchange cannot be maintained as stably as the microsand filter layer. In addition, porous granular soil is rare and artificial clay is a material that requires artificial processing to bake soil formed in a high-temperature firing furnace.

As described above, the technique of the present invention solves the problem of recontamination of water by using only water plants in the conventional method of the art and solves the problem of water recontamination by using the method of using hydroponic trees and hydroponics. The aquatic tank of the present invention has been improved to be applied to the purification of rainwater, which is a non-point source of non-point pollution, and the basic physical and biological processes have been improved in efficiency and functionality for each process. In addition to the simple plants that purify the water, it is possible to improve the layout, and instead of using the hydroponic trees or hydroponic cultivation system, the water purification function and economical plants can be produced together. In addition, the construction cost is also improved to be cheaper than the artificial material by allowing all of the aquatic tank 200 to be formed of a natural material.

The present invention provides a vegetation purification method in which water is not recontaminated by using hydroponic trees and hydroponic plants instead of plants in the conventional water purification method for purifying sewage and wastewater patented by the same and other applicants. It is to provide.

In another aspect, the present invention is to provide a purification method for purifying the wastewater of non-point source such as malignant wastewater due to the initial rainfall in a fixed amount in the aquatic tank 200 planted with perennial hydrologic tree without power and greenhouse, and the purification function is continuously maintained. .

In the present invention, crops grown hydroponicly from nutrients of plants remaining as contaminants in the treated sewage were crops such as vegetables and rice, such as lettuce buttercups, which are disgusted for human consumption. It is to provide a way to make the water clearer while hydroponic cultivation of more suitable plants and medicinal plants, such as tree plants, to make the treated sewage available as an economic material.

The present invention is further configured as a rear end facility together with the aquatic tank 200, hydroponic cultivation 245 or aquatic tank and hydroponic cultivation medium according to the present invention in an existing facility or a new facility of another treatment method in which waste heat energy is generated in the basic process. It is to provide a method that can be purified by nature.

In another aspect, the present invention is because the material filling the interior of the aquatic tank 200 is made of a natural material rather than an artificial material, so that the purification purpose can be more effectively achieved, so that the economic cost of construction or replacement is higher than that of the artificial material. To provide an inexpensive natural high purification method.

The present invention further improves and improves the conventional physiological and biological processes to provide a natural high-purification method in which the efficiency of basic processes such as separability and management of solid materials, nitrification and denitrification flow rate automatic control and surplus sludge reduction are all improved. It is to.

The present invention also allows the construction material to be manufactured in a package type as a light material when the capacity to be purified is small, such as sewage, and the medium and large capacity may be constructed with reinforced concrete or water curtain or waterproof mud material or mixed with them regardless of capacity. It is possible to provide various application methods such as the method of constructing the aquatic tank process next to, near, or on top of the basic process depending on the conditions of the target facility.

The above objects can be achieved by the configuration and detailed description of the present invention below.

Sewage sewage organic wastewater using the aquatic vegetation of the present invention natural wastewater purification system (hereinafter referred to as 'sewage') is a basic process and filtration layer 205 consisting of physical and biological treatment as shown in Figures 1 to 4 It consists of aquatic tanks (200) where hydroponic vegetation (220, 221) is planted and ecological self-cleaning phenomena are planted above, and the above process is required when waste heat and natural heat are required, such as sewage production facilities such as sewage, or for the purpose of producing vegetation. The greenhouse 300 is further configured to cover the outside of the. The basic process 100 is a process for rapidly treating water having a high degree of pollution in a narrow space and includes a physical solid-liquid separation tank 110, biological reaction tanks 120, 130, and 140, and a physical precipitation tank 150. The solid-liquid separation tank 110 is one or more screens 111 for separating and filtering the solid material of the influent sewage is configured horizontally in a position where the water does not touch the water layer in parallel and the sewage is introduced into the screen water Pass through the screen and fall down, foreign matter remains on the screen and separated from the sewage, foreign matter on the screen can be easily removed at this time because the water is drained and dried at the time when the inflow of sewage is stopped. The sewage passing through the screen is discharged toward the wall of the solid-liquid separation paper which passes through the L-shaped transfer pipe at the bottom of the screen and forms a circular shape, so that the water of the solid-liquid separation paper is rotated. At this time, the sediment is shorter than the outside of the rotational flow, so the flow rate is collected at the center of the slower flow rate, so the sediment is separated and settled relatively faster than the rectangular sediment flowing into the horizontal flow of the same flow rate. In addition, the fine suspended solids passing through the screen is left to float on the water surface of the solid-liquid separation tank because the structure only flows water to the lower portion of the letter transport pipe 112 is connected to the next place. Since the bottom part of the solid-liquid separation tank is a top model, sediment is collected at the bottom and the suction pipe of the pump is connected to the bottom, and the settling material can be easily taken out to the outside by a timer set to operate at a regular cycle.

The sewage that is separated from the solid-liquid separation paper 110 and transferred to the first intermittent aeration tank is desorbed by the aerobic microorganisms and ammonia nitrogen when abandoned by the intermittent operation of the built-in underwater aeration device 121. Is nitrified and the nitrified nitrogen is denitrified by nitrogen gas (N ₂ ) by the denitrification microorganisms during the aerobic period. At this time, a part of the residual organic matter including the sludge is consumed as a denitrification reaction nutrient source of the denitrification microorganisms and is reduced together. The aeration time and the aeration time are the underwater aeration device 121 which repeats the operation and stop automatically by a timer that is set to an appropriate time zone during the commissioning process in consideration of the concentration of the influent sewage and the residence time. Decomposition, denitrification, and denitrification of organic matter at the stationary are both efficient, so adjust according to the inflow load based on this time.

On the other hand, the lower part of the wall partitioning the first intermittent aeration tank and the anoxic tank, which is the next process, is opened to a height of 15 to 25 cm from the bottom, and the sewage and sludge is transferred to the next tank through the gap. In order to prevent the injection bubble into the anaerobic tank, a double pool wall 160 having a height slightly higher than or equal to the open height of the wall is configured toward the anaerobic tank 130. The sewage flowing into the lower portion of the anoxic tank 130 is stirred by the water agitator 131 to improve the contact between denitrification microorganisms and nitrate nitrogen and the residual organic matter. As contact with and is blocked, re-dissolution of oxygen is suppressed, so that the residual dissolved oxygen of the influent sewage is immediately converted into an anoxic state so that effective secondary denitrification can proceed. Underwater stirrer is running. The rotating water flow continues even after stopping for a while, so the stirrer is operated by the minimum operating time unit such as 5 minutes running or 5 minutes running or 10 minutes stopping without denitrification. It can be set to a timer if possible. The wall between the anaerobic tank 130 and the second intermittent aeration tank 140 is also formed so that the lower end of the wall is opened to a height of 15 to 25 cm, and the sewage and sludge are transferred to this gap and introduced into the second intermittent aeration tank 140. . The second intermittent aeration tank 140 is decomposed, nitrified, denitrified and denitrified nutrient sources of residual organic matter by intermittent operation of the underwater aeration device 141 that operates in the same principle and function as the first intermittent aeration tank 120. It is made repeatedly and the double wall (161, 162) is formed on the inlet and outlet side of the tank 140, respectively, so that the direct water flow and the spray bubble of the underwater bubbler 141 does not affect the left and right sides of the tank. The partition wall between the second intermittent aeration tank 140 and the settling tank 150 is inclined about 30 degrees toward the settling tank so that the sludge slides down, and the lower end portion is also configured to have a height of 15 to 25 cm. The sewage flowed into the lower part of the sedimentation tank 150 is moved up and down, and the sludge is sedimented and accumulated above the height of the fold pool wall 162, and reaches a certain height when the underwater interceptor 141 is stopped. The conveyance is automatically made by conveying to the) and if the amount is large, even the first aeration tank 120 is automatically conveyed, so the sedimentation basin 150 of the present invention does not require a separate conveying device or a conveying operation management. As such, the sludge that has reached the end of the age among the sludges that have been repeatedly transported and returned is self-decomposed into nutrient sources of newborn sludge and denitrifying microorganisms, and thus, in the precipitation and conveying system of the present invention, the amount of sludge is almost eliminated or reduced to a very small amount. It works.

Meanwhile, the symbol water transported to the upper portion of the settling tank 150 is immersed in water only to the wear portion, which is an outflow facility, and is collected in the waterway by the decanter 151 which is automatically moved up and down according to the level of the settling basin. The decanter 151, which consists of buoyant body, waterway wear, and flexible tube, automatically discharges the water adjusted by opening the outlet valves 270 and 271 to the next process at the surface of the sedimentation basin 150, thereby changing the inflow and outflow amount. When the width is small, it operates while operating only slightly up and down to the water level slightly above the set water of the aquatic tank 200, but when the amount of sewage suddenly increases during the event of rainwater inflow or holiday Aekyung slope, the water level rises gradually to the maximum set water level. This leads to the continuous flow of a certain amount of treated water in Shanghai East, so the water flow of the basic process 100 is operated in a continuous flow unlike a batch type. At this time, the process from the first intermittent aeration tank 120 to the settling tank 150 is configured so that the lower wall is all open, the water level of each tank (120, 130, 140, 150) are all fluctuated up and down to the same level. Therefore, it is possible to automatically adjust the flow rate corresponding to the volume of the maximum water level and the minimum water level difference of the decanter 151 according to this characteristic, even if the system of the present invention does not constitute a separate flow control paper and the transfer pump, etc. It will also function as a flow adjustment function. This decanter 151 having a constant buoyancy is made to have buoyancy by blocking both ends of the hollow pipe or to mount the waterway wear on a stirrer foam plate of considerable thickness, fix it to a horizontal position, and transport the water outflow pipe. It can be easily manufactured by connecting with a flexible tube as long as the length. The end of the flexible tube outflowing the water from the decanter 151 is connected to the steel pipe and the steel pipe branches to the T-shaped branch pipes are configured to enter the aquatic tank valves (270, 271) to the direction of the filtered water flow of the aquatic tank 200 Upstream or downstream flow can be switched and the inflow can be controlled. That is, when the inlet valve 270 is closed and the valve 271 is opened, the sewage flows into the distribution tank 260 of the aquatic tank and is distributed through the limestone 204 shellfish shell 203 which is a lime component material administered to the distribution tank. Flows into layer 207. In the sewage treated up to the previous precipitation process, the calcium ions of natural lime components (203, 204) are present because carbon ions from carbon dioxide dissolved in water exist due to the discharge of hydrogen ions and aerobic microorganisms produced by nitrification of nitrification microorganisms. It reacts with to form calcium hydrogen carbonate, dissolves and decomposes in organic material and finally combines with dissolved phosphorus (P) to precipitate calcium phosphate. The approximate total phosphorus (TP) concentration of village sewage is about 3 to 8 mg / L, so about 4 to 5 tons of limestone and shellfish shells with about 90% of natural calcium content is 100 m ³ of sewage per day. It can be used for about 10 years to treat the phosphorus component below the discharge water quality standard, and in the aquatic tank of the present invention, the limestone 204 or shellfish shell 203 is put together in the large gravel layer that is the lowest part of the filtration layer. In addition, the above dispensing tank is open to the top, so that the structure can be administered at all times, after 10 years of exhausting all of the calcium components administered to the filtrate, it is a way to easily supplement the deficiency by additionally administering to the dispensing tank.

As described above, the sewage in which phosphorus is precipitated and reduced is slowly passed through the filtration layer 205 to the top, and organic matter remaining by the aerobic microorganisms adhering to the surface of the gravel and the fine sand of the filtration layer is adsorbed and decomposed and separated from the organic material. The nitrogen component is nitrified by nitrifying microorganisms that inhabit the filter layer. At this time, oxygen required for the decomposition process of organic matter, nitrification of nitrogen component and phosphorylation of phosphorus component is continuously supplied through the roots of aquatic vegetation down to the filter layer, and the plant is finally oxidized with nitrogen As it absorbs water, hydrogen ions and calcium ions, the water is cleared as a result of the ecological material exchange between plants and microorganisms, and the air quality is also purified and repurified by biological plants as carbon dioxide gas is absorbed by plants. Since the growth is continued in the open field or other methods and supplies a lot of oxygen back to the filter layer, the conditions for the rapid reaction of microorganisms inhabiting the filter layer can be continued. As described above, the aerobic filtration layer does not decay as the soil of a plant inhabited forest or pollen soil does not rot, and thus, even if the filtration layer is made of fine sand, it does not rot or close. The sand layer 201 at the top of the filtration layer is composed of a waterwayware 250 having a plurality of V-shaped grooves for forming a relatively shallow water layer 208 and is about 6-12 cm higher than the water surface of the water layer. The layer is further configured, and the waterway cover 250 is covered with a waterway cover 251 made by cutting half a section of the pipe. In the crushed stone layer 230, a plurality of trees 210 are planted at regular intervals or fill the remaining gravel 231 only up to the height of the water layer instead of the crushed stone, and the hydroponic cultivation plate 240 is placed thereon, and the hydroponic tree 230 or hydroponic is possible. The super flowers 221 can be planted. Water slowly passing through the filtration layer from the bottom to the top of the crushed stone layer flows into the close V-shaped groove of the waterway wear 250 flows out to the treatment tank (280). The crushed stone does not fall into the waterway wear 250 by the waterway lid 251, and the fallen leaves falling from the variegated tree 210 are stacked on the crushed stone layer 230, so the water and 6 cm or more are separated by about 12 cm so that they do not rot and are dried naturally. It will not be a source of pollution. The crushed stone layer 230 has a planting environment where the root and stem portions are separated in the water layer, where the roots are well extended to the water layer or the soil sand layer with water. It will be planted willow, poplar tree, aspen, etc.). These trees have roots that extend straight to the roots and branch roots to make a number of roots in the branch roots, so in the present invention, the important function of evenly supplying photosynthetic oxygen to the bottom of the filtration layer of the aquatic tank to shallow roots It is an excellent feature compared to. Water purification plants, which are herbaceous plants that have less need for deep roots to withstand strong winds compared to woody ones, have a common rooting effect on plants with shallow roots and deep roots on the surface of water purification facilities, which are rich in nutrients. This is because it is represented by the format characteristic of phosphorus.

Although the functionality of supplying oxygen to the filtration layer than the above-mentioned water tree 210 is somewhat inadequate, it is a tree having many advantages over the herbaceous plants, in order to purify water while obtaining economic material from pollutants of water. Instead of forming a small residue (231) to the top of the water layer (208) and laying a hydroponic cultivation board (240) on it, which is economical as a tree (220) that can be hydroponic at regular intervals. It is possible to plant medicinal and edible types of trees such as trees, to plant flowering trees such as rosewood, camellia, Benjamin, rose of sharon, and evergreen, or to plant plants such as lilies, Tulip hyacinth, Narcissus, Amaryllis, etc. In this case, the hydroponic cultivation medium 245 can be largely formed, and even in this case, the treated water and residual nutrients according to the present invention and waste heat energy generated in the basic process can be utilized as a greenhouse, so that the production cost is higher than that of the artificial hydroponic medium. As it is lowered, hydroponic cultivation with price competitiveness can be combined with water purification. These trees (210) and hydroponics (220) are grown to a certain size and then cut off the bottom or top of the stems, and soon they grow out of new growth points of the stems and continue to grow. There is no risk of dead water in the foundation, so there is no risk of water recontamination. In addition, hydroponic cultivated plants are bulbous herbaceous plants, and after harvesting flowers, new seeds are made from bulbs like garlic. Therefore, management work to remove old leaves and roots during the seeding process may be performed every year. Therefore, the problem of recontamination of water by the dead part of the plants can be solved, so that it can be a method of plant purification and economic production according to the present invention. Therefore, the aquatic plant purification method of the present invention solves the problem of recontamination of water that could not be solved by using only a few kinds of plants in the past, and it is easier to manage, and the carbon dioxide gas can be re-established for a long time in proportion to the stock volume. It is to provide a technique for producing economical medicinal flower plants together.

Naturally purified water from the aquatic tank 200 is collected in the waterway bank 250 and exits to the outlet valve 281 connected to the flexible tube to the treatment tank 280 to perform a disinfection weighing process, which is the next step (not shown). Through the water. At this time, the water in the treatment tank 280 is cleared to the second-class water quality of the domestic law river water, so that fish and shellfish can be inhabited, such as the koi carp fish, and soybeans. And video equipment to monitor the inflow load and treated water quality from time to time to remotely control the operation stop time of the moving equipment, and to check and remotely manage the vegetation status of the aquatic tank and the habitat status of the fish and shellfish of the treated water tank 280 in the central control room. A system that can be configured is further included in the natural high purification system of the present invention. Therefore, in the case of a village-level treatment plant, it is possible to immediately check the control room for inflow of poisonous substances such as pesticides from farms to the site and to deal with them immediately.In case of large fluctuations in inflow and concentration such as holiday events, etc. It is a natural high-level purification system that can operate the operation remotely from the central control room.

However, in the site conditions where it is difficult to receive electric power, non-point source wastewater such as rainwater wastewater can be purified by the natural high-purification system of the present invention. Compared with the natural high purification system of the present invention, which is not configured as a power device, since the pollutant concentration of most organic substances is very low and nutrients such as floating substances and nitrogen phosphorus are problematic, the purification facilities of FIG. 1 or 8 or FIG. 10 and 10-1, it is possible to automatically adjust the flow rate and plant trees, not plants, because there is no management factor of aquatic tanks and there is little rainfall in winter so there is no need for greenhouse and waste heat energy. Automatic control of the flow rate of the components Filtration and sedimentation of foreign substances Aerobic decomposition and nitrogen intake It can be purified to a satisfactory level by water, and the construction materials can be manufactured in a package type by using plastics or iron materials at a small capacity. The medium and large capacity can be constructed with reinforced concrete and water curtain, and the bottom of the reservoir can also be used as a waterproof mud. Can be installed. If the bottom of the reservoir is constructed of waterproof mud or laid a water curtain and the soil is mixed with a gravel sand layer thereon, the reservoir can be planted in the water purification plant 210 for the reservoir.

On the other hand, the lower portion 207 of the aquatic tank 200 accumulates a small amount of non-volatile matter (FS) that does not decompose during the long-term operation of the facility, so check the amount of deposition every five years to clear the treatment tank 280 Water is pressurized and transferred to the pressure pump 291, and the high-pressure injection is carried out by the injection pipe 290, and the washed deposit material is transferred to the suction pump or dredging vehicle or the concentrated place (not shown) in the facility by the transfer pump 292. It was designed to maintain the performance even if the facility is operated for a long time. In addition, even in the case of rainwater wastewater purification facilities without power equipment as described above, it is possible to construct injection pipes and connect portable engine pumps if necessary, or clean and take out the deposits as above by dredging vehicles. It's a long-term operation that's durable.

In addition, the system of the present invention, as described above, the operating method of the aquatic tank 200 is normally operated as an upflow, but if necessary, the downflow can also switch the operation. When the rivers flood, such as during the rainy season, most of the sewage treatment plant flows with the soil. Especially, the village unit treatment plant washes soil-produced agricultural products, farm equipment, shoes and work tools, and the soil water flows into them. It is not so good that it enters the lower distribution layer 207 of the aquatic tank 200 and moves upwards. When it sticks to the interface between the gravel layer 202 and the sand layer 201 for a long time and sticks for a long time, it forms an ocher film and forms an upward flow of the water stream. There is a problem that gives a great resistance. In the conventional various water purification method using various water plants, the yellow soil membrane has not been devised so that the treatment plant of the same type in which soil water has been introduced for more than 3 to 4 years is gradually decreasing its original treatment volume. The viscous ocher membrane is not removed even when the water is removed from the lower portion in the present invention by switching the inlet valve (270, 271) and the outlet valve (281, 282) in the operation method of the aquatic tank 200 in the downflow for a long time The operation made it possible to remove the yellow soil. That is, the water of the aquatic tank to be backwashed by the transfer pump 291 from one treatment tank 280 of the aquatic tank 200 configured in parallel is emptied by transferring to the other distribution tank, and then the inlet valve 270 is opened and the inlet valve 271 is opened. When closing and closing the outlet valve 281 and open the valve 282, the symbol water of the sedimentation basin flows into the waterway 250 of the aquatic tank and passes through the filtration layer 205 in a downward flow. At this time, when the suction pump 292 is operated, the lower end portions 202, 203, 204, 205, 206, and 207 of the aquatic tank 200 are all empty, so that a water layer is formed on the yellow soil layer under the sand layer 201, and the yellow soil is filled. The membrane bursts and flows down. After the ocher film is sufficiently removed, the cleaning water is sprayed into the injection pipe 290 to wash the floor, and the soil water is carried out by the sludge treatment process to the transfer pump 292. When the backwashing operation by the downflow is completed, the inlet valve 271 is opened again, the valve 270 is closed, the outlet valve 281 is opened, and the valve 282 is closed. The other aquatic tank next to it is operated in the downflow as above, and the backwash is cleaned and operated normally in the upflow. In addition, the blockage of the vegetation base based on the inflow of ocher soil as described above, in the conventional method using only the myelin, since the root of the myelin does not extend deeply to the gravel layer under the filtration sand layer, the ocher membrane layer is formed and at the same time the water flow path obstacle is severe. However, in the aquatic tree main use method of the present invention, the roots of the tree mains extend far deeper than the plants, and the straight roots and many branch roots extend deeply under the gravel layer, and these roots continue to make new roots and grow in length and thickness. As a small gap is formed between the yellow soil and the roots through the membrane, the resistance to pass through is much less than that of the use of aquatic plants in the same conditions. To act.

In addition, under the sand layer 201 of the upstream filter paper, various microorganisms discharge metabolism and gas dissolved in the influent is eluted to form an air layer, which gives another resistance to the water flow passage, thereby gradually decreasing the amount of passage. There is a present invention solves this problem by configuring a plurality of air discharge pipe 252 at regular intervals. The purification method according to the present invention uses the treated water and waste heat and uses the hydroponic cultivation method of the present method more actively for the purpose of economic income, as shown in FIGS. 9 and 9-1. ) A separate hydroponic medium (245) is formed with a shallow depth of gravel or water layer and expanded to a single greenhouse so that the waste heat of this facility can be used directly, or covered separately by two or more greenhouses, and a waste heat transfer pipe is installed. As a consolidation method, fertilizers and other nutrient solutions can be used to produce economic goods at a lower production cost than artificial hydroponic cultivation methods, which require additional heating costs.In this way, contaminants such as sewage can be removed and converted into usable economic goods. This purification method is located at or near the top of the facility, even in most other treatment facilities where waste heat energy is generated. When the aquatic tank 200 or a separate hydroponic medium 245 of the present invention is formed as shown in Figs. 5 to 7, the residual nutrients in the waste heat and the treated water are recycled into available resources in the same manner as in the present invention. An economic crop can be harvested continuously and water is clearer. That is, the application range of the aquatic tank 200 and the hydroponic medium 245 of the present invention can be seen from all new facilities and existing existing facilities that use the basic process 100 in a different manner as shown in FIGS. It is possible to apply the natural high purification process by the aquatic vegetation of the invention.

On the other hand, if the capacity of the sewage to be purified, such as the technology of the present invention has a very small capacity and a large number of places to be installed, the construction material of the structure 170 is relatively light and easy to transport construction plastic type or stainless steel plate, etc. to facilitate the construction of the site As a steel material of the package (Package) can also be manufactured in one-piece or assembly type, as shown in Figure 10 and Figure 10-1 package facility also consists of a structure that can perform all the main functions of the present invention, the production model is a cylindrical oval It can be manufactured in various ways such as square. In the case of medium to large capacity, as shown in FIG. 1 or FIG. 8, the structure 170 can be applied regardless of the capacity by constructing a mixture of reinforced concrete or reinforced concrete and a water repellent or waterproof mud material. As shown in the above example, the basic process 100 and the aquatic tank 200, the method of manufacturing and constructing the hydroponic cultivation 245 is to be easily adjusted by those skilled in the art in various ways not shown in the present invention. In addition, in the case of rainwater wastewater, the amount of wastewater is small in winter, and the amount of wastewater is low and the concentration of organic matter is low. Therefore, the remaining process may be performed as shown in FIG. 1, FIG. 8, or FIG. 10 and FIG. In the absence of a greenhouse, planting trees can be left to grow for decades, thus minimizing management factors as a natural high-purification facility in the open field. As described above, it is easy for a person skilled in the art to add or subtract a part of the purifying system according to the place, the use, the capacity, and the object to be treated, all of which belong to the scope of the present invention.
